Here is my result, although it's a 2.8 it is using -5 snails. Basic spec is...
- 2.8 (9.0:1 comp)
- -5 huffers
- E85
- Twin 3 inch exhaust
- heavily modified head (Naprec chamber modified, 1.5 mm OS in and out)
- cams are a 260 at 10.85 mm with quite an agro ramp rate. The duration at 50 thou is 232 degree's which is the same as Camtech's baby drop in but with 1.7 mm of lift more.
How hard do you want to rev it?
Where do you want your curve to be strongest?
Whats your tolerance to a lazy bottom end? 2.6/-5's isn't particularly strong sub 5000 RPM.
