Q:

Do you have a flexplate for 700r to 1999 Ls1 6.0

Asked by JAMES on June 16, 2017

A:

Thanks for the question. We do not currently offer any adapters for your application. The 6.0L engine with cast iron cylinder heads should only be used with the original transmission due to a different crank shaft stick-out length. It does not have a recessed crank.

Q:

When bolting an older transmission to an ls engine I heard that the converter bolts dont line up and the hold have to burred outward a little bit. Is that still the case with this flexplate or will the converter bolts line like they should with this flex plate?

Asked by DAVID on March 17, 2017

A:

Thanks for the question. The flex plate in this kit has been specially modified to accept the torque converters from a TH350, TH200R4,TH700R4 and Th400 with no additional modifications.

Q:

Will this work with a 94 4l60e on a LQ4 engine?

Asked by STEPHAN on July 04, 2017

A:

Thanks for the question. This adapter will allow you to bolt a 4L60E from a Gen I or II engine to a LS based engine. This kit will not work on the early LS 6.0L engines with cast iron heads. You should retain the original transmission on these applications.

LS SWAP to TH350 JEEP CJ7

ADD-712500A
Worked perfect with the GM LS3 525HP CRATE MOTOR from SUMMIT !!! Starter and Ring gear aligned right up as well as the flywheel/flex plate to CONVERTOR TAB HOLES. Only pulled the CONVERTOR 3/16" to mate them. You must use this item with all the old vintage trans. Original trans fill tube will need to be modified or something that fits, cause the engine block/heads sets back further than a SB CHEVY. ...read more

Installed this on a 2004 LS2 6.0L with a corvette 700r4 transmission. Had a gap of about 3/16” between the torque converter and flex plate. Worked perfect. Thanks again Summit & Advanced Adapters.
