Stainless Marine BBC dry flow HP Potential
 

I tried making a thread on the various Stainless Marine Generations...and guys were mentioning them in conversation.

I have Stainless Marine manifolds, risers dry to tip. (1/8 muffler cooling weep holes top am bottom.)

These are from 1992 ish. What is the HP potential without a restriction becoming a factor to contend with?

My current plan is 650-700 with 454s & 420s with some mold port work on the 088 heads.

Thanks,
