ZZ4 Rebuild
I noticed that there have been a lot of ZZ4 Swaps. I am not asking about how to do the swap but more so of where on summitracing or any where to look for the correct rebuild kit.

Re: ZZ4 Rebuild
It depends on what all is in the ZZ4.
GM did switch some minor parts every now and then.
What is wrong with the motor?

Re: ZZ4 Rebuild
That's a Vortec roller block. Other than the 1 pc. rms related parts, it's pretty much your choice.

Re: ZZ4 Rebuild
And, you'll need to know if it's been bored, crank turned, etc.

Re: ZZ4 Rebuild
So this is a GM Gen-I Crate motor from 1995-2000. I am confused when you say other than the 1pc. rms related parts. Do you mean that it is the same as the ZZ4 with the exception of the rear main seal.

Re: ZZ4 Rebuild
Could be a truck block or a ZZ4/crate motor block. They're all 1 pc. rms. So, your crank, rms, flex plate/flywheel and pan gasket all have to be for a "roller" block. Beyond that, it's all a matter of choice/budget. There's people on here a lot smarter than me, so try a search.

Re: ZZ4 Rebuild
What it "used" to be has very little bearing on what it is "going" to be, especially if it needs boring and new pistons
It will take any SBC parts you wish or can afford to put in it taking into consideration as noted
it is a late model block with a 1 pce crank and OEM roller cam
ZZ4 used the 4 bolt version of your 1 pce block with a better crank ,alum heads, different pistons and a ZZ4 cam.
Block casting #10243880 350...95-00...2 or 4 bolt...
roller cam, one piece rear seal.
Vortec truck/Van Gen.I crate motors and GMPP ZZ4

Then it wasn't a ZZ4. They all had 4-bolt main caps.
That's all you really need to know to get the rebuild kit. New pistons, bearings, etc., will pretty much replace anything that was unique about the ZZ4 as far as the kit goes.
