Well i thought i had a local guy to convert my intake for my 383 but he just informed me he cant do it. So im looking online and see a few companies who can do this but i dont know one from the other. Has anyone had this done? Where did you take it/how much did they charge?

Thanks
Ryan

I have some universal weld-in fuel injector bungs and some bulk fuel rail that I won't be using if you're interested. If you drill the intake yourself for the bungs, or at least drill the pilot holes, a fabrication/machine shop could weld the bungs in for you. The fuel rail is a long piece you cut to length and drill the holes for your injectors.

There are some companies including a couple board member who can convert an intake for you start to finish. I think they charge around 350-400 bucks for this service.

Fast Man EFI Rich can do it. Its typically $300 or so...You can go the EZ efi route and just bolt it on if you prefer a carb style intake without the hassel...

IIRC Board member Jerry used to do it, might want to PM him

Do it yourself. Pringle did, as seen in this link.

I've converted a handful of iron intakes with brass fittings as an R&D thing. If you have a drill press and can fabricate a drilling guide jig, you can drill/tap fittings into the runners if you're patient and think a couple steps ahead.

A 3/8 NPT-5/8 tube union adapter works well (the 5/8 end fits an injector O-ring nicely) or you can install a pipe plug, drill it, and finish-size it with a $20 ream. Buy a set of Eddy rails to use as a spacing pattern (you'll need rails anyway).

I haven't run mine on an engine yet, but I made some block-off plates and pressurized the intakes to 60 PSI and they sealed perfectly. Used red lock-tite on the threads of the fittings to seal them.

You'll probably end up spending $75-100 on tools & supplies, so it might not be worthwhile if doing just 1 intake. I had a stack of intakes to play with so I went to town.

I have a handful of pics and a logbook of all the tips/tricks I learned, if you want to head this route send me a PM.

Thanks for all the help! looks like i am going to have Jerry modify an intake for me. Now i just need to find a single plane intake as i just have a holley street dominator.

Street Dominators with which I am familiar are all single-plane intakes.

Shoot even better. I've had one turcked away for a while now and guess i just had it stuck in my head that it was a dual plane. Thanks!
