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. My 306 Iron gt40s fully ported ss valves, comp 990 outer 975 iner springs, cobra 1.7 rockers vic jr intake, 800 dbl pmper moddifide fox body 1-5/8 bbk equal shortys Old trw 11.3 pistons, pollished chamber and piston top let me run 91 oct. cool clean alaska air helps too. 555 in/549 ex, 236/244 @.050, 108 lobe sep, 104 intake centerline. 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.
