Hi All,
I was wondering if anyone has taken a large rod journal 200hp crank and offset ground the rod journals to 4.500 stroke with a small journal 180hp rod journal size to create a 372CI engine..
I have a beautiful AEIO360 large journal non counterweighted solid flange constant speed crank...and was thinking offset ground with 180hp small journal rods with 7:1 pistons would make a nice 9:1 372 engine.
Questions that come to mind are rod to cam clearance and rod to case clearance???? The crankshaft itself already clears the case...
Has anybody tried this ??? What engine shops would have the specs to do this..Aviation engine builders tend to be kind of tight lipped about mods..
This is nothing new...It's quite common in Nascar lower divisions to make 355 chevy v-8's into 363ci V-8's by using this practice..
Any thoughts or names to go to would be appreciated,Thanks, Dave
