You guessed right. I recommend the Edelbrock Performer RPM.
Ok, with approx. 10:1 compression, Keith Craft Stage 2 Edelbrock heads, Crane 349521 cam, long tube headers and mufflers, Performer RPM, on a .030" overbore 390, you'd be making 513hp @ 6500rpm, and 487ft-lbs @ 4500rpm. The torque at 2000rpm is 398 ft-lbs, so you really wouldn't be lacking down low either. The Performer RPM is rated up to 6500rpm, so I think it'd be fine on this engine.

Are the KC Stg 2 heads the ones priced @ 2295.00??? also, are they the same heads( less the modifacations) that I mentioned above?? I've a hunch they are but want to make sure.
IF they are, damn thats a lot of work done to a a pair of heads. makes me weak at the knees thinkin' about it. a lot of $$$ too!!!!!!

WOW!!!! 3k for a set of heads!!!! holy bajesus!!! I'll stick w/ the stock Edelbrocks I saw in summit for the time being cause I'm not that diehard.....yet....does that mean that the heads cost the $2995 and to ad the porting is an additional $2300??? That's worth more than my 93' I'm currently driving.
Anyway, basicly if I were to stay away from the real expensive parts for now I'd be well under 500 lb. ft. of torque....and that'd translate into either the TKO500 or TKO600 and if either is chosen there's no problems of underrated trannys and failing parts???? If that all makes sents.

If your thinking about heads look into the Shelby aluminum heads. Around $2100. The stage 2 heads from KC are kickin though. Still the beast buy are the Edelbrocks at $1200 for stock heads with 2 size combustion chambers to choose from. The Blue thunder heads are out and priced between the Edel's and the Shelby's. $1800 seems to be the average price. Ask KC about them.

Yes they did. The standard 1.680" compression height piston was used to lower compression on truck 390's. This was also the standard 410 piston, and works well in them. That's why it is easy to build a 410, since the only thing you need is a 360 / 390 block, a 428 crank and the 390 truck pistons. I'm surprised more people arent building 410's.
