I have an LT-4 manifold for sale on e-bay. It has been bored out to accept a 58 mm throttle body. Any questions contact me here. The link is: LT-1/ LT-4 MANIFOLD FOR '92-'97 CORVETTE/CAMARO LT-4 . There are pictures of it also.
Just go to E-bay motors and type in "lt-1". And then look for LT-1/LT-4 MANIFOLD FOR '92-'97 CORVETTE/CAMARO LT-4.

Thanks

 

whats the price?
