IMHO, a mechanical roller cam will make more HP than a hydraulic even if all the cam events were the same just because you don't have all that oil pressure pushing on all the lifters.
Only thing is, mechanical rollers need springs that are a little more $$$ than the others and many of the folks building stuff nowadays don't like the idea of checking valve lash ever.
I grew up with it so I don't think it's any big deal.....

 

something isnt right with your combo. that combo should be at least 350-360 with the auto

 

i think he knows.lol

for all the money he has put into it he could of had a 600+ hp 408 or something.

 

Mike, with the solid roller you can take advantage of heavier springs and then run the ramps much more aggressive open the valve faster and more lift and close it faster if needed. so yes you can make more HP with a solid roller.

 

yeah when we talked friday night question more so develped into afterwards...how much of a difference?? I'm weighing is it really gonna be worth all the work to change it?? hmmmm dunno???

 

I guess it comes down to what are you willing to give up. drivibility the car running snotty down low are you willing to spin to higher RPMS. you know how it goes sometimes you have to give up something to gain But I think you could gain a good 30 HP maybe even more. with out giving up to much or give more and gain more. Maybe call Comp. Cams Tech and talk with them they would know more about it then most of us.

 

thanks John!! Gives me something to think about over the winter, I'm to worn out messing with the car this late in the season but depending on how it runs in 2 weeks , i'll hAVE something to think about
