A friend of mine is almost done with his 302 build which includes 30 over 302 with pop-ups (unknown comp ratio), comp cams magnum solid cam advertised duration 306\306, lift .592\592, lobe sep 110, victor jr intake & holley 750 double pumper on extensively ported 302b iron heads unknown valve sizes but I know they are oversized, c4 with 3500 stall and 4.10 rear gears on m.t et slcks 26x10.5 His car (strip only) is slightly heavier than my capri so I reckon about 2950lbs. My set-up is similar just a milder cam, 40 over with pop-ups, worked iron heads, vic jr & 750 holley, all msd, c4 & rear end & tyres are the same, my capri (strip only) weighs in at 2600lbs.....It,s no biggy to me if he,s set-up is faster (ha!ha!) but I just wanna be prepped coz I know he's also good at the lights.....Cheerz Rob.

300lbs is a big difference... given all else equal, he'd have to be making 30-40hp more than you to make up for the weight difference. It'll be close, will probably be down to who launches harder.

Sounds comforting Tony....I was just thinking that he might have an edge on me with his wilder cam, I thought his cam profile would be too heavy for the 1/4mile but nobody seems to be commenting on that so I guess it will work for him......can't wait to up-grade to 408ci.

The cam is a little on the too-big size for a 302 unless he plans to rev that thing to 7500+rpm. What are the "302b" heads?

He'll be a slug out of the hole, but it'll come on strong once he gets past 4,000. Problem is, the heads will probably run out of steam at 6,000-6500, no matter how big the valves.

Burn him in the first 330' and you'll have him.

No guarantees though.

I just checked the rpm range for that cam and its 3000-7000 rpms.Since its a solid cam and he's using a victor intake I don't think its gonna run out of steam at 6000 rpms.He could probably use a little more convertor and gear but the thing might come on like gangbusters once he gets it wound up.I have never heard of those heads though so that could make or break the combo...
