Thanks, John. Those ARE impressive numbers. But
ya gotta admit, those hemi numbers look good too,
especially from a fifty year old motor! And, I
can buy six hemis for the price of a set of those
Brodix heads. Hee hee hee But, I gotta admit, I
didn't think the SBC (Even Brodix) flowed that
much. Those would be just about the most one
could expect to get from a SBC, wouldn't they?
