You don't want to go over 450 rwhp. If you plan on heads and cams along with your s/c, you'll want to get the internals forged first. A s/c with heads and cams will almost deff. put you over 500rwhp... depending on what you make for boost.

i think the crank should be forged already. but you still have the powdered rods and the hyper. pistons which are the weak spots. i wouldnt push it past 450 unless you just want to see what it takes to blow it.

So the stock block is okay but i do want to make sure i get forged pistonsa and stronger rods( hopefully the crank is forged already ) but is alluminum forged pistons the way to go and which way for the rods

Thanks for the help

Any forged pistons you get won't be aluminum. Same thing with the rods. Contact a local builder and let them know what you are trying to do with the car and they'll know exactly what you need.

hehe procharger is just a brand name like vortech or paxton, they are all centrifugal superchargers. AKA blowers
