Hello, I am orig owner have a 1998 S10 4x4 with the W engine and calif emmissions.

69K miles and the #6 crank bearing just went.

I have always used synthetic for 5k miles on.

I have Accel coil, plugs and wires, magnaflow exhaust (back only)

Hypertech upgrade run only Premium. 17.2 mph ave year around

Drilled and sloted roters. Tons of new OEM relavement pats over the past years. Chasing down the chuggle or shake after accelerating from toll booth.

Will be putting in new stock crank, Magnaflow cat (direct fit for Cali) Accell wires, plugs coil and distibutor.

I Need suggestion on what works best for one street upgrade above OEM for cam, lifters valve springs and timing chain.

Thats about all I can afford right now.

Anyone know of a kit? a shop or online that sells and knows Blazer S10 performance parts.

I have searched some but have been out of the game for a while, I am disabled. I put about 5K miles a year on S10.

Looking for a no problem street driving engine that will not screw up my emmissions. I live in NH and they test OBD II emission each year as a requirement to get an inspection sticker.

Thanks for youe help in advance
