Yeah, Jeg's has the BOPC to Chevy adapter plate for 60 bucks. I'm going to stick with stock flow for the TBI at this point as the Caddy is going to be putting out so much grunt that any extra flow is going to be wasted. I'm going to use a cam improvement with roller valve train, headers with a free flowing dual exhaust with oxygen sensors for the TBI computer.
The next big purchase right now is a good used 4L80E to go behind the Cadillac. I want to install the engine and trans as one unit to do it in one shot.
