just install the Eddie manifold and a small carb and run it. This is a real good choice for a street performance carb:

I personally have had terrible luck with the Skip White HEIs. on other sites they're referred to as the "ebay $50 Fake HEI." I've had 3 of them fail on the first drive, 2 others within weeks. the GMPP HEI often called the ZZ4 HEI is under $200 and will likely last your lifetime. A quality module for an HEI costs more than the whole Skip White HEI. Wonder if that's got anything to do with it. The GMPP unit, buy it, drop it in, run it. Do not replace any of the electrical parts in it at all.
if you buy an electric fuel pump check the output pressure you want about 6 lbs. The GPH flow doesn't matter much as long as it's a 6PSI deal. If it's any more than that you'll have to run a regulator, another source of problems. You don't want one of the $25-35 units from an auto parts store, they're garbage. you'll have to carry a spare with enough tools to change it out if drive it anywhere more than a few blocks.
Really, skip the Skip White HEI. if you do get one of these make sure your AAA is paid up.
