I have a Ram musclecar series 11" on mine and I think i hurt it for the first time a while back running the truck hard..... I launched hard revved the 383 to 6000 and slammed it into second and let go of the clutch and the RPMs shot up... I thought I had missed a gear, but it was in gear when I checked.
the ram musclecar series is almost $100 cheaper than the centerforce dual friction.... and your 350 probably would not hurt it. But if you have the money and you wanna be absolutely sure... do the centerforce.
here is the clutch i used... I don't know if yours would be the same though because I have a late-model (89) SM465 with an aftermarket flywheel.
