[SEL] 454 engine specs. and OT

[Jeff Allen]

Hi Bill,

Quick rule of thumb from someone that does this for a living. The wanna 
be mechanics and the ones that didn't make it can chime in later. Never 
bore over .030 on the cylinders, and even then you can have heating 
problems. You can get away with .020 on the crank, but I prefer no more 
than .010 under. Stock 454 is one cheap horsepower engine, and the above 
limits should work fine. Add $5000 and you'll be in the 500 c.i. range 
with custom cranks, etc. Glad to help more off list if you need. The 
above limits are what I use and the engines live.

Custom turbo Corvette, 7:1 turbo pistons, and it put you sideways when 
you hammered second gear. Been a day or two but I can still drive em and 
counter steer when they want to swap ends. Yi Haa!! Gettin to old for 
that sh*t. I think my recommendations are good.

P.S. off list, whats it in?
