Questions & Answers Ask a Product Question

Would this work with the stock 12.75 inch flex plate on a 350 sbc crate motor?

Asked by GARRETT on February 22, 2018


I recommend installing a new flexplate on your engine...standard plate...168 teeth.

Answer This Question


I have a 1985 gmc half ton truck with a 350 motor with a edelbrock 650 avs2 carburetor edelbrock performer rpm intake and an edelbrock performer cam and lifter kit. my transmission is a th350 non lock up with a b&m shift kit on the street and strip setting and I'm wandering if this stall coverter will give me a better launch of the line.

Asked by SCOTT on March 04, 2018


Yes it will. I the same set up on my 327 with this same converter and it gets off real quick
Maybe one we’ll meet sidebyside and test them both out
It’s worth the buy.

Does this work with a comp thumper cam?

Asked by MATTHEW on August 19, 2017


Pending cam duration @ .050, this converter will work for a mild street build. Be sure to run a good trans cooler as a looser converter will create more trans oil heat.
