Now that's what i want to hear RylisPro lol's , it'd be interesting to see your dyno print out .
A while back i purchased the PipeMax software to figure out what to make for a stock 6.1 ( nothing available in right hand drive ) 1 3/4 worked out good for mid range tq and upper rpm hp .
Now when i type in the numbers for more Cubes , rpm , cam , valve sizes . PipeMax comes up with 1 7/8 - 2 1/8 .
just seeing what real results people have .
