i had a 304 with just 1.5 RRs. My cam was made for a stock tune. The 503 cam works well with ported heads, intake, springs and 1.6 rrs. Search through LTxtech. Youll find some info on what they run with it.

Ok thanks

any cam you get aside from a CC304 cam will need new springs. and it will need the RIGHT springs.

Any cam you should get springs for it I wouldn't trust the stockers with anything bigger. Also i am partial but i still say cc305

I got the short block from sucidleracing took it apart monday and cleaned the pistons today and found the exact same thing wrong as my motor the space between the 2 comprression rings on piston number 1 is broken I mean I can take a 3 inch long piece of piston skirt out anyone see this before? Both motors same problem both ran when pulled. Idk

well atleast the rest of it looked better then your motor lol

True that

then swap out from your motor piston number 2 rod and piston. get a ball hone an hone the cylinders get a new set of rings Dont use the old ones at this point. and by rights if you take the rods apart/take the caps off your supposed to get them checked for size. you should be alright its not a 10k rpm screamer but just keep that in mind. i usually check them myself by getting soft jaws for a vice. clamp the rod in the vise snug enough you cant budge it but dont CRANK down. re torque the cap back on to spec. and then check the inside diameter for out of round. usually they will squeeze in near the bolt areas. if they are too tight you will need to get them re sized. honestly you should have left it together and just bolted it in.

also look it up but depending on year the rod bolts were not reusable.

Yea I am gunna replace all the rod bearing so I'm gettin them measured for proper bearings and I figured I could get 8 good pistons and rods out of the 16 I have

yeah thats what id do. just weigh them to make sure they are close in weight for balance.
