What HV pump? Never heard of that. I've been running the Hesco HV pump in my stroker for about ten years now with no problems in the installation or running it all those years.
Melling M167HVS.
:dunno:
Yes, Melling has a HV pump for both 4.0 and 2.5, same pump.
I doubt you will load the top end and starve the sump on a 4.0.....5 qts. But the 2.5???? maybe, but I doubt that too. They say to smooth out the head and oil returns and paint, to help return to sump.....screw that.
His bearings are pissing and $#!&ting anyway, the least of his worries is flooding the upper with oil.
First I heard of it not fitting though.
