12v roller rockers

[longhorn859]

Being a stock ratio, I assume there is no real power benefits.

did someone really waste the time on machining and designing this stock ratio set? if so, someone please slap them in the head. thats like wipeing before you poop. just makes no common sense to me. now a higher ratio set, thats a different story

Maybe others have had different experiences but I never have heard about the stock rockers breaking.......

I was wondering if the needle bearings would cause less drag. In turn more power to the ground?

Would be such a small amount, if any it wouldn't be noticed.

Change the cam if you want more lift. Changing the rocker ratio to gain lift is welfair.

Of course when your looking for the last ounce of ramp rate, a higher ratio will help.

I spent the better part of a day talking with the builder of these rockers. he is so far advanced then any one on this site in pulling motors it’s not funny
The ratio is everything. I would run 1.90 to 2.10 to 1 ratio on 12 valves.
The current 12 valve heads like big lift. And this is only measured on a pressurized flow bench.

he does his own billet rods heads and fab

here is their face book page

any some of you wonder why the people with any real know how will not post.

That's a real old drag racing trick, before dual profile cams. We're talking the 60's. There's just no need for it. A custom cam can be had for under 750. I'd deff add stock ratio rollers for the extra G-note.

No one is saying he doesn't do good work. The main discussion was the op rockers being stock ratio.

damn! that's a sick puller engine!

Holy hell!

you tell me how the math adds up with the heads wanting .750 to .800 lift at the valve with a only 240 degrees of duration on a 54.5 mm cam core . I currently go .425 lobe lifts now , and on my 57 mm cams I currently go .475

and are designed by head flow requirements valve lift , and then you work with rocker ratio, and then design the acceleration rates in to the cam to fit that ratio.
Maybe I need to charge more for custom cams. Every cam I do is ground after we decide the application. I do 20 a week like this

Stating a fact, mr know it all. Please educate us

Someones a little performance insecure.

[ahale2772]

is there a standard procedure for a douche response?

I assume it goes something like...

1) credit yourself
2) insult
3) attempt to impress
4) spout numbers
5) pictures of billet stuff

Robbie called me after talking to you about these rockers and told me Ure the man I Need to make my cam. We will be talking soon. Thanks for posting.

Say what ya want about comp but he sure does take good pictures!
