I'm wondering if anyone is running a tight lobe separation angle ground into a mild hydraulic roller cam? I'm primarily interested in applications with less than 220 degress of intake duration at .050. 112 or 114 seems to be the rule on cataloged cams. I recognize that idle quality and emmisions may be the reason for the wide LSAs. Isn't it true that cams of mild duration will still have decent idle quality when ground on a 106 to 110 LSA? Most of my research indicates that there is usually a significant torque increase with tighter LSAs and moderate compression ratios and the wide LSAs are usually better suited to large cubic inch and or high compression ratios and excellent cylinder head flow. Any thoughts? Or track evidence out there?

 

talk to a cam expert, combo grinds some good cams I hear, Nutek does as well. there is much more to cams than anyone on here can explain to you, and if they do, wouldnt trust it since most pay to find all the info out.

for $400 you can get a kickass cam, a true custom grind cam, billet steel (the only true custom cam), there are a few people/places that do them and will know what you need.
