Manual Trans Help

mtwilly · 02-24-2010, 05:46 PM

Hey, guys. My project is a 1976 Firebird with a 400. I am building it for NHRA Stock and i want to run a 4 speed. At this time, a Jericho is out of the question so what is my best bet? Super T10? Thanks for the help.

Spend the extra for a Jerico, it will pay for itself in the end

if your going to run a stick you need to go with a good trans ,jerico,liberty,but depends how resourceful you are you mite be able to find a doug nash five speed that is converted to a four speed but finding gear ratios will be a challenge to find ,,strong but old

You car is only as strong as the weakest link. The T10 would be the weakest link.

Your problem won't be so much the trans , but rather ,the clutch.
Too much weight, not enough hp and rpm to use counterweights effectively.
I f you can't afford a Jericho, I'm going to assume you won't be able to put a good clutch in it either.
You CAN find an old Doug Nash 4+1 with about a 2.96 low and it will be strong enough, but remember, a 1 to1 4th gear, is still driving through the cluster. You 'll have some loss there.
Bottom line though, is, and trust me when I tell you this (been there, done that) , this whole deal is a bad idea. I would advise you to not do this.

What whole deal is a bad idea? Running a stick or building a stocker?

I'm new to all this stuff, but isn't all that stuff adjustable in the clutch?
