Its been a few years since I've been here. I sold my truck a while back to buy a new 2014 Chevy Caprice with the 6.0L and found I could not live without a truck. Luckily the guy I sold it to didn't need it anymore so I was able to buy my same truck back and thanks to my wife, still keep the LS powered 2014 Caprice! Its a 1991 C1500 with the LO3 engine and 5LM60 manual trans.
Question is, I have acquired a 1993 Caprice police version LO5 engine with 134,000 miles and want to swap it into my truck to replace the weak LO3 engine. I know the intake manifold is a little different, the exhaust manifolds need to be swapped over along with the accessory brackets. So are there any other differences these engines have being destined to go in an automatic vs manual equipped vehicle such as different crankshaft hubs or the like. IE will my clutch, input shaft, pilot bearing etc work on an LO5 that originally was mated to a 4L60? Also, I have seen that for unknown reasons, the LO5 in a police car seems to be unique in that they have a different part number and flow rating for the fuel injectors compared to other LO5 applications. I'm not sure why this is but if I have to run the Caprice Computer will there be issues with my truck not having an automatic trans?
FYI - unlike the trucks, 1993 Caprice did not use a computer controlled trans. Only has electric speedo sensor and lock up torque converter. 1994 with the LT1 was the first year of the 4L60E in the CAPRICE.
The 1993 Caprice police LO5 was one of the more powerful TBI engines with a rating of 205 or 210 HP depending on the source but everything I have seen says this is not a result of the higher flow injectors but improvements made to the vehicle's crossoverpipe and cataletic converter.
Last question, as another option, could I reuse my OEM LO3 computer and replace the PROM with that from a LO5 or do I need the entire LO5 ECM?
Thanks.
