I suspect I've fallen into every engine-swap trap in the history of
GM. In addition to the brackets and motor mounts issues mentioned
previously here's the ones I remember slapping my forehead over:
Check that throttle linkage is compatible, that the kick-down rod or
cable still fits, that the transmission coolant lines will clear the
new block, that the positive battery cable will reach the starter and
stay off your exhaust manifold and pipe (fire sucks), that the wiring
(warning lights, gauges, distributor etc) will reach and connect, that
the power steering pump will clear the frame (or will match to the
other block if you choose to leave your Chevelle's in place), that you
have radiator and heater hoses that fit, that your exhaust manifolds
will bolt up to the exhaust pipes and, if you keep your Olds
alternator, that it's the same type (internal or external regulator) as
the one on the Chevelle block. Maybe for a '70 that won't be an issue.
Also, if you change intake manifolds and/or valve covers, make sure one
or the other still has an oil filler hole - that was my all-time
favourite gaffe.
I've made all these errors, and more I can't remember. And, when you
slap your forehead and say "Doh!" make sure you haven't got a 9/16s
wrench in your hand (ouch!).
BTW, can the list help me with this one: I've just put a 283 with an
HEI distributor in my '66 Chevelle. But the wiring harness off the
firewall was for the old points-style distributor and coil. Do I hook
up to the BATT terminal on the HEI those two wires that formerly went
to the coil? Or just one, and which one?
Thanks for any assistance.
Del, with a dent in his forehead :-)
