A Cutlass is a montecarlo made by Olds basically.Its a G body.
If its got a V8 Olds(307)in it now just a motor mount move and all the bracketry and pulleys and exhuast manifolds for a SBC is needed.Also emmisions stuff for A SBC,if nessesary.
If its a V6 now then you'll also need new front springs and an alignment.
Thats basically it.

Slam dunk, easy swap. If the car has a 6 cylinder in it, it`ll involve a little more work but not much. if it came with a 307 olds engine it`s almost straight forward. You`ll need small block chevy mounts which bolt right up, just get mounts for a 87 monte carlo with a small block. V8 cutlass has fuel lines on passenger side, makes for easy hook up, V6 has them on drivers side, so some fuel line routing will be called for. V8 has battery on drivers side, so again, some rerouting is needed. V6 is on passengers side, straight forward. if it has a V6 you`ll need a V8 cutlass crossmember, which lines up perfectly with a TH350 short tail transmission. If it has a V6 I`d recommend V8 coil springs for your own safety. Also if it came with a V6 you`ll need the V8 radiator, clutch fan, and fan shroud. You`ll have to get some exhaust work done. you`ll need to take the time to seperate the computer wires from the main wires, the computer wires will be all on the passengers side. Seperate and mark the temp and oil pressure wires off the main side so you`ll know which is which. one thing to remember, if it`s a V8 car, there`s a fuel vapor/vent line that runs to the carbon canister, that will be sitting in the battery well on the passengers side, since a small block chevy has to have the battery on the passengers side the carbon canister has to be removed, so the vapor line will have to remain open, if you cap it off, you`ll have nothing but endless fuel pressure problems, solution here is, cap it off and run a vented gas cap. one final tip, I`d run a ground from the block to the frame, just clean the frame and run a ground to the bolt that holds down the brake line on the back of the frame under the engine, then after the engines installed, run a ground from the block to the frame, this will help alot if you plan to use headers, and even if you don`t run headers, it`s still a good idea. make sure you reconnect all the factory grounds as well.

Hey I have a 1986 Olds Cutlass with a 307. Will the transmissions that came with the 307's from factory bolt up and work with a sb 350?

I would really appreciate it for that info.
Thanks,
Chris

Some of the Old/Pontiac/Buick trannys have a dual pattern that will fit Chevys too..............you will have to check. If not, a Chevy tranny will bolt right in with the Chevy motor. Other than the bolt pattern, they are the same.

there is also an adapter plate that you can buy from most places e.g. JEGS for about 45 dollars. that should be fine unless you are building up a powerhouse.
