The Holley Sniper is good for up to 650 hp so no problem supporting your engine. There are a few different Sniper models so you just have to figure out which one you like. The Stealth model looks like a carb and the factory throttle linkage will line up properly. The square Sniper is wider than a carb so the throttle linkage has to be adjusted. I highly recommend adding a Hyperspark distributor so the Sniper can control timing. The 12-319 drop in fuel pump module is the way to go. It makes the install super easy.
