Im going to look at a 1996 gmc suburban thats for sale. It has a 7.4 vortec with a whipple supercharger. Anything specific i should watchout for on this vehicle? Any idea of what kinda power this should make? Im not sure about all the detailes on the motor right now (the car lot selling it knows nothing about it)...

 

id stay away from it personally. I knew a guy who had a 2500 454 with a whipple and wasn't very impressive. Gas milage probably reallys sucks to!

 

they are bad about leaking stock injectors when sitting. and fpr's

 

some have valve spring issues ( breaking) that i know of.

Drive it and tell us how it runs!
