I have an engine rebuild class, what kind of power will I be able to run if I put forged pistons, and arp main bolts in the motor??

gain from forged pistons?

I'd like to make about 420rwhp and would like to not spend 500$ on connecting rods if possible....
How would a set of 2001 cobra rods do with some forged pistons...I have a set and thought of using those....

Do I look like a :taco: in this picture?
you are insane if you don't put the forged rods in there if you are going to take the time to do the pistons... but umm, whatever... I guess you could get higher compression pistons and bump up the hp...

I believe that the '01 Cobra rods were the same as the GT rods. '03-'04 rods would be good but you could still do better. I believe the '03-'04 rods are aftermarket but knowing Ford I'm sure they cut corners to save $.50 an engine.
Also, you probably won't gain any power at all from just the rods/pistons, you may even lose power depending on if their forged and what material they're made out of.

you will not gain power from changing to forged rods/pistons alone. however they will allow you to safely make more power. if you put in dish pistons and do not supercharge the motor then you will lose a substantial amount of power because of the loss in compression. the stock 03/04 cobra rods are very good. they are Manley H-Beam rids with ARP fasteners. i jsut dynod a buddies 04 mysitchrome and he made 581rwhp with the belt slipping pushing 21lbs of boost on the KB without taking off the valve covers.

No, SVT used Manley H-beam rods and Manley dish pistons for the 03/04 Cobra motor. There are pleople making close to 1000 HP at the crank on a New cobra motor with no problems at all. The 03/04 Cobra motor is the best motor Ford has built IMO.FallenPhoenix said:

if you dont do rods then there is no point in beefing up anything else. for a solid build just get forged H beam rods from manley. if staying NA, you can get domed pistons to raise the compression a little. if you want to run boost, get dished pistons, make the compression ratio 8.5:1 and you can make some excellent boost.

In MM&FF, they had an article which explained for every point of compression gained/lost you gain/lose 4% HP....

If you are gonna have the engine out, you had better do both the rods and the pistons, Im sorry you dont want to spend $400 to $800 for a set of rods, but it would kind of suck if you spent all that money in balancing the crank to the new pistons, new bearings, gaskets, labor etc.... and you threw one of the stock powdered rods, you would be at square one again, Do it right the first time or dont do it at all. If you dont have enough money to do it now, wait and save. Horsepower is cheap.... reliability is expensive....
