Stock 4v shortblock limits in 2023?

[5.0 Hatch]

So what is the weak link in a 2001 cobra?, the rods?, we have forged cranks right? If its rods can they be shot peened and polished like old school?

Rods and then pistons. Coyote rods are definitely the cheapest and easiest route. I don't think anyone would reuse the stock pistons.

I would say no. And that would be a waste of time being they are cast. Besides a good set of Manley h beams is around 800 not sure the cost difference of polishing and shot peening.

Standard 2v/4v rods I can’t imagine screwing around with, just upgrade em at that point. It doesn’t take much of a rattle to break a stock piston either

I think the absolute minimum upgrade would be a set of gen 2+ coyote rods.

Interesting what years were they and are they a match to our crank and pistons (plug and play sort of speak)

They are a drop in. Do a search, they've been used since boss rods came out which later became the only rod used in the Coyote.

Dumb question.

Have you been told by your machine shop or someone else you can't grind on those rods to weight match them?

Nope
