SM420 or.....

Ya im seriously considering TH350 cuz i already got one and it'd be nice to put it in drive and go. Im just affraid i'll be missing my granny first gear to much.

If your gearing is good, go Auto and never look back. I was a manuel only guy, but will never go back. Auto's equipped with a stage 3 shift kit(Full manuel) are just like having a MT, but with no clutch pedal. Life becomes alot easier behind the wheel.:;

I would personally keep t-18 and rework a bellhouseing to fit the chevy Its cheaper and you also wouldnt have to mess with tranny mounts driveline changes so on and so forth . All though the auto Idea has mearet but I wouldnt go with a auto unless It was set up properly with a low stall converter and a stage 3 kit.
