Question about tri-power for Grumpy ??????????

[1stvtt1981]

:?: Grumpy, Your tutorial, "a trend you'll eventually notice", is a real nice piece. A lot of valuable info, as were the links. A quick question for you, if you don't mind. I was talking with some GM Geeks and the question came up: Is it possible to put tri-power on an 81Corvette 350? No one had an answer,
so I thought of you. I personnally can not ever remember seeing one, but I only just got my first Vette.
I thought perhaps the heads might be different. Larry 1stvtt1981

but a couple 450cfm or 500cfm dual quads are usually easier to tune and tend to work better in my experience than old rebuilt Rochester two barrels

the offy intakes still available, just be aware it takes a high compression ration and a fairly long duration cam with matched gearing to match the x rams flow and rpm band, youll want a 355-406 duration and a cam with about a 250 dur at .050 lift and 12.5:1 cpr with a 4.11 rear gear to get into the ballpark
