I'm collecting my parts for my boosted engine
370CI with LSA heads and LS3 intake manifold in my 2004 C5Z06
the problem is my stock throttle body is 3 bolt while the LS3 Intake is 4 bolt so i have to change the throttle to 4 bolt throttle
Any idea if LS7 throttle body will work if i used the Caspers electronics adapter ?

You need an LS2 TB and the appropriate electronic harness

That throttle body harness is for an LS-2 early LS-7 silver blade TB.
These TB`s have become quite expensive. The later LS-3 / LS-7 TB`s ,
gold blade are much cheaper , but may be harder to tune, as the blade rotates the opposite way. Both are 90mm.
