Appreciate the advice and tips 66vairguy. I don’t want to be penny wise and pound foolish as you said. Was just exploring the option since this will not be a performance build- but don’t want detonation or possible dropped seat for the $5 difference per fill up!66vairguy wrote:An automatic (PG) Corvair needs an engine that develops most of it's power at less than 4,000 RPM. The 110HP engine is a good fit because it develops more power at lower RPM due to:
Longer stroke vs. EM engines
High compression
Smaller valves vs. the 140HP engine (four carbs)
In fact when the 140HP engines was ordered with a PG it was really more like 120HP since the PG version came with a 95HP camshaft that was retarded by a special crank gear to try and flatten the torque curve over a broader RPM range. This was done because the 140HP engine from the manual transmission car just did not work well with a PG.
By today's standards the 110HP PG Corvair is just adequate in modern traffic, but it does the job well. In heavy city traffic it is actually a lot nicer to drive than a manual transmission Corvair.
Just my opinion based on subjective experience.
I offered to get him a newer car but he wants nothing to do with them. Probably my fault since I’ve been daily driving classics since before he was born. My oldest son got a ‘63 Spyder for his 1st car and I don’t think that helped either. But he wants the cruiser style of the PG.
Looking fwd to doing this build with him. We’ll upgrade to front discs if possible since I haven’t found any info on a dual master conversion for the ‘60. Also putting seatbelts in her for him and passengers.
