Re: 91 k1500 4.3 to 5.7 motor swap?
35 hp and 70 lbs-tq is big gains. And like I said, there is no comparison to a TBI 4.3 to TBI 350 as far as performance.
And there is bunches of hp ratings for those engines. I've seen as high as 160 for the 4.3 and 210 for the 5.7. Either way, you could def. feel a difference in 35 hp and especially 70 lbs-tq.
