850 cfm proform carb on 318!!!!

Yes ol-kim, small potato's and no help.

T67, yes and no and heres why.


First up, it is a build dependent item.

2nd, it's a area where a larger carb could stink on the engine. You allready descriobed certain things about the engine that can have this work.

However, things like stock stall converter and a 2.76 rear gear etc.... would have this a real pain to tune in and work well. While possible, it's hard to get a 850 to work. I have and I didn't like it much. Then again, my stock verter & 2.76 gear were not helping the issue.

David Vizards results are acurate. This I know first hand before I knew who he was. BUT, the engine and car set up has to be able to handle it first.
