Im swaping in a 77 olds 350 into my 86 cutlass that currently has a 305 what will i need to mount the engine, can i use the engine mounts from the 77 cutlass the engine came out of? Will it bolt up to my th200 r4 or am i going to need an adapter. Any help appreciated
Welcome to the group... The 77 - 350 will bolt up to the 200R4 without an adapter... However the function of the 200R4 will depend on how much of the electronics you keep...
As for the frame mounts you may need to change to the 260/307 frame mount as shown in the photo below...
To clarify, it's not "may" need to change the frame mounts, it's definitely. Those mounts were used on every 78-88 A/G-body and every 77-90 RWD B/C-body car with an Olds motor, so they should be easy to find. Note that they are slightly different RH/LH, so take care when installing them. Use Anchor P/N 2328 motor mounts to match. Also, those frame pads do not bolt to the same holes in the crossmember as the Chevy mounts, so be sure you get them in the correct location. Obviously all the accessory brackets, hoses, exhaust, and wiring changes for the Olds motor. Starter is on the other side of the motor, for example. These cars came with the Olds 307 from the factory, so with the right parts, this is a direct bolt-in.
