i need to know what the engine spec's are for a 181 gm 4 cyl engine. mine has the big valve head if this makes a difference. I,am planning on installing it in a river jet fishing boat and I need to know hp,torque and rpm's in order to pick out the right size jet pump the engine will drive. I really appreciate it.

bob in tn.

Here's some.

WOW MINE DONT HAVE ANY OF THE FANCY STUFF, JUST A GOOD "OLD" POINT TYPE 181 AND I,AM GLAD IT DONT HAVE THE NEW STUFF.
THANKS
BOB
