"grumpy ?will upgrading from a 350 to a a 383 kill my trans?
I'm a bit concerned that the extra power might fry my transmission?
the abuse or lack of abuse your engine will be transmitting to the transmission and drive train has FAR more to do with your driving style than any increased engine displacement, or put a different way, a 350 driven like you just stole it is far more likely to cause problems than a 383 you drive like a normal daily transportation vehicle.
the 383 will allow you to reach about the same power levels at about 400rpm-700rpm lower in the rpm band, heat and torque and sudden shock loads kill transmissions, having an extra 40 ft lbs of torque available is usually not nearly as detrimental to transmission durability as running the car hard or doing silly stuff like tromping on the throttle while sitting on wet pavement or gravel where by doing so your submitting the trans too both rapid heat increases and sudden shock loads, or by using slicks which significantly increase traction.
I know one kid that destroyed two transmissions by revving the engine in neutral and dropping the transmission in drive at higher rpms , if you abuse a transmission like that even a 283 can quickly screw up a transmission
having a trans cooler and traction bars also helps reduce transmission failures, as both heat and wheel hop are reduced
