As far as caddy's go, nothin beats house pulling torque just off idle. Theres prob not a big block stock for stock that can keep up with a caddy motor

That is not exactly true. Pontiac motors looked the same from the outside but there were two series of blocks. Small journal (301, 326, 350, 400) and large journal (321, 389, 455). The 301s of the 80s were also called a "short deck" engine because the deck height was unique. Sorry for the useless trivia.

That is an understatement. my 455 pulls 587 ftpnds at 2900 rpm find a 350 that will do thatt at that rpm. If you do it is rare and it has alot of money in it.

he was plainly talkin smack with the pathetic brand loyalty crap.
That, or has NFC what torque is.
GM built all kinds of good truck motors. It's just too bad they left it to us to place them into the truck.

Grab one of these big blocks... you'll never want a tonka toy 350 motor again.

At one time or another, just about every make of G.M. V-8 has been in a G.M. truck, except for Cadillac. As mentioned here, G.M.C. used Pontiac V-8's in light and medium truck from '55 to '59. Some G.M.C. heavy duty 550 and 600 series trucks used the Oldsmobile 370 during those years too. Chevy used the 322 Buick 'Nailhead' in their first heavy duty tandem axles trucks in '56 and '57, before the 348 'W' Big Block came out. Both Chevy and G.M.C. used the Olds 350 diesel from '78 to '81.

1967....For the Camaro.

IMO, GMC had better options for a true truck engine than Chevy offered.

I believe I said this on here before, but a guy who was a big wheel at the largest local GM dealer in the area back in the 60's and 70's told me a few years ago that you could HAVE gotten a V-6 in a pickup until 74 or some time there after if you had the right connections at a dealer, he never said what V-6, but I assume it was the 305E(Or the last version of that CID)............Whether it was true or not I don't know.

He said they were also playing around with Diesels in our body style trucks in the last years of production, never did say exactly who or what got them, Test beds for small fleet like railroads and others maybe? He liked to chuckle at how bad the Toroflow V-6's were, junk steel in the '73's and up, and who could forget the Chevy Luv

Old Howard lived across the road from one of our farms and loved to walk over and talk trucks...........He was really fired up about the Cummins transplant, sadly he didn't live long enough to go for a ride.
