my brother got his 010 4 bolt block, we're gonna have it machined if it checks out alright.
Just wanted to ask, whats a good crank for a decent price. crower's are a bit pricey, lunati pro series isnt bad. He wants to make it a 383
and what rods are nice, so far Crower Sportsman Stroker look nice rods look nice, and only cost $450.
We're gonna use SRP pistons, but which rings do you guys like better Childs and Albert dura moly or Speed pro plasma moly?

Have you looked at SCAT? They have some pretty good prices on forged stroker kits. I have heard some good and mixed reviews of their stuff. Be sure to use quality studs like ARP and speed pro file fit rings are the industry standard.

I tend to think if he's gonna be in the power range allowed by a hypereutectic piston, he can also use a good cast crank. The SCAT 9000 cranks are rated to 7k rpm and 550hp. The SRP's will fail before that crank does.

I like the Eagle SIR rods. Pretty light, and again plenty durable with good rod bolts. Can be had for well under $300. The SCAT 9000 crank is around $300. I think SRP's are what $350? There's your rotating assembly for under $1k, and it'll hold up to anything other then huge amounts of n20/boost.

You may consider Weisco pistons. $430 a set, including rings. Much stronger/lighter than the SRP's.

I looked at some aftermarket rods for my DZ 302 and had to send a few sets back as they were not up to my standards. The ones I ended up with were the Eagle SIR's. They are realy nice ignoring the price. I needed bushed rods so factory pieces were out of the question for strength reasons. I only have a 3" stroke but the motor will see 7000 rpm. When I got them back from the balancing shop I had to call just to verify that they had actualy done the job on the rods and he had to tell me where to look to see any metal removed. Really small as they are well matched out of the box. My machinist uses them in his circle track car too. Eagle makes a quality rod for sure. The higher performance pieces are probably even nicer. There are other choices but those Eagle's are the ones I trust my matching number DZ 302 engine with. Good luck!

I'd determine exactly what power level you are looking at. Why waste your money putting pistons that can handle only 400 HP on rods and a crank that can handle 600 HP? Keep all the parts at about the same quality level - the assembly is only as strong as the weakest part. Here is my opinion on the subject.

GM cast crank, resized rods with ARP bolts and cast pistons - good to 400 HP. 2 bolt block is fine.

Aftermarket cast crank, aftermarket I beam rods and hyperutectic pistons - good to 500 HP. I like 4 bolt blocks at this level personally, but I've heard 2 bolt blocks are still fine.

Forged crank, H beam rods, forged pistons good to 600 or so HP. Need a 4 bolt with some block mods like hard block, splayed caps, etc.

Exotic pieces (like expensive forged pistons, 4340 cranks, machined rods, etc) for big power - like 600+ HP. Your pretty much looking at an aftermarket block to do it right at this level anyway IMO

Just my opinion.

ps. I like the Eagle reciprocating assembly - it comes with a new Eagle cast crank, Eagle SIR rods, KB pistons. Mine seems to handle 450 HP just fine. I'm pretty sure you can also get a forged kit with forged crank, H-beam rods and forged pistons.

Camaro, I agree with Joesmith69. You should get the wiseco pistons, thats what I bought and they kick ass. I bought them from www.dirttrckthunder.com (http://www.dirttrckthunder.com) for $430. Shipping is free and you get everything you need, including nice hastings plasma moly rings. Although they have raised the price to $449 its still a good deal. Also check out www.flatlanderracing.com, (http://www.flatlanderracing.com,) check out the pro-line cranks and rods. $399 for a 5140 stroker crank. I shopped around when I bought my 383 bottum end, and I got a bullet proof setup for about a $1100.

I just bought a scat 9000 int.bal crank and scat H beam rods from flatlanderracing.com and was very pleased w/ there service. crank was $289 rods $359. Thats for the 6" stuff.

Shane

were looking at about 420hp, but only too 5500 rpms. i like the suggestions. we decided on an Eagle Cast crank, we think that should be up to the job, and the crower Rods, i'll look into the wiseco pistons, i've seen some awsome wiseco deals on Ebay too.
The lunati one is a bit overkill.
We dont want to go into outspace with this thing, but it doesnt need to be cheap ethier. 4 grand for the block/heads and cam is what we're looking for and he might switch to fuel injection.

Fuel injection would be sweet. Something I wish I had done instead of my carbed 383 is an injected 350. A sweet street combo I thought of would be a 350(all good cast bottum end), Edelbrocks performer rpm pro-flo EFI,and some trick flow heads,and a mild hyd.roller. I almost went EFI but its spendy, maybe next project. Or better yet maybe Ill win the lotto or somthin.

Anyway, the eagle crank would work. Ive seen the cast steel one go for $140 many times on ebay. Scats steel cranks have awesome machine work for the price. I bought one for under $200 once that was dead on, and had a very nice polish to it.

i'll check them out.
My brother wants the EFI and its his money, so i'll edge him to get it, so we can see how it works http://www.camaros.net/forum/biggrin.gif

im a firm believer in cast steel cranks and a good i beam rod. my 406 rotating ass. (eagle) has a cast steel crank, sir i beam rods (floaters), srp pistons,(a damn good piston) je plasma moly rings, and clevite bearings. w/ this exact same bottom end kit, my machinists 406 dynoed 500 hrse, and he used to squeeze 200 hrse in the 1/4, never had a single problem w/ it, and ran 10s in his full size 2wd blazer. that was enough for me. i wouldnt mix & match rings myself, just use the rings your piston manufacturer recommends. also, IMO the scat setup is similar to eagles, probably just as good, and you can get an internally balanced crank if you go 383, which is nice. just my .02

10's in a Blazer http://www.camaros.net/forum/biggrin.gif Now wouldn't that be fun to tow a boat with!

Wiesco pistons do kick ass but i was just informed JE & Wiesco are both owned by SRP.I tried Total Seal rings Iwould never use another ring again
68SSS

thanks guys, i think i've got my brother talked into Crower sportsman "stroker" rods (require no clearancing) and an Eagle cast or forged crank. Probably cast, since its less then half the price.
I'm using eagle SIR's in the 355 i'm building (still!) and so far they just look nice and pretty sitting in the box they came in, but i cant wait to try them.
I figured the SRP's to be a nice piston, i guess we'll just use the rings they like.
I dont want the total seal, heard good and bad, and since we dont get lucky i'll go for the tried and true.

Nobody said anything was wrong with the quality of SRP pistons. But they are still Hyperucraptic, no matter what way you slice it. Go with the forged stuff from Weisco.

i have to respectfully disagree w/ you about srp's being hypereutectic, they may make 'em, i dunno, but the ones i got w/ my rotating assembly are most assuredly forged

The crank is your back bone, yes cast will handle the HP you are looking at. Hyper pistons are quieter then the forged. In my little opinion I would spend the extra for a forged crank and if possible same for the pistons as I'm not concerned about the noisy forged pistons (I kind of like it - sort of the mech cam or gear drive timing set feeling you get just from hearing it) pretty poor and stupid excuse. But the real reason in my opinion is, it's just a matter of time before he decides to spray with NOS and the cast crank and non forged pistons won't handle it. Some guys are getting away with 75 HP to 100 HP with non forged products but it's a time bomb in my opinion. Also I would use the same justification and put in the best bearings (mains and rods) he can afford. Just my opinion.

What's wrong with hyperutectic pistons? I run my KB's hard in my 383 and they are VERY GOOD pistons if used for the right application. I put 70+ 1/4 mile passes and 7000 road miles on mine last summer. When I took the heads off this winter I wiped them with a soft rag and gummout and they shine like new. The cross-hatch pattern on the cylinders from honing looks like it did when I put the engine together.

The only people I've heard talk bad about them either didn't have any first hand experience with them or sprayed too much NOS with too much timing!

turns out we may get a ROSS piston, since they make em lighter, less expensive and in the .040" over and 3.75" stroke.
Pete he isnt going to spray it, i'd put money on that. he doesnt want to drag it ethier, he only wants a nice street car. he also doesnt want to grenade the 700-r4 he just put in.

Eric,

You're right. I came off a bit harsh. I just am one who believes you can't overbuild your shortblock.

CnC,

You guys will be happy with the Ross pistons. Just about as nice a piston as you can buy.

thanks joe, i dont want to let my brother down on this one, so i'm doing my research. i talked him into the comp 280HR roller cam (224 duration, nice sleeper cam) talked him into building a new engine, and now i'm basically telling him what parts to get.

BTW, whats your experience with the SRP's to have such a dislike to them?
Glad to hear wiseco are performers, becuase i can get good deals on them through ebay, or just buying them through a mag they're still inexpensive compared to JE.

CamaroNotCamero, I like your choice of the Crower rods. Can you tell me where you can get a set for $450, I've looked around the net some and most every place I've seen wants full suggested retail of $585. Thanks.

Like I said before, I came off too harsh on the SRP's. I'm not saying they are a bad piston.

That said, whenever I build an engine for myself, or reccomend something to somebody for a performance engine, I will recommend a FORGED piston. I was under the impression the SRP's are hyperuetectic. I like the forged because although today's goal may be say, 400hp, you never know where you'll go from there, and you'd hate to have to tear down your shortblock just because now you wanna make 500hp, or run a 150hp shot of N20...see where I'm commin from?

joe, i understand. i appreciate you looking out for me too.
John, i got that price on crower's website. they look like nice rods, cant wait to give them a try. and they're the sportsman, not the lightweight or billet.

I'm using SRP pistons. All SRP's are forged. And they are very good. They are not machined as much as a JE or Ross piston and typically use an alloy more suitable for street/strip as opposed to all out racing. Nonetheless, they are good to at least 500 horse.

lawrenceville, wow mark we're practically neighbors! keep an eye out for a gold 67' if your cruising around. i'm near trenton.

Anyways. good to hear about the pistons. I'm gonna go for wiseco, less expensive and heard lots fof good about em.

Thanks for the info on the SRP's.
