Are you asking which ones to use on the block itself? What year of block do you have. Pontiac has basically 3 styles. The first is a two bolt design up to '68. The second is a 5 bolt design..from '69-'75. Then a 3 bolt design from '76 to '79. I'm going to assume you have a 5 bolt design. You will need the engine mount brackets from a '69 and up Firebird with a Pontiac V-8. It will use 3 of the bolt holes in the block. The upper hole and two of the lower holes. Buy the correct rubber mounts to install on the frame and you are good to go. Hope that helps.

Unless you have absolutely nothing better to do, this is absurd. The Pontiac engine will not hook up to the Chevy transmission. Then the complete exhaust system will have to be custom made. There is hardly anything that will work....... No The Pontiac is carburated, and wont bolt to the transmission, mounts or wiring

Do the front springs and motor mounts need to be replaced when replacing a Pontiac 301 engine with a Pontiac 350 or 400 or 455 engine for a 1979 firebird espirit?
Yes, the 350,400,or 455 will out weigh the 301 by about 200lbs, so the front end will sag under the additional weight. Depending on the year of the motor you are swapping in you may be able to use the stock mounts. 1970-1979 Pontiac V8s had five bolt bosses per side and will bolt up to the 301 mounts. Pre '70 only had two bolts per side making a mount swap nessary.

What needs to be changed when installing a 1990 fuel injected Chevy 350 engine into a 1986 Pontiac Parisienne that has a fuel injected V6?
The bellhousing, the starter, the exhaust manifords, maybe the flexplate (flywheel) and the computer, and probably the motor mounts. I'm not sure if the V6 crossmember that the motor mounts bolt to will have to be changed or not. I guess it might.
