I was wondering if doing performance modifications will have a negative effect on the life of my engine. I am building a hopped up 30 Coupe. I know this site is more geared towards purists but to me it is "ground zero" when it come to Model A knowledge.
Here are my plans, 5.9 head, lightened flywheel, mild cam, downdraft carb and header. My motor is rebuilt with zero miles. It still has babbit bearings and stock lifters. I plan on pulling the pan and checking the bearing clearances since I don't know who rebuilt the motor. I did do a compression check ( cold motor)
It was 58, 58, 65 & 60.
I am new to A's and don't want to mess it up. Just want some more pep. 99% of my driving is on country roads under 60 mph.
Any constructive thoughts?
Thanks, Todd
