Tearing down & rebuilding the top end on my 1999 Chevy S10 ZR2 4.3 liter V6. Tore down to the block & rebuilt with ARP studs, mercruiser / mercury marine intake, complete with proper fuel injectors & rails. So much better to be gone with the awful fuel spider!

A NOTE ON EMISSIONS: No worries so long as you run a wideband o2 sensor (a must for proper EFI tuning anyway) to dial in your air/fuel ratio by making changes to the newly installed fuel pressure regulator needed for the swap. The emissions testing will check your OBD access port for error codes, no problem if you've wired up the new injectors correctly (see link in the description). They also insert a "sniffer" in the tailpipe to verify the exhaust gases & particulates are within the limits defined in your region (O2, CO2, CO, HC, etc). But that'll be a non-issue if you're running a catalytic converter & have you're air/fuel ratio set.
