    Predator 60363 or 69730, why?

    Well guys, I need your help choosing a predator since my briggs blew up today. Which of the two is better and why? It will remain stock for now. Thanks

    I like the non Hemi myself...
    Seems the Hemi blocks split way too easy...
    The non Hemi also comes with 27/25 valves, in stock form the RTC 6,8 and 9 heads flow better... In stock form!!!

    You can use a clone cam in a non Hemi without issue...
    The non Hemi cam is .004 larger in circumference... The factory service limits are well above this...

    I like using a Honda crank, Hemi flat top piston and Honda 3.403 long Rod... Makes for .005-.008 pop up and use a .045 gasket...
    Throw a dyno 308 cam in with 1.2 rockers, and dual springs feed it alky with a gx390 carb, and hold on...

    Thanks for the ideas. I did buy the hemi and for now it will remain stock but I would like to gain some power without opening the engine, it is used in a converted electric to gas golf cart the my son was given.
