Re: opinions on cam selection

Thats a health cam for a street driven 302.It will have a pretty good lope to the idle.The short lobe centerline will put so mid range back in it especially with the fairly large heads.Plan on shifting it at about 7000 at the drags.

Re: opinions on cam selection

That is a lot of cam and huge runners on a 302, I bet it would pull to 8k.
The cam already has .555" of lift with 1.5's, by going to 1.6's your going to have more lift, you should def. check your piston to valve clearance.
Don't run that cam unless you have at the very least 11:1 or higher.

The only Mustang I'd ever own is a Fender.

Re: opinions on cam selection

yep, i built it to handle 8k. i ran out of room to post a pic of my valve clearance, ross pistons have deep reliefs cut in them. i plan on running a tko 500. it has 3.08 gear now but that will more than likely change that to a 3.73 or 3.55. if im not mistaken the erson solid roller im running is bigger than the stock dz cam but smaller than the 30-30 cam.

Re: opinions on cam selection

That cam is bigger than the 30/30 and the off road cam (lift wise)
I thought the DZ's got the same cam.
With the tko and over drive, you will be good with a 3.73 or 4.10
It would be a dog on the street with 3.08's
I didn't realize that cam was a roller either, certainly superior to any of the f/t cams of the day.

Re: opinions on cam selection

with the tko low first is the only reason i changed my mind on gearing. i planned on 4.10 with a muncie at first, but im thinking more about 3.73 tko combo. i meant the 140 offroad, but i was talking about duration.

Re: opinions on cam selection

430-450 @ the crank?
What brand are the heads, and what exactly has been done to them, flow #'s, was the motor blue printed?

Re: opinions on cam selection

they are pro-filer, you cant beat them for the price and they are american. there is another thread on here comparing them to comp. CNCed afr's... the afrs flow more but not by a lot. all i did was hit them with the cartridge roll and clean them up since thay are just cast. i didnt put them on a flow bench. i blueprinted and built the engine myself. i was hoping for about 380 - 420 at the ground. this is my first v8 car never thought i would actually own a 69 camaro

Re: opinions on cam selection

it wont let me put a picture of the piston to valve clearance on here, i could email it tho if anyone was interested. i even tried to put it in my photo album and share it with everyone but said that was a invalid file.

Re: opinions on cam selection

Maybe I screwed up, but I get 11.7:1 SCR and 9.1:1 DCR - both seem pretty high for a street driven car.

Re: opinions on cam selection

I have a 302 built before you were born. .030, 5.7 rods 15.4 domes, large crane hydraulic(lost specs)VR JR, 3.73. It does not have good street manners and no low torque at all, but will rev to high heaven. If you are going to the track fine, street you will not like it unless you enjoy contact with the local constabularies. The Vr Jr doesn't come on until 3500 but will handle 8500 rpm. Mine has been estimated at 400 -450 HP by several mechanics and computer programs. I am going to make changes shortly.

i will hopefully take it to the track some, maybe even some vintage road races. the DZs werent known for thier streetability, but high rpm powerhouses meant for racing. Its gonna tickle me to death just being able to drive it, i have never had a nice vehicle so im not used to comfort anyway. i just wanted a 69 camaro with some balls without having the run of the mill setup. i wanted to keep it small block and i fell in love with z28s so why not build a 302, and shut up my buddy and his a 08 Mustang GT. i did my research when i was picking my parts, i know what i got myself into and i appreciate the concern from you guys. im young and i wanna act like it. i might change my setup in 10 to 20 years when i want more street manners but until then i may have to run 93 octane with mixing some 110 in there. thanks to everyone who is posting on here, i appreciate all comments.

Kind of off-topic, but I would expect the 302 with the specs you're listing to be pretty "soft" and unhappy running at lower revs (like below 3k or so?). As such, I would strongly consider the TKO600RR trans over the TKO500. The 500 has a relatively wide 1/2 gear split compared to the 600 and the 600RR. The 600RR has a tighter 4/5 gear split that I think would play well with a high-revving 302. You don't have the same overall ratio spread as the base 500 or 600, so you'll be revving a but higher on the highway, but the tight ratio drops will make it a blast to drive with 3.73's or 4.10's

Re: opinions on cam selection
