I dont really need it anymore... i was more woundering what it takes to get to higher RPMS and how to beef up the engine. Im really good with my line minus one corner.. i knew the line but i always screwed it up
If i had a scanner i would scan the course map
higher RPMS

I didn't mean to intercept the post and get off topic..... it's just that most people don't know what's involved with figuring out shift points.
The points need to be plotted off a dyno sheet.... and since each car is different.... what might be good for mine might off on yours.
Ok.... higher RPM.... first of all you must realize that stress will increase with the square of the piston speed.
So raising your redline from 6500 to 7000 is harder on the engine than making twice as much horsepower.
This is hard to explain but doubling the power only increases stress by something in the range of 20% to 25% (if I remember correctly)
Things that need to be done to increase RPM....
Factory connecting rods need to be replaced or at the very least heavily modified.
If you want the factory rods I would suggest shot peening them.... removing all marks and edges from the casting process and polish them to a mirror finish.
ARP connecting rod bolts should be used
Pistons should be fine.
Piston pins may need to be replaced
Valve springs need to be stiffer
Valvetrain should be lightened and while your at it you might as well do a multiangle valve job (a shop can grind both the valves and the valve seats in the cylinder head to allow for better flow )
Now your only really talking about 500 rpm but when it comes to piston accleration/speed 500RPM will make a significant difference in the forces on all the components.
