Hey all, new to the forum and new to the Nova, just need some input if anyone can help. '74 350, 30 over, big cam, 373 gearing and I believe the original 350 trans. I was told when I bought the car the gears were swapped from a 4.10 to a 3.73 ratio so it will ride easy at highway speeds, because of the engine work. Finally got the car on the road, has trouble going in to gear at times but shifts fine, but the RPMs seem wound pretty tight just at 50 mph. Could this be a mechanical issue or is the trans/gearing ratio just all wrong? Thanks for any help!
