5.7 350TBI 5.7 350TBI bolt up

[Mechanic in training]

I have a 92 GMC Sierra 1500 with the 5.7 350TBI currently bolted up to the 700r4 transmission. I need a new engine & I found one it's also 5.7 350TBI  bolted up to a 4L60e transmission out of a

95 Chevrolet Silverado extended cab . Will the 350 out of the 95 work in my 92 ?  Or will I have to change ECM. Wires ECT since one is cable & one is computer . Please Help .

So it will bolt up no problem to my 700r4 even though it was previously bolted up with 4L60e? 

 

[riverbanks]

Yep,you're good to 99 or so, as long as it's a 5.7,ls blocks is when bolt pattern changed

Thank you so much.  Can't wait to swap them out 

& have it back on the road..

Once I get them swapped out , I will definitely post video .

Right on, keep them Chevy's rolling,now if you're truck will last,body wise,96 to 99 vortec fit,a increase in h.p.,but you have to get a hybrid intake,vortec heads to t.b.i,just something to think about

I will definitely check into that . Again thanks for the help..
