How much H.P. would a set of headers give me?

OK, thanks.

Now back to your question; Being you say it has modified mounts and I assume that they were modified to move the motor, you might want to reconsider the header thing. There is a very good chance they won't fit because of your motor location.

Are fenderwell headers that close of a fit. I believe the motor was lowered roughly 1/4" on passenger side and shimmed up an 1/8" on drivers side. This is from the schumacher location. Wouldn't i have a little more room as it is a B motor not a RB?
