Doug Mitchell Posted August 28, 2020 Share Posted August 28, 2020 I have a 1970 with big block 402, thinking about changing out the factory quadrajet to an EFI system (Holly Sniper), or is it maybe just as good to have the quadrajet rebuilt professionaly, i have rebuilt it myself a couple times over the years?

1Bad454 Posted August 29, 2020 Share Posted August 29, 2020 Fuel injection is a really nice thing to have. Easy start up all year around and quick throttle response. I too am looking at the Sniper unit. Quote Link to comment Share on other sites More sharing options...

714024SPEED Posted August 29, 2020 Share Posted August 29, 2020 I have the MSD atomic EFI on my wagon and love it . Nice thing about these kits is when you have an air cleaner on everything looks stock like a carb. 1 Quote Link to comment Share on other sites More sharing options...
robbo Posted November 22, 2020 Share Posted November 22, 2020 My recommend to the Edelbrock system. I too plan on that system vs Holley Sniper. ROBBO Quote Link to comment Share on other sites More sharing options...
wallaby Posted November 22, 2020 Share Posted November 22, 2020 Power output is the same. The EFI gives benefits at startup, or altitude changes, that a carb can't match. There might be a slight improvement in mileage with EFI, but it's not enough to consider. FYI Quote Link to comment Share on other sites More sharing options...
