Motor swap???? lt1?? vortec 5.7??

[draggin86]

Hey guys i have an 86 c10 with a 305 i believe it has a 700r4?? I'm not to sure.. anyways its on its last limb.. I'm not to fond of the motor so i think its time for something new! i have a 5.7 vortec motor out of my 98 silverado sitting around... it is a good motor it does have some miles on it.. has anyone swapped this motor into our trucks?? if so how did the wiring go?? i was also thinking of doing an LT1/4l60e swap it seems like it mates up well and parts are readily available for the swap.. i think i would need a tale shaft for the speedo a radiator out of a LT1 equipped vehicle, electric fans etc.. i would probably use the stock sending unit and fit it in the c10 tank.. any input would be awesome!

Thanks Guys
