I've searched and searched but haven't been able to find a 96-98 RCSB w/5spd & the 5.7 so I've decided to change my 98 autospastic over to a 5spd. I pulled the tranny (MG5), pedals, etc.. from a 97 w/4.3. My question is, how well will the MG5 hold up behind the 5.7. I know the 5.7 trucks w/5spd's had a M50 and could handle the extra torque of the 5.7. My truck is pretty much stock except for a new tune for the 5spd. Any advise would be greatly appreciated.

Thanks,

Just take it easy in first gear, that's where the most torque multiplication takes place. Don't dump the clutch or get too crazy in low-traction conditions. Once you're into second it will be fine. The 4.3 clutch is going to be a little weak for the 5.7L. You can always swap that later if you want to get this going quickly now.

 

Cool, thanks for the info. I plan on getting a new flywheel, clutch and pressure plate. I believe the 4.3 flywheel is a little different weight? At least its a different part number...

So, the only difference between the MG5 and M50 is the ratios (1st & 2nd)? Or is it something else?
