my question deals with the 4.3 L v8 that came in some 90's civillian caprices. RPO L99. From what i understand, they are Gen II smallblocks based on the LT1 with a 3" stroke, 3.74" bore, 5.94" rods, and 305 pistons. 9.9:1 Compression.
I want to know what parts are interchangeable with LT1 parts (or aftermarket LT1 parts), Heads, cam, intake, and crankshaft.
I found an intake for the lt1, my main concern is that it won't bolt up, ports wont match up, etc.. also, the intake is for a carb, so im not concerned about fuel injection and smooth idle im just looking for power.
I was told that the heads are not interchangeable because of combustion chambers, if this is true, what can be done to correct this??
Also what can be done to raise the compression of these engines?
