I have a stock bottom end H/C/I 02 SS M6 with around 55k im currently pushing 438rwhp to a 10-bolt(the new rear is being built)When will I start running into Probs. as far as my bottom end holding up? How much can I spray safely,how should I (wet,dry,direct port?)Thanks for the help................

 

there is an exact sticky in this forum thats titled "how much can my bottom end hold". Maybe that will help answer your question.

 

It all depends on how good your tune-up is. I've run 350 through a customer's cam only long block, and is has hundreds of passes on it. Not to mention, the car is his only form of transportation.

 

OK thanks,,,,,would there be any real advantage going direct port over a regular wet system?

 

Tunability.

 

 

 

The sticky is full of mis-leading information.

 

we had a heads cam car with 400 on it......never hurt a thing....if u can read plugs and keep ur bottel pressure right u should have no trouble
