Pontiac engine in a C10

[naphtali5725]

Hey guys,

As you may know, i'm putting a pretty stout Oldsmobile 455 in my 86.

I have an opportunity to pick up a 461 stroker Pontiac built from a 400 block. Should be in the 500HP range with about the same torque, it's pretty badass...

Has anyone ever put a Pontiac 400 or bigger in their truck?
If so, got any pics or tips?

Kind regards

I know i'd like to find an older Olds 350 Rocket ... That block is the one GM converted to make the diesel trucks.

Oh yeah, get you an olds 350 DX block. can get them pretty easy, can build a hell of a motor with one of those blocks. The 455 Olds is bad ass too. I can't wait for mine to be done.

I'd hurt myself with a 455 rocket (just like the police drive) Or a good 400 olds motor my folks had in their 79' firebird.

Also i'm a bit of a noob but found why the SB 400's are tough to find... seems they used to stroke them to 383 and use the daylights out of them.

Of course i may have learned to drive in the 82 but the drivers ed car at my school was a modern front wheel drive ford taurus

I had a 77 c-20 crewcab with a 400 pontiac a few years ago. I didn't put it in, but it looked like it came from the factory that way. whoever did it,did a clean swap, and it ran very good too. about like a big block chevy on the gas useage though. Thanks for your service to our country

YW, I'll probably get it to see how it compares to my Olds 455, should be interesting

Not being familiar with pontiac motors, was/is there something about them that made it easier to drop into the squares? Over the years I've come across more than one pontiac powered square in the wrecking yards.

Back before high performance heads became cheap, and available. The BOP 350's were slightly better starting platforms for performance. Or he could of gotten one cheap.

All GM engines use the rear sump in those years so it wouldn't be that hard if you had one lying around.
