Default New to site need help with replacement motor

Guys, I have a 1990 k5 with a 5.7. I love the truck but it is a TURD!! I want more power. I pull a 21' bass boat with it and it's a struggle to say the least. Any and all suggestions would be greatly appreciated. It is my daily driver. I am looking at a turnkey ls1 5.7-350hp or 410hp.

abig84 will become famous soon enoughabig84 will become famous soon enough

wonder if you have crappy axle gears. my 84 k5 blazer had 2.73 gears and it was insanely slow.

my 1990 pick up with a 305 and 3.43 gears pulls my SFA s10 on the trailer no problem. but im sure a brand new engine will definitely help
