Wear on the entire valve train... weak lifters, ware on rockers, ware on valve tips, ware on valve seats, week springs....
It all loosens the preload on the lifter, say new preload is .050" new .. now you may have .020", the wore out lifter doesn't stay pumped up as well...
The fact you stated...
No front cooler, and no room for this one, and I'm not going to put more heat in front of the radiator. This is a large cooler, and fan, I'll see how it handles the temps and go from there for now.
I'm finally getting to my manual to auto tranny swap and have a question...
I purchased a large cooler and fan from Derale with the intent of mounting it under the body.

I've got 245/16 on mine with 2" spacers ....
If you plan to tow anything ya may want to stay with 245....
I'm also going to lower the rear 2" to level it out....
