Holly or 454 TBI?
Hopefully this summer I will modify my engine enough to top 300HP, I was wondering which one of these two units are superior?

Where did you get the 454 unit from,
(showing my ignorance here) since the 454 is a BBC, will it fit a SBC well due to the different intake manifold size.

it wont fit on the stock intake because of the bigger 2" bores. however it will fit on a atandard SBC carb intake with an adapter.
