Thinking of putting a 3.8 SC in my 99 s10

If it was an older s10 with the 2.8 I don't think there'd be much problem since the 2.8 and 3.8 have identical motor mount positions...

Mike he said it's a 99

I know :(

so now its off to u-pull for the motor mounts and what ealce i can find/ I need/want
I found a guy that can do some special /custom work on the intake I’ve been looking for the pic he sent me of how he fit a 3.8 SC in a dodge Shelby

I have put 3800s into just about everything...

Put a 3800 turbo setup into a full sized tahoe before... thing worked awesome, built for towing his 6000lb trailer behind his 5000lb truck, and he gets 14mpg pulling and 18mpg not pulling.

so what type of trans did you put behind it?
