First post, been doing a lot of reading.

I currently have a stock 1989 3800 with auto trans that I have put into a trike. The drive line has about 80k on it.

I also have a SC from a 92 or 93 Buick Park Ave complete with crank pulley and intake.

Questions: What gaskets will I need to install the SC? Intake, valve covers?
Will the ECM need to be changed out or just re-programmed?

I'm sure I'll have more as I go.

Thanks.

I don't think it will bolt on that simply. Also, without changing a lot in a naturally aspirated 3800, it will thrash itself to death with forced induction added.
