I think you need more cam, that cam is smaller than the factory L88 cam from back in the 1960's. I don't know what the HP is but we're running a .660/.654 thumper in a 468" same compression pump gas and it's pushing a 3700 lb plus 66 Biscyne less driver to 10.56@127mph. it is a solid roller cam though and we're running a 1050 Dom. It's been 6.23 @ 108 & 10.13 @ 131.82 with a 150 shot. It idles @ 900 rpm
