ok as many of you may remember i got the ford racing cam so i was wondering what can expect out of the car in terms of power and what not in my 289 i have a 625 carb weiand action plus, ported heads, bigger valves and headers here is the link to it M-6250-A312 i just want to know cause i am gunna install it next week if any of you have desktop dyno that would be great i know its not accurate but it gives me an idea

 

275-300.

 

cool cause i got the 1.85int/1.55exh valves and all that other stuff so i wanted to know how it would react with that new cam oh and i am gunna add a windage tray which is like a 15% increase in hp or something correct

 

ya right about 300

i tried to find a torrent for desktop dyno but no dice

 

there is one thing i cannot find out with that cam and that is what is spring do i use the ford racing ones i soppose but which ones should i choose cause i know too light a spring and the piston closes the valve and too strong it flattens my cam or lifter and do i want rotating springs or no

here are the ones i have looked at

Ford Racing Springs
Blue Racer Springs
Comp Cams (249-940-16)
Edelbrock (not the rpm ones)
