[64 cutlass]

I have a 64 cutlass with a 330engine with a 2 speed auto and want to put a chevy big block with a chevy turbo 400 in it. Will big block frame mounts from a 65-67 chevelle work ? chevelle headers fit ? can i use my olds trans crossmember ? will i have any clearance problems with firewall or heater box ?
can i still use my console auto trans shifter with the 400 trans. and will the turbo 400 fit into the trans tunnel with modification.

any help would be greatly appreciated.

A few things to think about, I think the mounts work, and no clearance problems, the headers not sure, the crossmember might have to be moved and the shifter is only for a 2 speed so won't work, but the t 400 will fit no problem but won't bolt up unless it is the multi fit bolt pattern. I'm not sure on drive shaft length comparing the lenght of the powerglide to the t400. I'm pretty sure the splines are diff so maybe you can get a proper length yoke for the t400 to correct the shaft. Good luck.

Why is it everyone automatically thinks they have to stuff a Chevy into..... whatever they're driving. If you want to really improve your F-85 and don't want to lower the resale value why not stick in an Oldsmobile 455. Right around 400 hp bone stock with plenty of potential. Plus its almost a direct bolt in. If you do that, at least you won't be driving another cookie cutter Chevy powered yawnmobile.

All that said, its your car.... do what you want.

I have done this similar swap. Many years ago I had a 65 442. The Olds motor came apart at about the 1000 ft. mark at the local dragstrip.

It was cheaper to build the more powerful BBC. The difference in build cost, plus sales of the Olds parts, almost paid for the mounts, headers etc.

Use Chevelle frame mounts, headers, engine accessories. The trans crossmember/frame. Has several holes in it and can be moved to fit whatever trans you install. Driveshaft will have to be made/found.

Olds guys will hate you. I drove the car for two years, got WAY more for the car with the BBC in it!!

i'm a chevy guy, and most of all, a big block chevy guy.
but that being said, if it was my car, i would also put a 455 in it.
keep its blood line pure, dont make it a mutt.

And that's the #1 reason to go with a Chevy engine; cost. As for the shifter; if it's a console you can convert to a B&M or you can get a column conversion from one of the suppliers like Year One or National Parts Depot.

If you're going racing you're probably right. However, for a street car there simply is no reason to homogenize a perfectly good F-85 with a cookie cutter BBC. The cost to do a basically stock rebuild is almost identical between the Olds 455 and BBC. Add an intake and carb, cam and headers (which is basically all you need for the street) and you haven't really spent any more than you would have on a BBC..... AND you haven't ruined the resale value of your Oldsmobile.

Olds people are a little like Mopar people. They look for purity of the blood lines and most won't pay good money for one that's been compromised. If you're not going racing every weekend then I say... keep it all Olds.

Hey! There's no reason to be insulting!

Seriously, "bloodline" aside, the world really doesn't need another Chevy engine swap.

ZZZZZZZZZZZZZZZZZZZZZ


Hell, I'd be more interested in a hemi swap than another belly-button Chebby motor.

Hey brother I hear ya I have a 72 cutlass with a 454 I have no complaints I would love a 455 but the cost is very diffrent. The intake itsself is like a 150 more and it adds up from there. I didn't have many issues with mine but its a little diffrent then yours. Have fun it is gonna have a hell of a kick by the way what motor are you putting any specifics are always welcome

[1971BB427]

The machine work on either engine might be the same, but there's no way you can tell me that a 4oo or 455 Olds costs the same to build or rebuild, vs. a 427 or 454. I know from doing both that the cost of a big block Olds performance parts go 2-3 times what a big block Chevy costs.
