yes that too

 

Well guessing my engine is finally broken in, the difference in power last weekend was very noticeable even towing the trailer up those mountain roads no problem, last year the engine struggled to keep moving me forward on road climbing up the mountains to our destinations

Maybe the rings took a while to seat? I was using the engine as a brake a lot so as not to overheat my brakes

 

that noticeable difference from the 4.0-4.6 ?

 

Yes, all I used was 4.6 crank and rods

I may still do a cam later
