I am rebuilding a basically stock 302 for my 1990 F150. I want a little more torque from the motor than stock, but it doesn't have to be a monstrous increase. Can anybody help me out here?

302
EFI
AOD tranny
3.55 gears (changed to 4.10's at a later date)
31" tires.

When I redid my '73 302, my builder I wanted more torque. My builder recommended a Schneider cam. It may be the same one that K bar S (Bronco specialty house) sells. The motor seems to run very strong.

Here is a Desktop Dyno simulation of the engine that I had built for my Mustang way back in the summer of 1992. It's basically bored 0.030, a little bit of exhaust port work, planed heads, 600cfm vac sec Holley, shorty headers and a Comp Cams 270 Magnum (224 @ .050 with .500 lift) and approx 10.5:1 compression. It has a pretty nice flat torque curve but I really don't know, this combo might be a little too much for off road use but then again it might be perfect.

When I freshened up my 351w, I put an RV cam in. I am not sure of the specs. It was from PAW mail order, their house brand. I works very well. I am happy with it.

Split pattern cam - more lift on exaust side - SB Fords need help on the exaust side.
Stay away from lots of duration - Headers will help A Bunch.

I have had good luck with the Comp cams Extreme 4X4 series cams in my 4X4's. There are 3 or 4 different grinds.

What you need to do is just weld on the top of the lobes a little. That will make your little rocker thingies move up and down a little faster. I did it to mine and I gained at least 200 more HP. <IMG SRC="smilies/rasta.gif" border="0"> <IMG SRC="smilies/innocent.gif" border="0">

Hey Rob, how's the D60R swap going?
Sorry to butt in. Just couln't help myself.
