a TF truck is easy to convert to a v-8. 55-59 cars and trucks used front
mounts on the motor and side mounts an the bell housing (the trans just
hangs there) vs a newer chevy would have side mounts on the motor and a rear
buy a v-8 bellhousing for a 55-59 car or truck and the motor mounts that LMC
sell and it bolts right in with your trans. the bell housing must have the
side mounts on it (other years may fit, those are the years i know fit). it
even uses the 6 cyl trans mounts. you will loose the floor starter as v-8s
all had solinoid starters.
the motor mounts bolt to the front of the engine. if you have a period motor
you will have the holes in the block. if not you will need to drill and tap
the holes. all sbc motors have the machined surface where the motor mounts
go (even a new GM crate motor with 1 piece rear seal), some have the holes
for the mounts, as chevy bolted accesories on the motor using the same bolt
pattern. if you have to drill new holes, the top right hole will go into the
same space that the gas pump rod runs thru. just meke sure the bolt is
correct length to not pin the rod. your 6 cyl front crossmember has the
holes for the v-8 motor mounts punched in it. the LMC mounts fit, but if
your after the period correct look, find a set out of an original v-8 55-59
truck and bolt them in (factory mounts were riveted).
you will need all new accessory brackets (stock is generator only), center
drop exhaust manifold (aka rams horn) (to clear the steering gear) with the
generator mount on it and a new exhaust sytem. wiring is the same. short or
long water pump will fit but the generator mount is for a short pump, the
fan needs a spacer to get close to the radiator. if you have a fan shroud it
will still work.
if you want to change to a newer trans to get overdrive or an automatic,
then you need side motor mounts and a trans crossmember and mount. that
would actualy be easier to find parts for.
i'm sure i left some out and other will chip in. write if you need more
