View Full Version : Vintage Chevy V-6?

Anyone know what engine this is? Saw it in a 71 GMC 3/4 ton 2wd. Never in my life have I seen one. Says GMC on the V/C's, 6 plug wires and spark plugs on the top of the head. The valve covers look like a 409, but I counted the wires and dist cap 3 times and it's a 6!

I believe the 67 to 69 Firebirds had a factory V6 option. I'm guessing someone could have special ordered the pickup with one. Unlikely but possible.

Some older US pickups had the V6 in them, sixties for sure, maybe even fifties.

That is a GMC 305 V6. Available in US GMC's only. I am not sure if it was available in 72, but for sure 47 to 69.

Sweet! I figured you guys would know! [cheers] Pretty rare engine, and I guess the truck could have been a 69, should have taken a pic of it.

Nelson Car show in Early Sept. Just hadn't seen this variation of V-6 before. Would love to own an early Chevy, just need more time on my hands! :)

You ever sell your early '70s Chevy? Saw it on the highway last year coming home from Trout lake.
