It costs the same if not less that to build an engine of equal power. I’m running their iron head 350 in my k10. It makes 387 hp and 414ft lbs of torque. My stepdad is running a BP 400 in his camaro makes 508hp and 517ft lbs of torque we bought it for 5,199 2 years ago. You couldn’t build one to make that power for that price. On top of that you wouldn’t have a warranty.

I have the BP 383 and it leaks oil from nearly everywhere.

@@bobsilver3983 then call them

@@yamahaguy1732 Max labor warranty is $500. My engine needs to be pulled and all new gaskets installed...$500 is nothing.

@@bobsilver3983 why don’t you pull it yourself

56psi at idle, exactly what my BP 350 does. Maybe u r looking at the small gauge thats not connected.
