Hi Folks
All the calculations show that 42 is great but it also looks like 36 should work also. The duty cycle will be higher but most of us only run our car at the track for a couple of seconds with a high duty cycle.

i made 550 rwhp in my 408 on red top 30 lbers, but they were at there max, i ended up going with green top 42 lbers, and my duty cycle is 85%, my vote is green tops, you can them for 254 brand new on summit racing website, they are the ford motorsports 42lbers

This is really odd since there is one guy in the Fuel forum that shows that he had 30# SVOs on his 370cu.in motor and he said they maxxed out around 4500rpm. That just doesnt seem right.
Another person told me the 30# SVOs like for example on my motor would max out around 4500rpm, I dont see how this is possible when I put down 440whp and my stock 02 injectors were at 95% Duty Cycle.
Im planning on putting on either 30# svos or 42# but not sure.
