Ok guys I posted on here a while ago asking about 6 cylinder perfomance. Since than I have decided to go with a 350ci engine swap occuring this winter. I have some tecnical issues to work out in the mean time.

The current engine is a 250 I6 with a Powerglide attached to it. I have a Turbo 400 in good shape also in my garage. If I keep the powerglide and attach it to the 350, will it be able to take this abuse?

I mean, switching to a Turbo 400 would cost me a lot more money.....new driveshaft, cableing, mounts, speedo gear...etc. As well as a sh*tload of work in my opinon.

So I would rather simply unbolt the 250 I6 from the tranny and take it out and drop in the 350 and bolt it up to the old powerglide.

So I need to know:

Can I use the powerglide and how can I make it take more abuse.

The engine I am building (1970's Chevy 350ci) will have about 400hp and 420 ftlbs trq. at the flywheel, can my powerglide take this?

Cheers Thanks a lot.........Steve
