Exclamation i got some problems

i know this is the wrong forum but i cant find help anywhere...

i have a 99 tahoe with a vortec 350..one of the piston rods broke off and instead of taking the time to rebuild it since its my only vehicle i bought an engine off a buddy of mine..

its a 350 out of a 78 k10

you'd be better off in the SBC/BBC forum, but i wouldn't do it unless you can disable the knock sensor. even then, the crank sensor is too important to disable, so i'd say you'd be better off finding an engine with provisions for the sensors.

Also the block/crank is a one piece seal as compared to the 78 block which is a two piece seal.. the crank end are different and will need a different flexplate.

You should be able to swap heads ok.

As far as the Knock sensor, the engine controller that does use it input signal. You might be able to take the block to a welder and have him weld a nut on to the side of the block that has the correct threads.
