1972 nova 350 engine

HI
I have a guy selling a t5 trans for $900.00 is that a good price? I saw one on ebay for $350.will it go in a 1972 Nova with 350 engine and 4 speed muncie m21 I want to replace it with a 5 or 6 speed but don't want to break the bank or do to much cutting of the car is this the best trans for my nova?
i guess that the trans mount is not located in the same place, I was also thinking of puting a 454 in my nova will it fit with my 350 motor mounts?
Thanks

Hi,
The T5 is a week transmission, it would probably be okay w/the 350, but I think the BB is to much, price $350. $450. why do you want to change to the 5 speed?

Get BB mounts, then test fit the engine, get it where it needs to be & mark the location, then either drill new holes or weld the bottom of the mounts in.

You might want to install frame connectors w/t BB
There are BB front coil springs? you may need a larger radiator as well + exhaust, fuel system, what about the 10 bolt? just some things to think about.

I buy good T5's for around 500.00.

great transmissions but a little weak. shift them slow and avoid clutch drops and they will hold a lot of power. avoid drag slicks.

what??

13.5 et at 134 mph?

134 mph trap speed means your engine is making over 650hp and should be running high 9's or low 10's in the 1/4 mile.

105 mph would be more suitable for a 13.5 et.

if the engine is revving at 4000 rpm at 60 mph then it should be revving 9,000 rpm at 134 mph.

the car would need to have a 5.54 gear to rev at 4000 rpm at 60 mph with a 28 inch tire. Are you sure the tach and speedo are right?

a 3.73 gear, 27 inch tall tire, and 4 speed should rev at 2800 rpms at 60 mph.

A T5 works nicely for a 12 second car. just don't beat it up. shift a little on the slow side and it will live a long life.

YOW! Or even 95 MPH for a 13-fifty.

But if you were hitting 134 MPH, you'd be all like, "This thing is awesome!"

And the tech guys would be telling you to PARK IT until you got a cage, etc.
