engine build for reliability

hell a 440 could be stone cold reliable in the car.. engine size really isn't an issue especially if its closer to a stock build...

to me parts availability is a big part of it too.. when ya start getting into msd dist and things like that you may not be able to run into your corner store for the parts to fix it...

keep it simple in my opinion...

Actualy my MSD probillet distributor has run most of its miles with a GM cap and rotor,cant remember partnumber or application but you just ask for a stock cap and rotor for some old smallblock chevy with breakers from the pre HEI era and you will be good(except the sparkpluggterminals that runs HEI style terminals but not realy a problem either just replace wires aswell.)
