Slip and slide transmission

The engine swap was this winters project. If I can make it last till next winter I'll be happy. Chances are it won't be more than a couple hundred miles. As soon as I drive it a few times I tend to start the next project and put it back out of commission.

Speaking of upgrades, what's a good recipe for (an optimistic) 400 horsepower? Standard rebuild and shift kit, or upgrade to Red Eagle clutches? Any hard parts need an upgrade?
Thats not many miles, you'd probably be fine but no guarantees, just like RRR said.
What year is your trans? I would get a red alto deluxe kit from transparts warehouse for the correct year. Grab the solid red band and double wrap band from A&A, A&A sells misc bushings you may need too. Then a reverse wound clutch pack spring from ati. Finish it with a transgo stage 2 and she'll be great. maybe add a billet strut rod and a sonnax rear servo.
