The "car" has some nice stuff in it. Trans, clutch, suspension, etc.
But the motor in the car at the Dutch is the spare motor, and there is no modern high tech stuff in that one.
When he first started racing in Stock, after a few years of bracket racing, we put a stocker motor together and stuck it in the car(the gto). It was an auto back then.
It wouldn't even run the index at first.
We got to be a little friendly with some of the other guys running Stock and picked their brains for what we were missing.
One guy, who was racing a 68 396 Camaro running well under the index told us, "ya know...... When I freshen my motor, I look at the stuff inside and think to myself, 'I don't know why this thing runs this good".
We thought that guy was just lying out if his a$$.
Then....... Once we got the car to come around and running better we realized he was telling the truth. Once you figure out the combo...... It's not that hard.
A guy who has been around class racing quite a while, and has done several pretty good running combos told me, "cam, carb, converter". In our case that's "cam, carb, clutch".
Proper basic machining practices along with a decent car and "the 3 c's", and it will run pretty dang good....... Without any tricks.
