I am running an 88 Formula in the Florida region and feel like I am finally getting to the point of being able to enjoy the car. I built this car from a street car and have run it 5 weekends over the past year and a half or so. This is my first GM (after 20+- Mopars and a couple off brands) so it is like learning all over again and it has been a school of hard knocks. I am working on engine number 4 after splitting a crank in 3 pieces (wrong flywheel), breaking 2 main caps, and destroying most of the main bearings on the first 3.
This engine has been fully balanced, blueprinted, bored and other things my machinist tells me are required on all out race engines. The amazing thing is I have not lost any rod bearings so I know oil is getting through the crank. I now have enough seat time that I am finally learning the unique handling of the car and am trying to get quicker. In spite of all my issues the car has finished all the races and enduros it has entered and always drove onto the trailer except for the obvious crank break which occurred in a practice session.
I have been reading a lot on other forums regarding springs, sway bars, and general setup and have come to the conclusion that these cars seem to have more of a personal preference setup rather than a "standard" setup.
