Engine build help

IIRC, this engine was bought rebuilt, wasnt it? Maybe I'm confusing it with another...

For a 2900lbs tire and exhaust limited car, I dont think I'd be building a stroked version. I'd be building a higher horsepower vs torque engine. I'd use the same pistons, to avoid having to bore the block and buy new ones. Just run a quick deglazing hone thru it. If it's only one throw (1 or 2 rods) there's a good chance the machining or clearances were off. If all the rods show signs of heat or oil starvation, or detonation (you can have it, and not hear it) you may have oiling problems. I'd run a forged crank, and replace the rods with decent H beams. Have any rods cycled and inspected for roundnesss and taper. I always stud the mains in an engine that is expected to go over 5500 rpm. If you are not running the newer heads now, I wouldnt build the short for them. Just build it for the 906s and steel head gaskets. Then, when you go for the better heads, you can just bolt them on and go. IMO, the Indys are too large a port even in the std port SR configuration for under 470 cubic inches and peak power below 6500. I'd recommend Edelbrocks. Make sure the block gets cleaned out..pull the cam bearings, that kind of thing... Get all the shrapnel out.
