The basic 472 and the later 500 engines both use a standardized Buick/Pontiac/Olds/Cadillac bell housing pattern, so a Turbo 400 automatic will bolt right up to the back of the block as long as the proper Cadillac flexplate and torque converter are used. The Turbo 425 front-drive automatic transaxle also fits these engines as used in the Eldorado, although a special dual-sump oil pan and pickup are used with these transmissions due to the required half shaft clearance. Any rear-wheel drive engine can be converted to front-drive and vice versa if the proper oil pan and pickup are used, although 2 of the main cap bolts must be removed and swapped to mount the pickup's bracket. Another good thing about these engines using a Turbo 400 transmission is that a B/P/O/C patterned case can be stuffed with the Chevy 4x4 tailshaft and associated hardware for use in an off-road truck. The engine weight is approximately 600 pounds fully dressed and splits the difference between small and big block Chevy, so suspension modifications are not usually necessary. Transfer case choice for a 4x4 should be a 205, as fitted to some mid/late '70's Chevy 1 ton trucks. The 205 is a strong gear-driven transfer case and holds up nicely to the big Caddy's torque output. | The basic 472 and the later 500 engines both use a standardized Buick/Pontiac/Olds/Cadillac bell housing pattern, so a Turbo 400 automatic will bolt right up to the back of the block as long as the proper Cadillac flexplate and torque converter are used.

It's fairly easy to build a 2000 hp twin turbo Cad with 35 pounds of boost at 7 to 1 compression on alcohol. They say the block can take it, but the cast crank might not be able to. |

With a 2000 dollar CPU controller, it's not for poor guys. |
