Listed below are my modifications, dyno sheets, and ET slip. My question is I want to change from a Hyd roller cam to a solid roller cam and the cam companies I talked to have made some suggestions that I am looking for feedback on their suggestions. I am skeptical that these cams will do what I want so I would like you guys to offer your opinions.
What I want is: 6500 RPM peak power, shift by 7000 RPM and a car that will run 10's in any weather. When I called the cam companies to see what they could offer to acheive these goals they all offered the below listed cams and each company said their cam would pick up 30 to 50 HP over my current cam with my combination. When I look at the specs I become skeptical since they don't seem that much different from what I am currently running, what do you guys think. I don't want to make a change and find out it did not perform as advertised.
I do not have some of the overall duration numbers but I believe they will be similar to the howards cam. I do belive the solid roller cams with the shorter overall duration will hit harder from low RPM when compared to my current cam but I am not sure if they will pull any more top end power.
Current cam is: Hyd roller 304/312 duration, 251/259 at .050 with .600/.600 lift on a 110 LCA installed at 106 CL.
Custom cam company: 254/258 @ .050, .620/.620 on a 110 LS installed on a 106 IC
Howards cams: 283/289 duration, 252/258 @ .050 , .600/.620 on a 110 LSA installed at 106 ICL
Comp cams: 254/260 @ .050, .632/632 on a 108 LSA installed on a 104 ICL
