Cam degree issue losing my mind!!!!!!!!!!!!

You definitely have a nice set-up and I appreciate your input.
Al Dicksen (HRD Racing Heads) does all of our cylinder head work but not for free!
I would take you up on that offer if I could.

I didn't say Nick's port work will have a 65% I/E. I just said I expected the mid lift might.
Looking back on my post I shouldn't have said anymore about I/E ratios since I already stated that it was the least important value needed in this case for figuring cam specs.
Can I take that statement back?

My reply was to share with you what the thought process was and why a wide range of possible I/E ratios wouldn't likely change any of the other cam specs.

No one has asked Nick if he is going to have his heads flowed after the port work so you can look at the numbers.
If he does then we will have most of the data and Nick will not have to swing the cam around in a circle waiting to hit a golden goose egg.
What a Mess!

Al Dickson, it doesn't get any better then that! I am not trying to make you guys look bad here, as a matter of fact I agree 100% with what you guys are saying. Its the way you guys are getting there that I am pointing out. You have to remember that someone someday if not already is going to come across this thread which is a great topic that I can't remember seeing posted here before and they won't have all the info to apply it to there combo. They need to know its important to have all the flow's, I/E ratio through all the lifts to make the correct cam choice.

I would like to see all Nicks drive line spec's, engine, trans, gear ratio, complete right down to exhaust. Pic's would be great also. I am interested in what you guys are saying and it looks to be a cool project. I can't wait to see how it turns out:TU:

 

My JKM 600 with Performance Trends Software




Heads off the LS in the Mustang :TU:

Heads wil be checked out to see where theyre at at some point,but im not too worried as i have a pretty good ballapark idea where there gonna end up at with whats done to them
Im no pro at any this but never said i was a beginner as well :Brow:
I learn all the time and the more ive learned the dumber i feel

The cam has been sent back to Lunati,as well as the 1st timing chain
More than likley i will be installing a cam from Ultradyne/Bullet

The specs are looking like something in the
Both intake and exhaust lobes
a-adv duration 288
@050-231
@200-143
Lobe 500" w 1.55 rocker
108* Lobe seperation ,in at 104*
15* overlap

or poss
b-Adv Intake lobe-288*-@050"---231*----@200"- 143*--500" w 1.55 rocker
Exh lobe---adv Duration 296*---@050"-239*---@200"-151*---.523" w 1.55 rocker
109 Lobe Seperation in At 104*
17* overlap


I figure both lobes will be down some on lift ,due to deflection,so they should be OK with stock rockers
Also wondering that ,sometime down the road i may actually build a se of headers(you never know)and ill want a cam better suited for them,but yet still be close enough for the ported manifolds on there now

Or maybe put a stock Stage 1 regrind in it and see how far I can push it with factory type stuff

Heads-Ported mildy iron casting-large valves,etc
Intake -Factory iron-plenum divider milled down and opened up to Performer style opening=will be port matched to heads and may even cut hole underneath Gessler F.A.S.T. style and do some internal work,although id like to back to back that sort of thing
Have a couple spacers ill try room permitting

Suspension-stock appearing
Wheels tires,-Just so happens i received my Hub adaptors today from Mr Steve Reynolds ,so im now on the lookout to get some aluminum wheels to paint black,and pop my poverty caps onto :laugh:
Probably run some type of drag radial, or poss an old M@H sticky type of tire to look more stock?

Anything else i forgot let me know
