If there are quite a few people running original B1 headed 451 type builds making more than 800hp, and running like 800hp should in a 3100lb car...... I think it would be in your best interest to chat a few of those folks up and see where they had their heads done.

Why try and reinvent the wheel?

BTW, did you discuss the performance(or lack of it) with Ray?
Did he offer any insight?
