Here's a cam question for you. Is this too much for the street?
Dur at .050 242/252
Lift 525/540
Lobe center angle 110*
Intake center 106

Skip

 

I take it its a LT1 correct?
With that centerline your not going to make any vaccum at idle on 242/252 duration... it will need lots of timing at Idle to work.
And if its a auto your going to need 3500 stall at a minimum which is no problem on the street if it still has lock up...
...410 gears a must and it should make power to 6800+ rpm if the heads are good.

I'd rather see the centerline on a 110 with 4 degrees of advance ground into it... That puts you on a LSA of 114. Idle vac will be much better and you'll only drop the power band down a little.

If nitrous is in your plans for sure go on a 110 CL.
If big nitrous is in your plans go on a 112 or 113 center line with 2 to 3 degrees of advance ground in it.

City driving will have nill millage but HWY mpg will be at least in the 20+ with no problem!!

I run 246/258@ 50 on the street and pull 11 inches of vac in gear @ 950 rpm... on a 113 cl with 4 degrees ground in

 

Funny you should mention the nitrous. That's in the plan too. I currently run a 3200 converter and 3.73's are going next spring.I'm not sure but I think the cam is ground with 4* advance so I should be good to go? I did a DD2K pull and it makes pretty healthy numbers with stock heads. So you think it's still fairly streetable? I'm thinking occasional 30-50 mile jaunts.
thanks for the come-back!

Yes your correct reguarding that cam having 4 degrees ground in it but its the 106 CL where I have the issue. It will have no bottom end and all top end. Go with 110CL with those lobes with 4 degrees ground in...
...power will come on sooner and it will feel much better on the street. It will LOVE NITROUS!
Hell I drive mine to Stanton from Clarkston with No issues what so ever, drive it all over in the summer on weekends with more cam then what your looking at doing.
You'll be ok and when your ready to tune it PM me I can help you in that department.
One thing thats a must do tho is getting a AFR rev kit for it and the good Comp cam "R" lifters, These are a must on hyd rollers larger than 240@50.

Whos stuff is this?
And Have you looked at the comp Extreem lobes?

 

It's a Lunati cam. I downloaded a bunch of cam profiles for DD2K and have been running them through to see what I can do with "stock heads" I'll certainly take you up on the offer to help me tune it. You wouldn't be interested in doing the install would you? I haven't got time seeing as how I work 6-7 days a week most of the time.

By the looks of the lift, it's probably a flat tappet cam you're using in DD unless you limited the lift and changed some of the cam specs yourself in the program. ANY of the Comp Extreme Lobes or any roller cam could squeeze a lot more lift than what you have shown into a cam like that. My flat tappet pos cam has that much lift with much less duration. Goodluck! And like Jeff always says, the tighter the better when it's on the street. LOL

 

Lunati 50126 is the cam. DD2k file I downloaded shows it as a roller. I didn't change any of the cam parameters. It is listed as a "Bracket" cam. I haven't found any info on Lunate's site about this one though. Maybe someone was dreaming up some scenarios when they made the file. But it looks like a fairly inexpensive way to make some decent power even without headwork.

I wouldn't mind if someone could actually clue me in on a few things about cams though Like what effect on hp/tq does long duration have, how does LSA or LCA effect hp/tq, What does Intake center angle do, etc... And what to look for in a cam when running nitrous and WHY
Thanks for the help guys

Checking out the cam manafacturer sites is sometimes worthwhile for info. The "Advanced Tech" forum has had some worthwhile threads also. Rich Krause has taught a little bit to whoever has asked in that forum. Do a search and you'd be suprized.
