I'm thinking of running straight LPG on TB42 with Gas Research mixer. Am I better off using the carb manifold, which I've got, or the EFI one? EFI one looks like a better position for mixer and intake plumbing, due to direction it faces and space above motor. It would sit in place of throttle body, which is where I would have mounted the mixer on carb manifold setup. What's EFI manifold worth anyway?

I would just keep it on the carby manifold if thats what it was designed for.

Just make sure you get it tuned properly for best results, preferebly an LPG shop with a dyno. The GR mixers can be difficult to tune, but once set up right they are tops.

running gas off a carbi manifold to definatly easier and the way to go.
you wont look back

I would go the efi manifold if its cheap, as long as its tuned length / plenum chamber. better for mid range torque. also compare an efi throttle body to the carb throught size. chuck the carb manifold in the bin.

whats the gas research setup worth roughly for a GQ?

Speak to the gas research guys themselves, last I knew (a while ago)
they were in Frankston-Dandenong rd. Other wise try Lakeside automotive in Resivour. Shane Baxter there is a drag racer who knows his stuff, and you need to dyno gas research... he does it

i'm running gas reseach on my 350 chev, it been great so far, plus it can keep up with the high demands of gas under full throttle which is nice
