I've run all solid mounts for 10 years--no broken trans ever. If the engine, trans, and chassis are all tied together solidly, what's going to cause the trans to break? It breaks from twisting-something is flexing where it shouldn't be. Does the car have frame connectors? Are the body mounts soft and squishy? Is the rollbar built properly? Does it tie into the subframe connectors?along with solid motor mounts and solid trans mount being run together
Broke first pass! This is what the slip shows. I shut it down, or should i say IT shut me down......No ET's? Broke first pass?
That's not going to break a case either. What do you consider incorrect pinion angle? I ran 8 degrees for many years--it doesn't do anything. Have you ever looked at the angle on some of the trucks these morons drive--4 ft. of clearance and the driveshaft pointing straight down then practically a right angle into the diff?Mine was caused by an incorrect pinion angle
x2 on what he said. Don't just assume it was more power that caused that to break. TH350 cases are fine with more power than you have. Something else caused that baby to break. Some sort of flex/bind/vibration.ya gotta really think what might have caused this. Some force was acting on this that was not inline with the rotational mass of the internals of the transmission possibly. I used to work around jet engines in the Navy and they are very sensitive to stuff like that. Vibration is a killer to them , and may have been the culprit here.
Was your engine balanced ??
I knew a big block racer back in the 70's that ran a 454 with a turbo 350 and never had a case problem. He was one of those guys that ran one track on sat and a different one on sunday all season long too
Seeing how "all over the place" this dude is, I'm surprised he doesn't have oneTime to put a lenco in there......
