Hey guys any help.....i have a tri-power manifold that is casting number 3749948, GM-2, K2458, can anyone tell me the year and what it is for,,thanks :confused:

There are only three trip intakes that are stock, a large oval and a rect. port BB motor and a 348 "W" motor!!

I don't know if Mortec has an intake manifold number section or not but I can also look through my stuff a little deeper and get back tonight..

thanks for the quick reply's,......

Wasn't there a stock pontiac Tri-Power also?

Pontiac 1957-61(?), GTO's (of course!), Cadillac (late 1950's), full size Oldsmobile 1957/58 J2 and J2R, Olds 442, 58-61 Chevrolet 348's to name a few.

'67 oval port, '67 rectal port, early '68 oval, and rectal, late 68 and '69 oval, and rectal. Six part numbers for the tri-power Chevy 427 alone.

And the, rare as hen's teeth, one year only '66 Olds 442 trip's too!!

PS., and I wasn't going to get into other GM trip intakes OR part numbers and years!!

Back again, AND Smokey had a stock, one-off FACTORY SB Holley trip set-up at one time in his collection of rare stock parts...

Talk about rare!!!

I know a guy that would give a pile-o-dead presidents for one of those factory small block tri-power intakes. He claims there were 8-10 of them made when Chevy was doing engineering work on the Trans Am Camaros.
