Still being a little baffled, as well as quite a bit poor, I went to a
few sites regarding engines. I found out that the engine code for a
(example) 3800 Camaro engine is the same as the 3800 Regal engine -
VIN code K, and both use the L36 variant of the Buick V6.
So, with the exception of 451ctds (thanks for the encouragement, man),
no one has answered me why I _cannot_
replace a 305 on a 1987 Regal
with a 3800. Is it a question of a subframe, or a new cradle that is
used in a Camaro (or the FWD car line up)?
