no
Not even close...
No. The Pontiac headers will not bolt up to the Chevy small block.
Yes.
Before 2000, yes. After, no.
Weak battery, starter solenoid, or starter.
Pontiac uses same block no small or big, Chevy describes their engines small or big
No, no, no. Two totally different motors.
Shimming any GM starter is likely going to assist in better performance of the starter. It cuts down on heat radiation and vibration when not in contact with the block.
Depends on what size small block or bb chevy. Cast iron or aluminum. All of these must be taken into consideration.
On a small block Chevy the distributor goes through a hole in the intake manifold. On a Pontiac the distributor goes behind the intake manifold.
Some do, some don't. The distributor, starter and alternator fit, the water pump does not. The mounting brackets are all different.
If they are indeed both small block Chevies, then yes the intake will work.
