I am purchasing a low mile 85 Buick turbo v6 long block. I will not be running a turbo with this engine. Just some head porting, cam swap, new oil pump and gaskets. I will be using a Holly 390 cfm
and Edelbrock intake.

I believe the 85 turbo was a distributorless ignition. Does it have provisions for a stock distributor?

What are the stock cam specs on the 85 turbo engine? Was this a roller cam?

Thanks!

There is a port in the front for a distributor. the turbo cars had a cam sensor in this spot. These are also hyd flat tappet cam engines. Don't know of the stock cam specs.

GM just stuck a distributor like cam sensor in the turbo versions of the Buick V6. You can just simply swap it out for a normal distributor. The n/a versions of that time still used distributors. There is also a oil return hole in the bloch for the turbo which will need to be plugged.
