Searched and didn't find much... asking out loud. My '78 400 WS6 has an aftermarket Edelbrock Performer intake and carb (electric choke) and a hacked up drop base cleaner to accommodate the choke. From the looks of it, both have been on for some time. EGR choke stove (?) was blocked and all the emissions stuff is removed. I'd like to go back to a stock Pontiac aluminum intake (i.e., 1971 H.O. like for sale here: https://www.ebay.com...353.m1438.l9372), but I'm a bit unsure of what carb to use, or what other options are available to me. Are there aftermarket carbs I can use on the H.O. intake, or am I better going w/ a rebuilt Quadrajet w/ electric choke conversion? Or throttle-body EFI? Aftermarket carb w/ a spread-bore adapter? Biggest consideration is I want to keep the shaker and I don't want to affix it to the hood just to keep it. What are my options? I'm not looking to race, but I'd like to optimize available HP and torque I know stock Pontiac parts provide over aftermarket. And where the car was a factory 4spd someone replaced at some point w/ a TH400 AT, just picked up a Super T-10 out of a '79 T/A in good condition. All opinions/insights/advice appreciated... and tracking I'll need to block the exhaust ports the factory cross-over would attach to since it's likely not needed w/ the electric choke or EFI.
