I'm rebuilding a 5.0 for a project truck. My question is how much can the stock connicting rods take. I'm looking to run about 300hpon the motor. I am going to run .030 over forged pistons. I also need to kon how much the stock crank will take. I'm not looking to put much money in it now but in a couple years I may put in a stroker kitin it.

Im gonna call you ONELOWMUSTANG. Soooo ONELOWMUSTANG the stock lowers can def handle 300 hp. no prob. cant beat a stock 302 lower

be careful with stroker not to get the pistons too close to the valves..........

I think it is around 400 to 450 hp safely, at least, anymore may be splitting the block in half

Another question: the motor is out of a '91 lx. What type of camshaft does it come with? hydraulic or solid roller or what? Also, can the stock heads support 300hp?

roller motor. will hold 300 hp.

+1. the 5.0l short block is actually really nice in factory trim. forged pistons and rods stock. crank is cast though like most factory engines. anyways, yes a stock 5.0 short block will hold up to 300hp just fine... the heads will hold you back alot. the factory e7's are pretty much junk unless you have them ported alot.

stock crank and rods should handle 300 hp with no problem.
