1969 383 in a 91 RS??
I have a 350 4-bolt main out of a 1969 Impala. I am planning to make this engine into a 383 stroker. I was wondering if the engine mounts would match up correctly. I will be bolting the 383 up to a 700-R4 transmission. In addition, I am planning to put a 750 Holly Double Pumper on the manifold. Will I need to buy a special type of wiring harness to ensure the carburetor will work?
Thanks

The engine mounts are the same, but the flexplate is different because of the change in the rear main seal.

You don't need a "special" harness, but you will need to modify what you've got slightly.

Thanks for all your replies; I just have a couple more questions. What is the best type of flywheel (brand) and what modifications should I do to the wiring harness?
Thanks again
