Straight six vs V8

Hi I have a 64 Pontiac stratochief with a standard straight six and I'm contemplating on doing something different and putting A high revving kit on it and super charging it.. Would this be worth while or would it be easier to just put a krat motor in.. Thanks

Might be the 230. I don't think I've ever seen one like this. Canadian, maybe?

I think it's cool you are thinking about doing something w/the six. A list of sites for the inline 6 is at the bottom of the post. Besides working w/the inline, a couple thoughts come to mind:

You could easily install a 400/455 Pontiac along w/a TH350 (I'm guessing you have a 'Super Turbine 300' 2-speed automatic in it now). Using a V8 donor car would make this easier, but that's asking a lot.

Swap it out for a Sprint 250 cid OHC Pontiac engine. I have first-hand experience w/this little jewel, it's a runner. But it will want a bit of rear gear to get that big car off the line. It would bolt right in place of the 230 in there now- same motor mounts, etc.

The downsides are the OHC bellhousing bolt pattern is the 'BOP' type, so won't mate to the Chevy pattern transmission (unless the Canadian Pontiac/Chevy inline 6 engine has the BOP bellhousing bolt pattern). But you'd be better off w/a TH350 anyway. The CR of the 4-barrel Sprint engine is 10.5:1 advertised, likely about 10.2 in reality, but still too much for my tastes. That means either getting a 1-barrel engine and install the Sprint intake and exhaust so you can have the Q-jet, or dealing w/higher octane fuel. And it's down on torque to a V8 and torque is what that car wants.

Lastly, a Chevy will fit, sure. The mounts, etc. can be sourced from a B-body w/a Chevy V8 from the same era. I think some '65's had the BBC 396 but if going to a BBC I'd go w/a 454.
