Hey all,

I have posted on this project recently and it seems like no one else has or is running the Edelbrock EFI proflo setup on anything, probably because it's an older efi setup. Anyway, it's what I have and had run for 15k miles and 15 years on my 383 and I'll never go back to a carb. Can't afford a whole new efi setup, so I am modding what I have.

Basically the motor is a Dart Little M 427 sbc with AFR Eliminator 210 heads and a solid roller cam, 630/630 252/258 dur 111 LS.

Anyway, the motor is getting finished and I took the intake setup to them today to check the port match and the AFR head intake runners are so tall that the intake, which is based off of a Victor Jr. won't even seal, much less match up. Of course with my hundred questions to the Edelbrock efi tech line, this never came up...

So they are having to add metal to the top of each runner, then port the runners and the plenum. They say that getting it to flow enough for 600 hp shouldn't be a problem, but I'm looking at $500. There is no other intake or Throttle body I can use with this setup because the TB bolt spacing is odd and additionally requires a unique throttle position sensor (among other things) that prevents me from doing any parts swapping. The Victor EFI intake won't even work.

So here are the EFI mods I will have h ad to make.
1. New 48 lb (Venom) injectors=$400
2. New chip for the longer duration cam=$50
3. Port work on the intake = $500
Total approx. $950

Clearly this is still way cheaper than going with an entirely new EFI setup, but it is still pretty expensive for a fairly primitive system.

I'll post some pictures of the welding/port work if I can before they put it on the motor if anyone is interested.
