love to see low 12's possibly high 11's.if my vortecs can't do this, then i need to know before i invest money in them.


and by the way if you have something write thats not relate to this post, then don't write it,it's annoying when two people have huge arguments thats not directly related to the topic, especially on someone elses post, if you want to argue, start your own post
I was never confused as what you wanted to do with the crank. Being turned down already meant to me that it was most likely already hammered on in a 383 and it may be fatiqued already. Eagle cast cranks are too cheap to chance the build with a crank of questionable life left in it.

Your Vortecs (STOCK) will make some nice torque numbers on the 406. I wouldn't put money into them such as valves and porting. You will do better putting thtat money towards a bigger head. (190-200cc) Just remember, the higher you build your power band, the more you must turn it to get there. A lot of other factors need to be discussed as to what it is capable of running. It will come down to the weight of the car, the gearing, and the stall. Not to mention traction also. It takes 400hp to push a 3500lb car into the 11's when everything else is setup right.

There was no arguing. Typhoon asked a question that was revelant to cranks and the info I wrote should help you also when you decide what to do for a crank.
