Given your cam and heads, those numbers aren't too far off what I'd expect (and the difference could just be weather...)

A TR224 is really really small for those cubes. The 215s are probably too small as well.

On my 427, I'm running a 237/246 with 245cc heads.

What did you do for exhaust? You'll want 1 7/8 long tubes as you start opening up the intake.

All of those things will push your power up, but that 60e will start being your limiting factor.

How is your oil consumption?

Was going to install vindicator camshaft but found one worn out cam lobe.

PS LT headers with PS ORY pipe, 3" tailpipe and 3" flowmaster muffler.

It's only 100 mile. Will keep an eye on oil level.
