What is the compression height of a low-deck 383 with a 7.10" rod? That's a 2+ rod ratio, which is uncommonly high. (We're still talking a 3.375" stroke, right?)

Got flow #s for the heads? And are they standard port or MW?

What's the induction system?

What sort of RPM are you spinning it?

Auto or stick? How much stall, if auto?

Regardless, it hauls a$$ for what it is.
