need some help ordering parts for a 72 BB - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So.Cal.Super · 03-24-2009, 09:26 AM

I am trying to order lifters and a new harmonic balancer for my truck. When I select what I have - 72, 6.6L/402, C20 pickup
I get 1 choice, If I change it to suburban I get 31 choices.

What gives?
I have seen this happen before and the guy at the parts counter asks me if the engine was swapped. Why is this combo so hard to find in parts books?

Thanks for taking a min to help.

I think the lifters are the same from all big blocks to all smallblocks (As long as you get the right kind: Solid, Hydraulic not sure about roller, you problably have hydraulic lifters) and the balancer should be the same until you get to a 454 or larger big block -- somebody correct me if i'm wrong

If you can't find what your looking for try doing an engine search at summitracing

The harmonic balancer for a Big Block 396, 402, and 427 are all the same in all applications, whether a truck, car, or suburban. Only the 454 is different as it is externally balanced. All Chevy V-8s use the same lifters, whether solid or hydraulic.
