T/Anks for the replies so far. I'm getting educated... more duration is obviously needed for more CID, especially a longer stroke such as the 4".
The LSA degrees puzzle me... 106, 108, 110, 112?... having vacuum is needed for my power brakes (during low rpm and off-throttle braking during racing). I'd prefer not to have a rough idle, somewhat smooth... a little lumpy is ok.
I don't want the cam's power band to fall off suddenly... I need it to be strong and wide between ~2500-3000--5500-6000... lots of mid-range.
Solid cam would be ok but I'd favor hydraulic simply because it will be
street/highway driven most of the time... actually... going to/from the road race tracks.
I've tried uploading the CompCams CamQuest program... won't load.. and they don't answer their phones or e-mails.
This is why you need to call someone NOT named Comp who will help you. LSA is a product of all the timing events. You're not going to learn it all from a forum.
Call several cam grinders. Write down all your questions beforehand. Take notes.
Most cam grinders will spend the time with you to explain why they do what they do. I prefer to use small companies, where I get to talk to someone who isn't paid to sell cams from a catalog.
