Questions & Answers Ask a Product Question
Q:

Does this product require a torrington bearing on the timing chain? Is a wear plate required? What is required to install a retrofit roller cam other than what comes in this kit. I am lost on what i need to prevent wear and cam walk. Thanks

Asked by PAYTON on February 01, 2019

A:

Thank you for your question. COMP Cams K12-432-8camshaft and lifter kit will not require the use of a Torrington bearing with the included timing chain and gear. COMP Cams 200 is the thrust button and COMP Cams is 201 is the wear plate for use with this camshaft kit.

Answer This Question

Q:

Will this kit fit in my sbc 383 stroker engine? If not what kit would you recommend?

Asked by DAVID on March 26, 2018

A:

There's a lot to that question. With strokers you may have to consider a small base circle cam. The simple answer is yes, it's intended for a small block Chevy. The lift has to be taken into consideration to make sure you don't slam a valve into a piston. Always consult a reputable machine shop if you have questions for a specific application.

Answer This Question

Q:

Would this cam work with summits SUM-150100-30 roller block?

Asked by MATTHEW on January 23, 2018

A:

Thank you for your question. The Summit Racing 150100-30 engine block accepts a factory roller cam and lifter kit. The COMP Cams K12-432-8 retro-fit camshaft kit fits a non-roller block. However, we do offer a COMP Cams part number K08-432-8 which is the same grind on a factory roller camshaft.
