Hi! Nice to be on a site with so many other Nova lovers. I have a question, I just recently purchased a 1966 Nova. The car would be what they are calling a pro street car. The guy I bought it from just drag raced it, he did not drive it on the street with the fuel setup that he had on the car.....he was running a rons flying toilet burning str8 ethanol. Anyway, back to my question...he has been racing this car with a 388 sbc producing 600 horse, running 11.00's at 5000 feet of elevation. The car still has the stock rear end....8.2 ten bolt with stock axles! The car does have a ladder bar setup on it and there is a spool in the rear end. He was running a transbrake launching at 3200 RPMs with no problems....he said that he has broken the spool twice.....when he got greedy and tried to launch at a higher rpm. I also plan on drag racing this car and don't want to have to replace the spool every other month. Is there an alternative to buying a complete 12 bolt Moser or Strange rear end set up???? I read an article on chevy high performance about a rear end swap using the 8.5 rear ends out of the 73-79 Nova's, but they are too wide for the first gen cars. Any help would be appreciated. Sorry that was so long winded!
