The crew has the original stock 4.3/700r4 and I haven't and won't mess with it. I traded a few cabinets for the dual exhaust. I have really tried to keep it in original condition due to it's rarity.My question for the CrewCab 1st Gen S10 is what is under the hood...I don't think it would be a lowly 2.8 or 2.5. I would gess a 4.3 if it was a V6, but with the exhaust, I want to say you have an 8. For no other reason then you have dual tail pipes of a decent diameter.
I have a couple other s-10's that I did the v8 conversion to but oddly enough they both have single exhaust (very quiet). However the fuel injected one (left) has a DMH electric cut out which dumps the exhaust right after the headers at the touch of the button.... :walkman:
