I'm getting a low mileage turbo 400 out of an '89 3/4 Suburban that's being parted out. I did some searching and it looks like I also need to get some switches off the throttle linkage/pedal assembly. I'll pull the entire assembly just to be safe, but is there any thing else I should grab while I'm at it? I'd like to bolt it up to the 241 that's already in my '90 Jimmy. What modifications will be required to do this? Is it as simple as installing a 32 spline input shaft into the 241?
