454 transmission
Hey guys, im going to be buying a '78 Camaro this weekend which used to have a inline-6 in it (nothing now) and im pretty sure a 454 which i am planning on installing will not bolt up to the original transmission in it now.
What kind of tranny will work?

Re: 454 transmission
As far as the older stuff goes,any chevy trans will bolt to any chevy engine. Weather or not it will hold up to the 454, may be another matter. What is in it now?

Re: 454 transmission
It's probably a TH350. My ex-wife's car she had when we first got married was a '77 Camaro with an I-6 and a 3 speed standard.
Either way... they'll both bolt up to a big block. Won't last long... but will bolt up.  Gary

Re: 454 transmission
so the bell housing is big enough? just to make things crystal clear, the 454 SHOULD bolt right to the transmission without changing anything?

Re: 454 transmission
Yes... the back of a Big Block is the same size as the back of a Small Block and vice versa. How do you think the TH400's are being bolted up to Small Blocks?

Re: 454 transmission
Don't forget you'll need a 454 flexplate. 454's are externally balanced and the flex plate is balanced differently from small blocks.

Re: 454 transmission

Re: 454 transmission
The strongest transmission you can get that will hold up to the 454 with little-to-no problems would be the TH400. If you want an overdrive, then the 4L80E, but that requires a standalone computer to work with that old of a car. Very spendy.

Re: 454 transmission
TH400's were designed from the factory to handle the torque and HP that Big Blocks put out.
