C4 or C6

I recently picked up a 429 big block to put into my 93LX, I'll be getting a stroker kit for it and some aluminum heads. What would be the best trans to use for this set-up, a c4 or c6? Also what would be a good stall converter too.

Neither........I'd get a powerglide..........

This will be a 100% street car because we don't have a track on island.

C4 would be easier to package and would probably be fine for a street style car. Glide if your gonna lean on it a lot.

Thanks! Can I get any C4 or do I have to get a specific year(s)?

Any 70 and up 26 spline in put shaft c-4 is what you need plus a reputable builder with good parts and not off the shelf assembly line junk,so called performance built transmission. Good luck

Thanks! I will start looking for one!

I agree with Dave, the C6 will be less maintenance and can certainly take the torque with no issues.

Thanks for all the feedback, I will start looking for a c6!!

Same deal with the c-6 as the c4 get someone if they do make a mistake or you have a problem with it that will take care off you.

Best core for a C-4 is a C-5. Just need a C-4 VB and bell. A C-6 of course can handle what you want with very little modification over a stock rebuild. C-4 will require more effort and won't last as long, but is lighter and easier to package.

No track? That's a sin.

Tell me about it! They close the track a few years ago on Oahu but the outer islands still got their track still open.

Have you thought about looking at a TH400 for a trans?

only way id run a gm trans is if it only had 2 speeds, imo if your gonna do a 3 gear the c6 is the ticket.

I wanted to keep all ford plus I found a donor trans on another island.
