Just looking for a little info here............
have an 80 Z28 with a 350 and have sitting around a newly rebuilt 396 which
is getting lonely.
any problems you guys can think of that i may run in to?
also, what changes will i need to make.... engine mounts, engine mount
location on crossmember, tranny, driveshaft.
any help is greatly appreciated.
if you know of any sites with helpful info on this swap, that would also be
I've done a few in my time, depending on which transmission is in the car,
and which replacement you will put in, is what will determine driveshaft
In 1973 they started using the motor mounts with the cage on the block, but
will still fit up.
The only problen that I can possibly forsee is: The motor mount pirches on
the frame, came in three different setbacks till a certain year: Small
block, big block and big block with A/C.
Whick only affected the old blade type throttle linkage, if the motor was
set back too far. If you have a cable throttle. I see no problem, except as
I mentioned with transmission changes.
Remember to replace the coil springs, otherwise the negative camber will
wipe out the inside of the tires fast!
The 400 and 350 have different size universals,
Lakewood makes one to adapt it, but a good drive line shop can give you one
in Neapco, I don't remember the number but it's $40.00 cheaper.
The TH 400 uses a bigger yoke, I forget the spline count, and the drive
shaft will be a different length.
