5.0 GXI Cracked Block Need Help Sourcing New Parts

stresspoint · Jul 9, 2023

i would just put the stock truck motor you have found for 500 , bolt it all together and run it till it blows , .
meanwhile chase a 350 4 bolter , ditch the fuel injection and build a 450+ hp motor that is ready to bolt in when the time comes .
my bet is even with that stock cam (hope it does not suck water up the pipes), running the 5.0 EFI ,that 500 bucker 5,7 truck motor will outlive the boat.

Haha i like that idea. Basically what my intent is at this point. Could my transom and SX-M outdrive even handle something like that?

the transom on a sterndrive is there basically to stop the water flowing in

,it carries very little if any engine loads like an outboard so the transom should be just fine with a big Hp motor.
i am not familiar with the SX-m drive so i wont comment on that part of the equation.
I'm sure there are people here that will point you in the direction you would need to go if mods are required to run hp on the drive you have

Need some more info of the truck engine you are about to get? What year and what year is the boat?
Do a quick search of GM 5.0L "Reluctor Wheel" 24x or 58x... Black (24) or Gray (58) Crank shaft Sensor which is part of the timing system in which could be an possible issue.
