How hard can you spin a 402 with texas giant cam, H beam rods with ARP rod bolts, and stock GM main bolts?

Till it stops making usable power? What's the point of spinning it higher if it isn't making power? Look at your dyno sheet and see were the power starts to fall off and use that as a refrence.

The 346 cube motors are typically good to 7200-7400 rpm with ARP rod bolts for good measure.

Its in pieces now.

But you knew that already.

The motor istelf was as tight as a drum. And didnt leak or burn a drop of oil.
I tore the motor down in order to lower the compression. As well as diagnose a "Valvetrain" problem. NOT a motor problem. You fuking moron.

But you knew that also...

I wish I could have said that about the motor that YOUR tuner ripped me off and fuked me out of.

Dont you remember??? You know, the one that took me for 23 grand but sold me a busted *** 1997 LS1 that leaked oil EVERYWHERE..(All the while, passing it off as a practically NEW forged LS6.) But then tried to cover it up by sending me ANOTHER busted *** motor.

BTW, Heres the graph of the motor that you think was "Bad"
Do you want me to post pictures of the car in Pamona at a show a day BEFORE I pulled it apart to prove to you that it was running/driving??

Again, UNLIKE the condition of the last motor..

Quit swinging off the ball sack of your tuner. It makes you look like a bitch.

For those of you who dont know. This troll follows me around and tries to make things out to be what their not.

My "tuner" is Charles Williams, unlike you, I do my own work. In addition, I call a spade a spade, and the post above just reaffirms who you really are. As time elapses, your reputation will precede you.

Oh, if you feel that inadequate that you need to "prove" something to me, knock yourself out!! Can we say little p.p.?


So your engine is in pieces, sucks to be you.

the Tuner you speak of has never tuned my car...... last time i checked charlie williams tunes my car... quick question who set up your valvetrain, as far as i know your cam isnt radical, so who ever set it up must of really been off the ball...
