my mission: to consistently see 11's or low 12's on my 350! buut i need your guys' help, im running 8.8's in the eighth with good consistency but am looking for a combo that will definentely put me in the 11's.

ive been reading a lot about solid cams and am considering going with maybe something like the isky z-25,(ive got a 3500stall now) also, im thinking of maybe trick flow 23* becasue i have a source for new assembled ones that are 750 or 800 bucks, considerably cheaper than the 940 bucks they want in summit! my other consideration on heads would be the Pro Topline 64cc but havent heard to much about them. my 70 has 4.56's out back now that came on the car and a th350. so how about some suggestions? intake? carb? any other cam recommendations? id like to go with AFR's but i dont have the money to spend on those as of now thats why i like the price of the trick flows. id also like to keep it somewhat streetable, beacuse i enjoy driving my 70 to the track, about 30min from my house. soo lets the comments roll! thansk alot for the replies guys,

Connor

Get the Trickflow, and spend the money to have them ported.
You'll have a 300+cfm head for a little over a grand, so dollar per
dollar its the way to go! If you get the over rated AFR, you'll have
a 280cfm head for the same money - why bother.
Check out my "383 dynoed" post, it made 490hp with an almost
smooth Idle cam. If you do the same thing with a 350 it should
make close to the same power, runs some high 11s and be real
streetable too.

Are you keeping the 4.56's?

Rod

hey again,

yes i will be keeping the 4.56's i understand they might be a little much, but they came with the car and arent to bad, ive been driving it to the track nearly every other weekend and havent had any problems yet.

Ok, just wanted to establish that. http://www.camaros.net/forum/smile.gif It will have an effect on the rest of your parts choices of course.

I can't argue with what was said above about heads so I'll leave that alone.

-You'll want a fully prepped block
-balanced lower assembly (pistons, rods, crank)
-considering your gears and stall the cam could be on the more aggressive side, the Isky you mentioned should work well. At a minimum 235 @ .050 duration, the Isky has 240 I believe. You could go even a little bigger than that.

Here is a combo very similar to what you are looking to do: http://www.chevelles.com/forum/Forum4/HTML/010530.html

There should be some useful info for you in that thread.

Rod

Also, with your gears, I would definitely look into a single plane intake manifold especially after reading some of the recent discussions on this board.

EDIT: Can you share your source on the heads?

hey guys, thanks a lot for the replies so far, the source for the heads is strokermotor.com they have AFR's too but at regular price. shipping is like 40 or 50 bucks, but fortunately for me they are in my city, and i can get them free of shipping!

Connor

With the deep gear, I hope you plan to wrap that baby up!

I'd do somethin like this.

Super Victor intake
950 HP Holley
Trick Flow heads with upgraded springs, pocket ported, bowl blended
Comp 300AR Mechanical Roller
~12:1 compression, should run on 94 octane

Probably rev to just shy of 7k rpm and make 550-575 Hp.

Go over to www.chevelles.com (http://www.chevelles.com) and do a search in the performacne section under the name Pat Kelley. His setup is running 12.0's with 4.56's with a 350.

Travis, I linked to a discussion about Mr. Kelley's combo in my post above.

Here's another alternative.

I don't know the guys compression (11 or 12) or cam type, but since this is the "stock" class, I'd assume he's running a LT1 mechanical cam. Notice the intake. It has a quadrajet 4 bbl. 5.13 gears. 11.4 in the 1/4. Notice the rear suspension.

Take all the decals off and you could fool a bunch of people.

Lose some weight on the car.

Keep unsprung weight to a minimum.

I run a 4.11 gear w/28.5X10.5 slick, 2900#

Hey 67rs502,
Whay do you say that the AFR's are over rated - just curious?

Put a blower on it. You'll run 11s if you can get traction.

There's nothing wrong with AFR.
But there are some cheaper ways to go about it, like Trickflow, and make the same power.
Or get a set of cheaper heads and port them, and for the same money (TFS+porting) you'll make more power.
AFR's have a flat floor, which makes for a tight short turn radius and the chambers shroud the intake valves - it takes alot of grinding to unshroud the valves. They're a good head, but why spend $300-400 more on purchasing AFR heads??? They need porting just like any other heads to make good power.

Why would you want to buy a set of heads then send them off to be ported just so you can make the same power as a set out of the box for the same total money. I think the AFR would still be better becuase they have not yet been ported and have the potential left to upgrade. There was a post a while back where someone dynoed a engine w/ Trickflows and AFR 195's and the AFR's made like 50 more horse.


David

You might want to look into Canfield heads. Chevy high performance posted alot of different flow numbers for heads, and the canfield numbers were pretty good. I am not sure sabout their pricing though.
NO2 is an easy horsepower gain. You should be able spray 125-150 shot on the same combination you have now and should run 11's, although you may have to go to a little bit higher gear, like 4:11's.
Just somthing to think about.

Here's a good example:
My buddy spent around $1400 on a set of 195
CNC 195 AFR heads (flowed 279/194cfm)for his 406 (440hp/500tq)
I spent around $1100 on a set of 215R TFS heads, then ported them and got 301/236cfm, for my 383 (490hp/495tq)

Look at the price difference, flow #s and hp+tq numbers and tell my which is a better deal? (you could pay someone around $300 if you cant clean them up your self and still break even on price, but would still have a better head and make more power!!!)
Cant make it any simpler then that.

Shift, you are incorrect, the base AFR heads are already 70% CNC ported. You can pay an extra $500 to get 100% CNC porting, but IMO, the extra cost isn't justified for the relatively minor increase in flow. If you bought the 100% CNC ported heads, I wouldn't think you would get any more power by porting them more. Otherwise, AFR would hog them out more.
