Re: Camshafts almost done
You probably have your valves by now but was any thought given to using some cut down NASCAR valves. They have gotten pretty slick about valve design and have used items for sale at real reasonable prices. Rob Dewile has put togeather a couple of sb2 motors with used NASCAR stuff and could give recommendations on who has it and how to get it. I think one of the motors he has cost him about 5k-7k using heads that probably cost the NASCAR team 25k plus. Fastlane was at 800-875 hp on the 431 motor not sure on his cam designs.
I lenghtened the prime pulse time on the p-type start cycle and it seems to have solved the start problem. You coming to the gathering? Tyler

Re: Camshafts almost done
Greg,the issue with telling is there is no loyalty anymore.
What i'm saying is if someone paid for a master grind the company will sell it to whoever. If someone put out money for the master grind and more money and time for testing is it fair for the guy who put out the money/time. If the company was smart they would not charge for the master grind this way there name would be posted all over and could've made more money in quantity sales instead they get a master grind charge and that's it. If somebody cuts me a check for the master grinds i will tell you and then you post the info since you paid for it. A little story, i know who cuts cams for SGC i decided to call and ask them to cut me a set of exhaust Stage I's he told me i had to call SGC since they paid for the master,i could not believe my ears and what i was hearing i finally found one person that was in business with integrity and loyal to his costumers. WOW I wish they were more like him. I called SGC no reply i guess i will have to pay for master grind for my Stage I's unless somebody sells me there Stage I exhaust cams Greg?? Pete

Re: Camshafts almost done
Pete, thanks for the explaination. Didn't mean to be an a-hole about the secrecy surrounding various cam grinds. It is a business. I for one have no interest in doing cam design but I do understand protecting cam designs for different applications. They are at the heart of a good result. As I understand it, almost everyone that does cam design and testing has a cam grinder they trust. I was more interested to know who the pros ( yourself included ) use to grind cams than to know design info. I presume you send your designs out for grinding. I say that because it takes a bunch of machine equipment to be in that business and most tuners I know don't want their money tied up in equipment that would get limited use. Cams and cam design have always been a bit of an enigma wrapped up in a blanket !!!!!! We less gifted techies know when they work and when they don't by the neck snap factor !!

Re: Camshafts almost done
Finally finished. Almost too pretty to run...
Grinding the heads to clear is no fun, though! Todd |
