Hello guys,

I have got a question about the whereabouts of a spot to pull a vacuum for a power brake conversion. It's a performance online kit. Obviously it needs a vacuum, I don't know where a spot to pull a vaccine is. Thanks guys.

I have a ramjet in a 67 Camaro. I can't remember where I pulled vacuum from for the brakes but I'll check when I get home in a few and upload a pic. Oh, you're going to love that motor.

Here you go. Works great.

Thanks a million. I'm starting work on the conversion tomorrow and. I would have looked high and low for that thing. Have a good one!

I love that ramjet set up. What is all involved in installing on a 350?

Most times it's part of a crate engine,

but g.m. did sell the efi set up..

The crate engine is a 1996-2000 vortec truck engine, with that stand alone engine management system.
A different roller cam, 1.6 rockers and 330-340 hp..

The Efi alone was a tad pricey..
Edelbrook makes one, and most likely is about the same .
and isn't cheap..

the g.m. efi requires vortec heads..

Thanks for the Info James.

Yeah, I guess it must be a volume thing, but:

- Cast aluminum Holley carb intake: $99
- Cast aluminum Holley EFI intake: $999
