I have an extreme energy comp cam I forget most of the specs but it has a 512 lift and the heads are stock with the exception of new springs to go with the cam otherwise engine is stock
The motor I'm building is running: -This cam: Duration 262/272, Lift .448/.472 -No carburetor; A ported '87 Thunderbird HO intake manifold with multiport fuel injection does the same job. -Ported C9TE stock Ford truck heads -Stock 1968 302 cast pistons (I believe) This is an extremely budget-oriented build, and should still provide quite a bit of oomph.

Since you asked about 302s and not 347s I will tell you my old combo... 9.2 to 1 compression with A Ford racing X-303 hyd roller cam. .545/.545 lift 224/224 dur. @ .050. Offenhauser tunnel RAM with 2-450 Holleys drove it anywhere ,anytime I wanted,great street manners And would run 12.45 @ 109 on pep boys radials and 12.20 @112 on slicks Any time you wanted.
Those are some pretty stout setups! Makes mine look wimpy! I thought mine was a bit hard to drive on the streets! Details in my sig below...Custom ground cam, so I don't know all the specs. It was originally ground for a fox-body mustang, running a heavily nitroused 5.0. I got it as a hand-me-down, and made the rest of the valvetrain work with it.
Come on guys! dont let the thread drop that easy.

Idles at 850rpms all day, ran a best of 11.82@113.7mph with a s#!t 2600 stall torque converter that has 24.7% slipage bogging till the tail lights pass the tree! just orderd a new 4000 tci. All the math comes out to a 11.35 @123 if all goes well in my 2700# ride!
There is no such thing as a HO 5.0 SEFI intake in a pre '91 Bird/Coug... The lowers are same but upper has a smaller throttle body opening... The 5.0 in the Comet is bone stock, but I have a Trick Flow headed and cammed 5.0 in a '88 T-Bird... Also has Cobra intake, 65mm throttle body, 1 5/8" shorty headers, full 2.5" exhaust system...
my 302 has stock iron heads with an edelbrock air gap intake my cam is a comp extreme energy with a 512 lift I dont remember the duration but the rest of the engine is stock except the lifters and valve springs to go with the cam and headers Im upgrading my engine to a 347 stroker with all forged internals and aluminum comp heads the 1.7 roller rockers were said to bring my cam lift up to I think the machine shop said a 544 lift.
