New to this Forum

Howdy from Canada - I just came across this forum and thought I'd take a look. I love to modify my vehicles to improve performance, handling and looks, so this forum seems to be right up my alley. I just got my first Corvette. After lusting after a C2 forever I found a 1967 L-71 coupe in pretty much original condition that has sat for years, so am now working on sorting out the bugs and getting it back on the road. The tri-power carbs are proving to be a bit problematic, but I'm making progress there. The big problem is that a PO installed a cam that pulls very low vacuum and sounds like a top alcohol funny car at idle. I suspect big overlap, but have no specs. This will probably have to go to get the tri-power working right. Anyway, glad to be here and looking forward to exploring the forum!! Cheers. STEVE

welcome

If anything, the tri-power would make the cam liveable. The problem with a high-overlap cam is it doesn't draw much vacuum at idle, thus it doesn't create a great signal to draw fuel in - the larger the carb, the worse it gets. Tri-powered carbs are essentially 2 barrel carbs. With the progressive linkage, the engine, at idle, is only pulling off the middle carb. Because it's a small carb, it would actually be pretty good at dealing with the issues of a large cam.

Brakes would be an issue if they are vacuum driven. Find someone who knows how to tune tri-power setups in your area. That said, someone drove it that way before and is likely it drove fine. If it's not running right, more times then not it's a spark issue - especially in cars that have sat forever. Whatever you do, before you start messing with it - be sure you photograph, diagram, and measure the adjustments for the progressive linkage.

My '72 is completely not stock, from wheels through roof....

see sites below for a hint or two....:crutches:

Welcome! :hi:

I just did a 2x4 setup on a 270HP 283 w/3 speed in a C2, and last Saturday we did a rear main seal and a tune up on a64 GTO vert with a 389 tri power and a 4 speed... the factory 2x4 setup on that 283 was way better than the 389.. that said the tripower was easily set up...
