The front cover is very similar if not the same they made them out
of Al. & Mg. The Buick GTP motors were made from 1984 to 87. The
indy lights chassis was produced by March Engineering in 1986 20each
1987 to 89 10 more .You are right the engine was detuned to a even
450H.P. all by Ohio George and were bullitt proof. The Gtp car were
capable of 3 to 4 G's in fast corners so the Cosworth pumps were needed
The Cosworth pumps have 1 large pressure pump 100 psi 2 or 3 scavenge
pumps ( 3 for turbos) and 2 water pumps. The water pumps push water
thru the freeze plug holes and the coolant comes out holes in the front
drilled in the front of the heads. In the 1980's Buick was aggessive in not
only drag racing but Imsa gtp ,gtp-lights,gto trans -am, am-challenge,
and Busch GN.
hope this helps
