CarCraft of Riverside has shelves full.
Change classes, not rules.
A lot of drivers have learned how to drive with these rules and so can everyone else. Putting expensive parts changes the class. Expensive parts will allow guys to drive how ever they want when ever they want with no consequences.
Stop trying to make change to the class and make change to the driving habit with the current parts and rules. This is a drivers/prep class and it needs to stay that way. Use the money on better prep or another class.
I dont understand how you are going to be pushing the car harder with a 388. Its the same final drive as a 412. Its just stronger so it last longer.I'm ok allowing aftermarket parts but , not open the trans. If we open the trans will push the cars harder and what will be next. Get rid of drums,stock arms ,spindles ?
