Questions & Answers Ask a Product Question

My crankshaft has never been tapped for a damper bolt. Can this be used only pressure fitted on as some earlier engines were? Or is it recommended to tap and bolt on?

Asked by ZACHARY on November 19, 2017


I tapped my old 283 out just to be sure. I think if it came off a new radiator would be expensive when the damper went through it!

I have a sbc 350 motor with the casting number 3970014. Would this balancer be the appropriate diameter? If not which would be best?

Asked by JOSHUA on March 13, 2019


Thank you for your question. The Summit 161350 harmonic balancer is designed for internally balanced small block Chevy engines. You can verify fitment using the Applications tab on our website. The diameter of the balancer is relative only to the timing pointer.

Will this work with the blueprint 355 crate engine I just purchased ?

Asked by MICHAEL on April 16, 2018


Thank you for your question. The Blueprint BP35512CTC1 375 hp dressed crate engine is compatible with Summit 161350 balancer. However, you may want to consider Summit 161358, as Blueprint recommends an 8 in. balancer with this engine.
