Yup, You're right. But you also don't need a lot of duration on the intake side. Dual pattern cams with wide lobe seperation and more exhaust than intake duration.

Aren't you talking about closing the exhaust a little early, as in less overlap.  Intake will be closing ABDC weather it's 50* or 54* the exhaust has long since closed.

Jake looks a lot better now than back in Jan.  You're welcome any time.

Tim, I think you want to close the intake a little early to avoid blowing Fresh mixture out the exhaust pipe. I'm thinking (careful now!) the blower will take care of his midrange/top end issue, while the advanced cam timing will help him move a fairly heavy car out of the hole.

     You are 100% correct on the 112 to 116 center with blower. That was hard for me to believe at first, I am used to much more overlap, but it works. 

     By the way, Jake is Friggin awesome! wish I could have found your house now!

Chuck, in a word yes. do the intake Centerline @ 107. this should be approx 5 degrees advanced which will help the low end. You'll be good with that I think. Like Tim said the 112 degree lobe centers should work pretty well with your 292. Just make SURE you have enough Fuel and fuel pressure.

Thanks everyone! I think I've got it. I'll double check everything on #6 tommorrow just to make sure. I think I'll even try the intake/exhaust lobe center check just to see If I really have it. Thanks for all the advice thats what makes this site the best on the web for Y's Guys!

The #6 cylinder shares the same TDC on the degree wheel as #1.  Takes only five minutes or less to move the dial indicator from #1 cylinder to #6 cylinder and confirm that the cam lobes are the same.

 Always look at the exhaust lobe centerline as a double check.  That number will confirm the ‘ground lobe centerline’ as well as give some confidence in your numbers for the intake lobe centerline.  Checking cylinder #6 confirms your #1 cylinder numbers as well as giving some confidence that at least two of the cylinders are ground the same.  If you want to really do some checking, check all the lobes.  On some cam grinders out there, this is highly recommended.  It takes only one lobe being off to drastically kill the overall performance of an engine.

Ted, why number 6?

When I started with the advance at 0deg I was having a mental problem with how I did it. Now with the 4deg advance I was forgeting to allow for that. It seems that I have a 4-5deg advance which is apparently in the ball park. I did not compare the intake to exhaust centers. Should I? Chuck in NH

If you purposely advanced it 4* then you should be around 107* on the intake, did you check the exhaust center line?  Set the way you have it would be good for the low end but it is my impression that with a blown motor you can close the intake a little later since you are stuffing A/F into the engine anyway.  most "Blower" cams that I have seen are ground on 112* -116* centers.  If Ted told you to advance 4* I'd go with his recommendation, his experience trumps mine.
