5.3 w/ a th350 swap ?s - Third Generation F-Body Message Boards

Another LSX swap started. I picked up a 5.3 yesterday and have a fresh Th350 that i would like to make use of. i've been doing a lot of searching and cant come up with some answer.
1)Will the S&P or Trans Dapt style motor mounts work? I've already deleted A/C so the k member clearance isnt a problem.
2) will the B&M torque arm kit still work with an lsx swap. Not sure if the motor mounts will move the transmission location.

Not sure about the S&P, but if you've removed AC, the TransDapt ones will work. They should locate the bellhousing in the same place within the chassis. The problem with the plate was it ends up where the AC sits.

You will need an adapter to fit the TH350 to the Gen III engine, but I'm not the right person to provide details.

thanks for the help, I'm going to order the TransDapt mounts. As for the trans. adapter this should be all i need after i elongate the flexplate converter holes. http://store.summitracing.com/partde...HP3795&FROM=MG

I'd recommend the GM version over the Hughes - looks like it attaches a little more securely... See here: http://jeepinpete.com/engine_trans_a...ans_adapt1.htm
