Motor Rebuild for more RPM
well guys I have searched around the site and tried to research as much as possible but I haven't been able to find much on what i'm looking for. I wanted to ask you fellows for some advice. I'm looking to build a stock bore stock cubed motor. I have been looking around at the rebuild kits. I want to know what I need to let this motor run some high rpms in the 7K range. The cam I have is going to want to rev pretty high. I have stock ported heads. I was looking to run around a 150-200 on it. Would I need forged rods and pistons to run that amount of nitrous safely? I'm looking for some input from you guys that know these motors pretty well. Thanks.

If you want to spin to 7K, ARP rod bolts are a must.
If you want to do a 200 shot, forged pistons are a must, forged rods would be recommended, stock crank might be ok.
You might want to run lighter weight internals and lower tension rings for higher rpms, hopefully someone will chime in as I am not familiar with it.
Wish I could help more.

Launching!
yup, make the rotating assembly as light as possible starting with reciprocating parts and then to rotating parts. that means short pistons as you would need with longer rods, said 6" forged rods, and if budget allows, lightweight forged crank. also pay attention to valvetrain components. they should definitely not be skimped on. cheap parts here wil destroy the entire engine, especially the components closest to the valves. springs, keepers, retainers, and rockers. the valves themselves are a reciprocating part and should be light for better control of their motion. l

actually according to all of my books, lt1 rods are powdered metal which is just as strong as forged rods but lighter and cheaper. if u want a 200 shot go with forged pistons if u want a 150 shot stock are fine just need a safe tune. Get some lt1 books to do ur research..... my local library has them and they seem pretty dead on
