Guys,

New to the site!!!! Need some help to identify a 4.3 V6. I bought the motor a few years back with the intent of upgrading my 93 C1500 to a Vortec 4.3. My old truck has 216000 and the original TBI V6 still runs like a top. My plans where to swap the motors out. The problem is with fuel system. It appears to be a CSFI (Central Sequential Fuel Injection) motor. The motor is a complete assembly line unit down to the plugs (new never fired). The interesting thing to me is it is stamped with the following GM 4.3 LG. Does anyone know what this motor wasfor....I thought it was a 1996 blazer motor now I'm not sure.

Note: because I will have to change fuel pumps etc. Thinking very hard about an LS1 Corvette swap instead.
But I have a great little V6 that needs to go in something....got to consider the gas prices....I have a 1996 Tahoe Sport that needs a motor... spun a bearing, could do the LS thing with it....just thinking out loud.

Any advise on the ID of the V6 would be extremely helpful.
