looks right to me.
Some here had mispelled his last name but that is his location and correct phone number from what I recall.

Dan Basiley
Can anyone confirm if this is the correct contact information for Dan Basiley?

I yanked this info off of another thread from a couple years ago. I also am confused because sometimes I see the man referred to as Dan Basiley and other times as Dan Baisley. Same guy?
I'm trying to put together a build using a 37G cam and would like to know what the CR would be using his Super stock port job. Thanks...

I just looked it up in the phone book. That is the right address and phone number.

Hi Totenkokopf...................quite by accident I found Crane cams new reference about bigger ratio rockers and how standard rockers give a slight bump in performance coming off the base circle when compared to larger ratio rockers.......but that larger ratio rockers have been proven to give the correct lifts at the valve when comparing valve train geometry.Totenkopf said:looks right to me.

They did not show significant improvements in performance other than Ibelieve they would improve throttle response.
And it is DAN BAISLEY
All the best, Ozzie
Thanks folks. Appreciate it.

I found this quote on the Crane website...........
How does an increase in Rocker Arm Ratio improve the engine's performance?
The lobe lift of the cam is increased by the ratio of the rocker arm to produce the final amount of valve lift. A cam with a .320" lobe lift using a 1.50:1 ratio rocker arm will have a .480" valve lift (.320" x 1.50 = .480"). If you install rocker arms with an increased ratio of 1.60:1, with the same cam, the lift would increase to .512" (.320" x 1.60 = .512"). The engine reacts to the movement of the valve. It doesn't know how the increased lift was generated. It responds the same way it would as if a slightly larger lift cam had been installed. In fact, since the speed of the valve is increased with the higher rocker arm ratio, the engine thinks it has also gained 2° to 4° of camshaft duration.
The end result is an easy and quick way to improve the performance of the existing cam without having to install a new one. See the Buyers Guide section for availability of increased ratio rocker arms. Remember, whenever you increase the valve lift, with either a bigger cam or larger rocker arm ratio, you must check for valve spring coil bind and for other mechanical interference. End quote from the Crane website.
It seems like a reasonable thing to do.
All the best to you too!

Sorry to steal this thread..............just easier for this old fart to grab the atention of the other guy while I can still remember what it is I want to say....... I think.
Hello again T, yes this desk top software I have definiteley can not account for actual results for several reasons...............it was just that when I noticed you had different ratio rockers I plugged several options both up and down in scale into my favourite build and achieved a performance increase that would not be discernable............no increase in torque and a barely noticeable increase in the top end.
Shows the same with lift scenarios...............to get larger than .580 lifts to work...............the heads have got to come into play and I used to spout about a 1.7 inch diameter intake port, now I am finding a 1.66 diameter port gives a far better bottom end with the correct sized intake valve and cam choice................but, but, but, the top end does drop off somewhat.
All the best, Ozzie

The rocker ratio change by itself is a subtle improvement. A little more lift, a little more valve open duration. I was after more upper end performance without losing the bottom end gains. So, combined with the cam key reversal and the reworked throttle body/intake, I'm getting the changes I was after.
With regard to the intake port diameter, Otto was just showing me yesterday on some S&S SA heads for his next race engine that it's not just diameter but shape of the port. I'm not sure how the desktop dyno can account for shape differences.

Yes I believe that port shape gives impressive gains and also chamber shape in burn rates and VE.Totenkopf said:The rocker ratio change by itself is a subtle improvement.

The Engine Analyzer will not help with shapes at all..............and for me without a flow bench and dyno to see where the improvements lie it would be no point but for you and Otto I believe the Port flow analyzer could possibly assist there............and shorten up your bench time with port design...just a thought..........would save on heads.
What is important is after welding up the ports to heat treat the heads to remove built up stress and then do the porting and not many guys remember to do that...............no doubt Otto knows this already.

Thanks for the link JMS!JMS said:
I talked to Dan yesterday for about a half an hour. Seems like a great guy. He answered my questions in a way that a dumbass like me could understand.
I forwarded him my parts list and he's gonna look it over and get back to me with his recommendations with an eye on saving me a few dollars. I'm dealing with a reputable guy up here who generated the parts list and while there is some good stuff on there, the build is going to cost more than what I'm comfortable with. Currently, this is an open can of worms. Trying to get the lid back on.
Thanks again!
