That car came with the Olds bolt pattern ONLY. So you will have to use the
Olds 350. HOWEVER, you can get a tranny out of a Monte Carlo, or a Gran
Prix, an slide a Chevy 350 motor in there, IF you want to change the
exhaust, wire harness and if I am not mistaken, the fuel pumps are on
opposite sited of the block, so you would have to reroute the lines.
I would find a Olds 350 and be done with it.
I agree on the transmission; if you don't find a
dual-pattern bellhousing in that
car, a Chevy pattern slushbox must be procured. If I recall, however,
the fuel pump is on the same side as
a SBC, just a little relocated and harder to get at on the
probably all that will be needed is a different length of rubber hose to
connect the pump to the steel line.
There should be no problem swapping the carb and emissions equipment onto
the Chevy mill (assuming the manifold is compatible, ie., 2bbl or 4bbl,
and the same style EGR (negative or positive backpressure) valve is
it should be noted that a BOP (incl Cad) HEI distributor will *not* fit a
Chevy. If a computer control system is being retained, a Chevrolet 7-pin
HEI must be obtained (7 pins on the internal module, with a weatherpack
pigtail (in addition to the cap connector) hanging out the back of the dizzy.
The distributor will not have
a centrifugal advance mechanism.) It should also be noted that the
appropriate PROM or ECM may be needed to assure smog compliance and
driveability with the different engine. If smog compliance is not a
requisite, an older 4-pin HEI (has centrifugal advance, no weatherpack
connector) and non-ECM carb will serve. If this route is chosen, the
only electrical connections will be the starter, power to the HEI,
alternator, and oil/water/etc senders, and probably something I forgot.
Much of the torturous vacuum hose mess will be disposed of as well.
I cannot speak with certainty on the exhaust concern, but if SBC exhaust
manifolds from another B-body ('77-'90 Caprice/Impala, for example) are
sourced, the outlets should match your existing Y-pipe.
In short, selecting all components from a Caprice will ease matters: the
motor isn't as likely to be bagged out as a truck or F-body, and misc parts are
more likely to
The "little" stuff should all be verified: watch the motor mounts, the
water pumps don't interchange, the waterneck might not be oriented
favorably, the radiator hoses may have fitment issues, you may run out of
beer, etc. I prefer to think of these little surprises as convenient
reasons to spend a nice, relaxing day goofing off in the wrecking yard.
