4.3 LT1 external parts the same as a 5.7?
I have a 95 5.7 from a Z28 that is just a longblock, and I found a cheap 4.3 LT1 I could use for parts to finish the 5.7..is the intake, opti, tin parts, etc the same as the 5.7? I would guess the injectors are a smaller size, correct? Also would need to use the hub and flexplate, would they be the same balancing as the 5.7?

The intake opti and tin are indeed the same, the injectors are smaller at 19lbs.
The damper hubs varied by year and model and have to match the accessory bracket you plan to use, the 96-7 hubs got shorter to make roo for the CPS reluctor and the y,f,b-body all had different accesory brackets which endup at different distances from the block, wacky thing is I believe the Vette had the belt furthest from the block.
Lots of good stuff on an L99, oil pump drive specifically is another good part to snag.
I am unsure of he balance on the L99 flexplate as it compares to the LT1.

thanks for the info..so if I want to use the press on hub on the crank from the 4.3 I should stick with the 4.3 accessory drive? (if I the balance is the same and I can use it) This 4.3 is a 1996 model.
