EFI 101: What to Consider Before Switching from a Carburetor to Fuel Injection

[@ericspears2228]

I have installed an aces fuel injection killshot unit and have not regretted it. Been over a year on my truck and way more responsive and efficient.

Enjoy Justin, like to see him take 57 body parts that Summit Racing cares and install them with Robby Layton.

I have a 57 Chevy with a 454 big block, stock fuel tank, a Holley blue fuel pump, and pentronix flamethrower distributor, the cam is a 569 lift roller, could I use the efi Holley sniper 2, and use the non return system you mentioned, some people tell me that it won't work, thanks for the infro.

Good job Justin I’m curious if anyone out there has switched from Holley carb on a 80-86 F-series 351m to injection…? Was it worth it ? Better mpg? Better hp?

Add on fuel injection system does not necessarily make more power can increase efficiency YES but not necessarily increase power its these videos with comments like these that make me avoid certain suppliers.

I've herd the conversion is illegal however how would they know if you have it and why would it be illegal if it's reducing emissions??

Will be building a 496 bbc with 10.5 compression for single turbo for street and sometimes track. Looking for the best approach with 1400 hp

Carburetor is better! It's easy to tune, makes great power, and no computer is needed. 💯

I have a 73 Ls4. Will a EFI help efficiency? Could a 10% or more gain in fuel economy be seen?
