Olds 350 in 85 Cutlass?

[Chet Who?]

Any one have any ideas bout swappin a Olds 350 into 85 Cutlass? Pros Cons? :?:

I have a 71 Olds 350 rocket in my 87 Cutlass and love it. Pro's. You can say you have a rocket under the hood. Being different and not having a chevy in a olds. Block are realy strong 76 and under and way less than chevy. Cons is performance parts are more expensive. Parts are harder to find, but i have found everything I could need between ebay and online performance shops. Here is a pic of mine after I just got it in.

If you have a 307 now its a drop in. All the brackets AC etc bolt right on. etc etc etc

pros: motor swap is gravy. Pretty much a bullet proof motor. I personally think that they run better stock than a stock chevy 350. Plus... Now you can say that you have a "rocket 350"

cons: performance parts are fewer and a little bit mor pricey (not too bad though)

Sweet! even the motor mounts line up? I pulled the 307 out after 200,000 miles of service. She did me good but now its time for some power. Also what are the options for exaust manifolds? Will full size headers fit in the sweet beast or is it shorties?

There are several aftermarket companies who make headers for the 350 Olds in a G body. If you want to use manifolds for some reason then you can use your 307 manifolds and bolt your original exhaust back up. Oldsmobiles really wake up with headers though.

All Olds small block motors (260, 307, 330, 350, and 403) are externally identical. Use the 307 motor mounts and the 350 will fall right into place. One thing to watch out for is the water pump length. Olds used three different pump lengths and the pump, brackets, and pulleys all need to be used as a set. Just transfer the 307 pump, brackets, and pulleys to the 350 and you'll have no problems. Also, be sure to reinstall all the spacers under the PS pump bracket. If these spacers are not installed properly, you'll never get the pulleys to line up.

That's not correct. The only "drop in" part is the bellhousing bolt pattern, which is the same. EVERYTHING else - motor mounts, frame mounts, accessory brackets - is different. The only "drop in" motor is another Olds motor. The others all fit with the proper mounts, but that's not "drop in" in my dictionary.
