That's right. I'd like to get these numbers or better with stock heads, crank and rods. Have a D4 block that will be cleaned up, lined, bored, honed and decked. From what I've learned reading many threads the crank and truck rods can handle 500 with a good balance and assembly. The only reason I mention them is because I have no desire to go any combination of stroker so PLEASE don't even bring it up. I also don't want to spend money on a RETRO anything or increasing valve sizes. The stock heads will be ported and get a good valve job. Also I have some good roller tip 1.6 rockers I'll be using and a Eddy performer intake. (not an rpm. I know, but it was a freebie) Can someone fill in the blanks for a good flat tappet cam, carb (thinking a holley 600-650?)and piston. Any help is greatly appreciated.

You are going to have a very hard time making this goal with stock heads and stock valve sizes, even with the heads ported some. Airflow is where the power is, GT40 or GT40P heads would really help, as would most aftermarket heads like Dart Windsor and Windsor Jr. About the only stock head that has a chance is the 69-70 4V Windsor heads, and they will need a generous amount of porting and at least 1.94 valves.

Find some heads off of a torino, or something of that nature From 1974-69.
There are no exhaust humps, and you should easily make more power with no porting.

Nice intake/cam/headers and you should be right at 350 no problem. Use craigslist. You should be able to find these relatively cheap.

Anyone else? It seems that the biggest hurdle are the heads. I may be able to pick up a set of bare iron Trick flows for dirt cheap. NIB. 1.94 in. 1.60 ex. 68cc chambers. Under $300. Good deal? Any idea how much HP these could support? How about a cam/piston reccomendation. Not building a race car. Just want a solid reliable engine for a 2500 lb. Kit car.

GOOD DEAL!!!

Smog era heads and cams lie at the heart of the poor performance of those engines regardless of brand. Replacing them with modern well thought out heads alone are worth 40 to 60 HP. Put in a fairly mild cam of about 200 degrees and .45 inch lift and with a decent header exhaust and intake and you're looking at an easy 350 to 400 ponies without braking a sweat.

Yep, that is a smokin' deal. Jump on it.
