Hey gang,

Has anyone tried installing a supercharger from a 3800 on a 3300?

I've seen a few pics of the the factory 3800SC engine in a '95 Riviera.
Lots of stuff sure looks similar.

The intake manifold on one of my '90 Ciera's w/3300 is leaking oil a little from an end seal. If I'm gonna remove the intake,I'd rather upgrade.

the heads and intake manifold are too different to be interchanged.

If you are going to do anything do a Complete powertrain swap

Sounds like that idea is down the toilet. Thanks for the info.

I see there is a thread here mentioning that the 3300 has lower deck height than a 3800. So,the manifold cannot be a direct swap.

Thanks again,

yeh man, sorry to say that our engine is limited in what u can do to it :/ its a great-reliable block tho and if u are reeeaally interested slapp a turbo or two on the thing x) Its possible, but requires alot of mods... and is costly.

I wuld suggest saving up just go for it and drop a supercharged l67 in there,, thats what a few here have done and is what i plan to do eventually.. I might go pik up another ciera to stik my 3.3 into tho, since it is sortof built up {hate to get rid of it} good luk tho man!!! god speed! =D
