Re: pretty good cam video
Oh, the problem is "wobbelin" :D Watching that, is like listening to your Barber explain Cold Fusion. I sold those guys a roller cam back in 2014. I wish I knew they had a cam grinder. #-o You can't look at lobe taper or lifter crown as individual specs. For every lifter crown radius, ther...

Re: Solid roller spring suggestions please
What Rocker Ratio? Without the rocker ratio, no one can make an intelligent recommendation. 1.5 ratio on intake and exhaust. Mike, also would you take a stab at what a safe valve lash would be? Thanks Since there's no way to know how aggressive the lobe profiles are, I would go with the ISKY 9935 s...

Re: Is Prof.Blair & Associates still in business?
My understanding is Dr Charlie McCartan has stopped selling the software. But no official announcement. That's my understanding, also. I contacted them a year or two ago, because their software had the ability to take a valve lift curve, and work backwards through the finger follower geometry, to p...

Re: Anyone been able to reach Isky Cams lately?
Well, after making multiple comments on preferring emails, this happens. I just got off the phone from an hour long call with tech support, regarding our "tech@jonescams.com" email. Supposedly someone was trying to send malware to everyone on the server our website is on, so they have shut...

Re: Anyone been able to reach Isky Cams lately?
Kudos, Mike. You and Ed went different ways in making cams, but a family-owned company is always my first choice to deal with. Thanks for hanging in there. I was never the salesman Ed was, but even back in the 50's Ed new how valuable his time was. If you called Isky Cams to talk to Ed, according t...

Re: Anyone been able to reach Isky Cams lately?
Many of us old school guys are "no phone number, no business. I also respect the business owners wishes, if they only communicate through e-mails, OK by me, I am still able to accomplish what I want to do with business owners who still have customer service and a phone number. I know the world...

Re: OE style roller lifters SBC
buy a set of the GM LS7 lifters, and be done with it.
Buy them direct from a GM dealer, because there's a lot of fakes being sold on the internet.

Re: camshaft intake valve closing
Exactly what I'm talking about. 19,000 cam tests?!? Lol If I remember right it was over a 3 year period. Do the numbers, it's physical impossible, especially in the 80s! The funny thing is, my dad was friends with Harvey Crane, and when he went to Crane Cams back in the 80's, Harvey was giving my d...

You won't see that issue with our Hydraulic flat tappet lifters, and that's the reason why they're $170 a set.
