    Funny story: I bounght a 79 k5 over the summer. They guy i bought it from didn't know what engine was in it, "something pontiac i think", Well i got it cheap and had an engine lined up to swap it anyways, so i bought. Pulled it out it was a ponitiac 301. Biggest POS i've ever seen. anyways, it's not every day that you seem that so i thought i's share.

    Man! What the hell was that guy thinking? Those 301's are dogs! I wouldn't want one of those in my lawnmower! Glad you've got another engine for the K5!

    Yes, as a Pontiac Man, I would agree the 301 is a dog. They had siamesed intake ports and very short deck height. Now, if you wanted to swap in a good motor that would out pull any Chevy smallblock - install a 400 or 455 pontiac. I used my engine dyno program and tested some pontiac engines. I had to put tons of dollars in my smallblock to equal the torque of a junkyard Pontiac 400. In most cases, the pontiacs even out torqued the famed 454. Pontiacs are usually easy to get ahold of. That reminds me, maybe I will pull out my 400 SBC and install my 1969 428 Pontiac - 360 Horse motor with 10.75:1 compression - stock. I wonder if I can get a 4bbl TBI system to work. I could slap a set of those Wenzler High Port heads on there and make tons of power! Check out Jim Butlers site, his sons have 7 sec 1/4 mile Pontiac powered cars without nitrous! Thats awesome for the "old" Pontiac block design!

    here are a couple of Pontiac parts sites:

    I always liked the 400's and 455's, I had a friend with a 75 Grand Prix, what a torque monster![​IMG]
    How do you get around the BOP bellhousing for a swap? Or do they make adaptors? I'm looking at either a 383 stroker in the next couple of years or maybe a swap of some sort and the Pontiac stuff has always interested me.

    tRustyK5, they make adapters that go between the engine and tranny to adapt the BOP pattern to a Chevy bell housing. Just about any adapter place should carry them.

    A buddy of mine has an Olds 455 in a Wagoneer. OHMYGAWD it boogies! [​IMG]

    I hear that, Mudzer. I'm a Pontiac man too. Poncho's have to be the kings of torque. A friend of mine says that Chevy makes HP, but Pontiac makes torque! I'd put a Pontiac engine over any other in any of my vehicles.

    About those adapter plates... i forgot the end of the story earlier. I was taking the blazer up to a friend of mines garage. THe thing had been making noise like crazy, i thought it was the transmision( i had just had a rebuilt done on it) Anyways, we pull the 301 out, the extra gap the adapter made between the torque converter and the flex plate had caused a lot of stress on the bolts. The Flex plate had spider web cracks all between the bolts. It was so bad that it only took one blow from the hammer to knock it off, with out loosening the bolts. So i'd watch out wih the adapter plates.
