What about the balance of fuel MPG and torque!?.... in other words take a sbc 327 ...just by changing cam I can get better TQ and MPG.
What size motor to build!?

: 1600, 1641 !? ...piston and cylinder kits , which and why? ...or even bigger 1776cc, What do ya think! What about the balance of fuel MPG and torque!?.... in other words take a sbc 327 ...just by changing cam I can get better TQ and MPG.

Check over in the newbie forum, there's a sticky about how to build up a high output 1600, bigger isn't necessarily better.Beezerbob wrote:: 1600, 1641 !? ...piston and cylinder kits , which and why? ...or even bigger 1776cc, What do ya think!

IMHO having the fins on the cylinders 'aluminum-sprayed' is well worth the bucks for the additional heat rejection.
My slip-in 88mm jugs were sprayed, & it dropped the engine oil temps by 30 degrees Fahrenheit. CR is set at 8.2:1, with just the combustion chambers polished; runs fine on regular grade unleaded. Same thing is supposedly true for even a stock 1584cc motor.
Substituting Kadrons for the stock 30PICT-2 lowered the temp a little more, plus they give better fuel mileage and, of course, more power. (they actually lowered the emissions, but they weren't smog legal!) City: 18-21mpg. Highway: 22.5-26.5mpg.
CDI ignition always fires it right up & gives it 50K mi spark plug life, and drops the ignition point current to a few microamps; ie. no point burnout, just lube the rubbing block once a year.
YMMV!
