On my street notch, I'm makin over 300 to the rear wheels on a mustang dynometer, carbed, with outta the box protopline heads (which aren't the worst but they're not that great). It's not hard at all to reach 400 to the wheels with a decent setup.

I dont know of any 5.0 302s making 400 at the tire, not without a stoker.
All the peeps saying its easy I would love to see it. Dyno sheet ect...

If we are talking crank Hp that is just a well thought out 302 combo and its been done many times over.

A 64cc chamber would bring the compression down to about 8.65:1. Not ideal but not bad enough to make a big difference from the factory 9:1. The stock intake is going to restrict your combination a bit. I see you said there were new rings installed on the factory pistons. Was the block honed at the time this was done? Were the rings installed properly? I'd do a leak down test and see where every cylinder is at. Even a compression test would give you some info. I wouldn't be worrying about any chips or tunes until you get the car to run right. I've run many combinations with factory speed density and never had a chip or tune. If it is running sluggish and feels down on power there is a problem somewhere. Or maybe its not down on power at all and you just don't notice much of a difference??? Have you run the car at the track yet? A timeslip will tell a story.

400 FWHP from a 301.5936 aka 302 c.i.d. is just a combination of well chosen parts. Roughly 330-340 RWHP equates to 400 at the flywheel. A pump gas friendly compression ratio 9:1, off-the-shelf hydraulic roller cam, long runner intake manifold, EFI, and peak power checking in at less than 6,000 rpm, will get the ball rolling.

hey darrell thanks for the replys bro, I'm actualy going to the track tomorrow, sat night. I will post up my time slips but my question is that my local track is at like 5900 feet above sea level, so obiviously everthing is slow as shit up here. Will you still be able to get a decent idea from that? The block was honed, the rings were installed correct, the car doesnt burn any oil or anything. I'm gunna run it and if you think it's way off I'm gunna do comp and leak down test. Thanks bro

Hey Darrell, I never ended up making it down to Cecil this past spring. I'm making another stab at it this fall. I have a couple tweaks to add to it this year in hopes of a loss in e.t. Plans after that include a flycut stock short block and more duration. Something with a shift point @ 7,000 -7,200 or until it let's go.

When the secret comes out, you need to sell me that cam......or at least tell me what one you are running I could make alot of money around here with a combination like yours. People would look at it and say "that car runs low 12s/high 11s". Good luck with the et reduction. Truely an impressive combination the way it is. Any faster is an added bonus.
