I've heard and seen from a lot of peoples power numbers that the dual pattern makes more power, and like he said its more to make up for a weak exhaust port. Due to the engine bay and design of almost all Ford heads, the exhaust port is a little weak, though I must admit that the Victor Jr. heads sport a good size exhaust port. For price though, you cant beat the TrickFlow TrackHeat cams. The stage 3 would be my vote, Summit PN TFS-51402002. Its a dual pattern roller with a 3500-7000 rpm power range, .574/.595 lift, 236/248 duration, and its only $160! Thats a mean momma cam for a good price and probably will run great with those heads since its for the same power band and the lift is safely under what the Vic Jr springs are rated for, .650. This cam with the Vic Jr intake and heads and long tubes would put you exactly where you need to be and for roughly $2300-2500 for the HCI parts. That isnt including your headers, and fuel stuff.

All of this is useless unless you have the car with the right drivetrain to work. Better be ready with some 4.56 gears, a high flow 3 inch exhaust and full length 1 3/4 headers.

Not to mention that this thing will be a lopey beast to drive on the street. You will soon be tired of it.

Scrap trying to show off to your friends and point that money in the direction of a power adder or a stroker.

That is what I figured about the motor, HCI for about 2300 + fuel stuff is not too shabby. I think it would be wise to put some light weight slugs in there too but I think that a stock block all cleaned up would be strong enough for that kind of power. I just don't want to have to dump a whole lot of cash into a Sportsman or something if it isn't necessary.

I know that it would not be a great street car but that is not the point either. It would be a toy and something to show off to my friends. Besides, a high RPM 302 is not exactly the most common motor around and blowers are common place. And if you think about it, all told it will run you just about the same for a sweet paxton set up anyway.

I see your point hllon4whls, but again, this would be a dual purpose car: Track mostly and street just to show all my Honda buddies that a 302 can wind out too. If the only thing that I have in common is high RPM, then that is fine with me. I have to relate to them some how.

Well, sort of....kind of hard to compete with those cammed and chipped S2000's at 8800 rpm...

LOL. Yeah well, none of them have an S2000. And they are fast and all but nothing that hey have comes close. One of my buddies has a Civic that will do high 8s in the 1/8th. VTEC and all that crap. I respect him totally and it is a sick car as it handles great. The other has a 2001 Integra Type R that is pretty sweet. It pulls hard in 3rd. He is running 9.6 1/8ths bone stock. So I know that those Hondas wind up real good but man, you know where I am comming from. I have always loved the sound of a 302 turning 7500. And that is a hell of a lot more moving parts too. Twice as many as I can figure it out. And they still get pissed when I tell them that a set of Aluminum heads run about $1400 and they have to spend $2200 for one non-ported VTEC job.

How about that their header costs twice as much as my headerS. In any case, yes Hallon we all know that but that wants a high winder and thats the info Im going to give him. Imports are gay. My first combo cost me like $2000 and ran 8.8 in the 8th and that was with only a cam, headers and intake and carbed.

Wasn't referring to the track competition Paul - was referring to the "wind out" competition... Yup, lots more rods, pistons - but I think the same number of valves, springs -- gotta love those 4 valve heads!

Roger that Mike. Forgot about that 4V thing.

Thanks Smock for delivering me the goods even with peer pressure.

I don't think you are goign to get a very broad powerband with a 302 that turns 7500 rpm. Without some kind of VVT, you will have to give up on the bottom to gain on the top or vice versa.

Seems to me that if you are going to go autocrossing you will want to build for torque so you can power out of turns and from low rpms when you have to slow down. I'd do a 331 or 347 and cam it for 2000 - maybe 6500 powerband, gear it accordingly and go with it.

Keep us posted on how your build goes. Should prove interesting.

Whatever makes you happy. I just know that with a big hydraulic cam in my race car, I dont know how I would drive this thing on the street. I originally wanted to, but I never did. The cam is in its power band to 6500. It idles at 1500 and drives like a dog below 2700 when at the track.

Good luck though.

Thanks for the advice guys. I still think it would be a great idea to build a high revving 302 but now that Smock has done some posting about that 392, that has got me thinking...How much effort would it take to keep that an EFI and how much heavier would it be?
