Im curious as to what you guys think would be good starting points for a solid roller geared for nitrous.

Combo will be a 396,12:1,AFR 220 heads,Direct port,TH400,convertor will be selected soon,3.70 gears,27-28" tall tires.
Im looking for ideas under 7k rpm and over 7k rpm (not sure if i can swing dfi quite yet,but it IS in the plans).

 

that sounds pretty good set up so far....

 

How often ya willing to put springs in it........

Something 24x/25x @ .050 on a 112 sounds like a good middle ground for the "7k RPM PCM Dillemma" to me

Even with the DFI I don't think you need to spin alot of RPMs unless you're geting real competitive, and have some strict rules to adhere by. Then you're just tearring up engine hard parts and changing valvesprings once a month. Up to about 7500 RPMs is the most I'd spin most any motor that you don't want Badged as a "Race Motor".

Wants the Specs to my 8000rpm Spring Killer?

 

Thanx Kurtis,75-7600 was around the rpm "ceiling" i was looking to go.
After all it will be somewhat of a "street" engine........heh

 

that setup on the street....your nuts
