Holley makes a 400 CFM two-barrell and a 300CFM one-barrel. These are replacements for GM throttle bodies. I don't know how either would work with a stand alone system.

I'm using a GM two-barrel TBI and GM computer on my 200 with Aussie head.

Do you haver a log head or other? If its a log head i would go with the 300cfm 1bbl setup. If the answer is other I would go with teh 400cfm unit.

Take a close look at the one for sale on Jeg's: It's a 2BBL, but it's designed for use on a 4BBL intake...it might not fit any known 2BBL intake patterns.

Harrie, have you changed your mind on the MS?

I looked at the system. It looks very interesting. It is a 2V. It is just bigger then a standard 2V. There are only 2 tunnels on the botton of the TBI. It looks like you may be able to weld up two bolt mounts and just custom make a gasket and it looks like it may fit right over an Aussie 2V.

I looked at this...but I'm going a different direction now...hehehehe

Regarding flow rates-

My understanding is that the reason you don't go too large of carburetor flow rates is that the vacuum signal is too small in transition from idle to mid-throttle. Wouldn;t taht condition diappear with a properly tuned TBI?

My understanding is that the TPS is only used to determine when the car is at idle, and signal the rate of throttle opening so the ecm can fire the injector the appropriate duration.

Or do I once again have this all screwed up?
