Ok listened to a lot of mombo,jumbo from u guys but ,I think I know best from reading gobs of stuff from people who Know!!! I'm going to try a hydraulic cam first,tried many progams,the camquest,quarter jr and others and if I go up higher than 260-265@050duration the solids definitely have the edge,but at a lower duration they don't make much more power than the hyd but then I'm not wanting to go any higher that 6,000-6,200 tops So the winners are the XE295HL comp 251-257 dur@050 with 565 lift or the 60305 Lunati which is 242/252 dur@050 and 533/552 duration probably going with the Lunati as I love them and theyhave been good to me for 30yrs,plus love their Micro Trol lifters,if I don't make 565-600 hp then. Next year I'll get a set of Mancini Harland sharp copies for 469.95 and try a solid or Hyd roller,do'nt want to go any higher than 650hp and don't think I won't make it because I do everything right, MY last 406 sbc made 625hp with 285cfm heads and my one before that made 675hp with a set of stovck oval port truck heads with just 2.19 and 1.88 valves instead of 2.07 and 1.72 ex BBC heads and big heavy trw pistons and 12-1 compression..So I just want a vote on the Lunati or the Comp cam XE that's all No other comments please about not enough head flow,my engine WILL make it with 285@550 lift
 
"Next year I'll get a set of Mancini........."? Does that mean you're running stock rockers now?
 
I'm not a big Comp cams fan. IMO Lunati cams are of a higher quality. My vote goes to the Voodoo. Have you looked at the Lunati 60313?
 
yes may give the stamped rockers a whirl,as they are set up right! spaced to be right on the valve stem,shimmed under the shafts for proper height,,and have had custom pushrods made,they are as light as possible and I have low pressure springs 120 on seat but only 340 open,so see how it goes because if I go adjustable might as well change springs and go solid or hyd roller,but I want to prove everyone wrong I want 600hp with a hyd flat tappet
We will see how it goes......
 
lookin all around for the 313 lunati then I find it ITS A Hyd Roller!!,don't want to spend 100$ springs,460$ roller rockers,300$ for the cam,250-450$ for the roller lifters! For 1300 I could run a street solid roller and make 700 hp easy,think I will go with the 200 bucks for the flat tappet cam and lifters (Micro Trol) and save the 1100.00 and give up the 20-25 hp. I think the solid flat tappet cam would also save me about 500 bucks and make more power than the Hyd roller. Personally I think that the hyd rollers are the biggest waste of money there is,the lifters are way too heavy, they fall off at 6000-6400 rpm and the good lifters are over 600 bucks ..I'll go with a Hyd flat tappet followed by a solid Flat tappet w/tool steel 74gram lifters,then forget they invented a hyd roller and go to a street solid lifter,and lastly go to a full race solid roller,a solid will go 7000rpm and solid roller will pop before over reving.....how much more HP do u think a 242/252 hyd roller will make over a hyd flat tappet 242/252 the lift is neligable 552 to 565, peanuts they will both drop off at 62-6300 rpm waste of cash to me..........

True yeah.

Well, "because", and I quote him, "I do everything right," I think he should pick out his own LunaCompti camshaft.

At least we know it will be done right.

Yes with no mumbo jumbo.
 
:popcorn:
:lol:
And Tuesday's weather is sunny, warm, rainy in the evening....
 
I'd spend double on stock cam before I'd ever use those flexi-flyer stamped rocker arms.
Why get crazy with big lift and long duration cams (and the required springs) then give it all back with deflection? S/F....Ken M

Ya no ****..live and learn!!!
 
FWIW, IMO, its more of a lift loss issue even before I think about anything else. The standard ratio rockers are less than advertised.

An upgraded rocker provides an accurate ratio with increase strength and stiffness. Also zero heat cycles.
(Longer life)
I beileve it should work it's way into the budget. Somehow, someway, they should make an appearance. I do realize this is a tight financial issue with retirees. To this end, Hughesengines has some reasonably priced roller rockers.

Edit to add the below;

I run mumbo cams all the time. I don't have any trouble getting the power I need from them and they're cheaper.
 
For me it's Jumbo. If a little is good, a lot is mo' betta.
 
Not according the you but mumble-jumble-ire is interesting. It's slightly stiffer and hotter. It requires a bit of extra lube spitting on it.
 
OK, I read through the original post. You have a 406. That's all I got out of that. How can you (we ) pic out a good cam if that's all we know. Fill me in.
