F bodies got the 2 bolt blocks, all Corvettes got the 4 bolt version. Most of the factory replacement blocks were 4 bolt mains. Also, all LT4 blocks had 4 bolt main caps.

Also, I think you're going to be over taxing the 42# injectors with that setup. Mine are pretty much maxed on my car already (heads, cam, 8 PSI S trim, Alky). Just thought you might want to run the math before you buy a set. I'm guessing you're running a P600b or a P1SC on the car? :-)

Yes I am running the P1SC. The 42#'s should get me where I need to be, the 30#'s I had in there held up very well the dyno run I did last summer at 6psi was a little short but mostly due to the fuel pump. I already had the 42#'s here so I'll put them in, and I am jumping up to 12psi. Then edit the PCM and do some tunning. If they don't work then I'll buy some bigger injectors. Also thanks for the input on the blocks. Thats what this clubs all about ... helping one another when ya can. :smt077

Just thought that I would add that all 96 Vettes that were not automatic were LT4s. From what I remember the Grandsport was an even nastier version (actual hot cam) but not sure. All the LT4 Camaros were aniversary SS cars (actualy anivesary cars as in the white with orange stripes) and I think there were about 100 of them and I think a couple dozen Firehawks were made with them.
