Just did the conversion last year
does the bellhousing have mounts for the rear crossmember, cause if the
mount is on the rear of the transmission, that is to far of a stretch for
the drive train. your straight six transmission linkage will work, If the
283 previously had side mounts the front bosses will have to be tapped, not
a big issue. basically is if the motor used front mount the transmission was
mounted at the bellhousing, if the motor was side mounted. good chance the
transmission was rear mounted. i used a bellhousing out of a 64 canadian gmc
(w/ 283) but the donor for the trany was a 69 chev w/ a straight six which
also had the bellhousing mounts. then i still ran into problems w/ the rear
hole of the bellhousing. the 4 hole to bolt the trany still line up.

okay guys, the engine is coming out of a 66 1/2 ton. I'm getting it
complete
from air cleaner to oil pan, starter, manifolds etc. It has the holes is
the
front for the front type mount, but my 6 bolts to the sides of the block.
With the V8 being shorter, I have to assume the existing mounts can't work.
I
do plan on using stock type mounts in the existing holes rather than an
aftermarket crossmember. I can get the bellhousing out of the 66, but I
don't
know whether it has the mounts to work in my '57. Unfortuantely, I am
unable
to drag the whole truck home to have them side by side until it's done. Any
more thoughts or suggestions?
