The combo I'm working on.
71 400 block but not a cold weather block, just a 230 number. I stripped it down bare. Knocked all the freeze plugs out, cleaned up behind them as good as I could, took all the oil galley plugs out, and had it vatted so I could inspect it and pre install the crank to see if there is any interference. I will bottom tap all the holes and wire brush out all the lifter oil galleys along with the complete oil system. I will end up installing all 4 outside pistons at all 4 corners to see the piston to deck height without the rings as to have the block decked to get it close to zero deck or 5 in the hole.
So far my build plans are 499 440 source crank, eagle 6.760 rods, and diamond pistons. I will choose a piston that will get me to around 13 or 13.5-1 comp.
I plan on useing the stealth cnc ported heads they offer for 2k. They claim around 320/238 flow numbers @ around 650 lift. I am useing one of my roller cams I have laying around. Around a .475 lobe lift with 1.5 rockers.
I'm useing my milodon gear drive, and a 10 qt oil pan , 2 inch x 3.5 headers tuned to 42 inch length. Msd crank trigger with a 7al2 box, probably an Indy intake with a 9375 dominator, or a tunnel ram with 2 750 holleys.
4500 converter, with a 456 dana and spool hooked up to 14x32x15 rear tires, along with a ladder bar set up. 3 inch exhaust
I believe this set up should net me close to 625 hp or so. Make a good little street/race car. I have my race car almost done now, so I am not going all out on this.
Sound like a good combo?
