Pontiac Xram SCCA engine

[tjs44]

I have read much of what is in the article and have read about the 366 short deck engine but have never ran into any of those parts over the years.The short deck block used 2.5 mains against all the others being 3 or 3.25 mains.I have owned and run into many 366 std deck parts and engine.Never talked to anyone that had there hands on the short deck 366.I actually built one with a 303 short deck block,a 57-58 forged crank and custom internals.Tom
