Are you sure the duration is 265 at 0.050 and not advertised?

Duration is how long the valves stays open, the longer the valves stay open the more your power band moves up,also the more duration the better it will sound.
Lift the more lift you have is also more air you move and fuel you move also. with our cars we need about 268 to 272 dur advertised and 500 to 550 lift. 500 lift with stock head 550 lift with ported head.

From what I've gotten from this thread is that with these Cams.. You take your stockers out and simply put these right in there.

Yes but if your going to do it might as well throw in some new lifters and you will need springs,you will get coil bind if you dont change your springs.

The duration listed is advertised.

Got the pricing for the cams...

Cams: $450, Lifters: $275 & Springs: $317. Will be the regular price.
For a total of $1092

GROUP BUY PRICE;
$660 for everything.


Saving you $382

It is recommended that you change the valve springs, as Scott Allen said, to prevent the spring from binding.

We have customers that have our other cams installed and didn't change the springs and havent had a problem, but it is recommended.

Thanks,
JBP

I'm guessing these aren't going to work well. The lift doesn't seem like a lot. Not only that, but if these cams are for LSJ AND L61 heads, then we still have the issue with the hex key on the LSJ.

thanks for the info.

Cams look like this

Duration @ 0.050”: 265° Intake - 265° Exhaust

Max. Lift: 0.0465” Intake - 0.0465” Exhaust

Center Line: 233°

this isn't looking like 500 or 550 lift.

Stock specs for comparison....

Stock:
Intake Lift: 10.04 mm
Intake Duration @ 1mm: 196.50
Intake Centerline: 100 degree

Exhaust Lift: 10.04mm
Exhaust Duration @ 1mm: 191.70
Exhaust Centerline: -115 degree

Stock LSA = 112.5 degree

After the 400hp mark GM used cams with 222 duration @ .050"

Why are you offering solid lifters if they are not needed?

I'd like to see something that would work well with a ported head, thats the best combo anyway, its dumb to get new cams and replace valvetrain parts without some type of head work for better flow

Seeing as they are included in the group buy for practically FREE, you're getting solid lifters that you can either sell off to offset the price even more or have a full solid valvetrain capable of extended RPM usage.

Think about it, Billet Steel Camshafts, Solid Lifters AND Valve Springs for $660. If you turn around and just keep the camshafts, you can sell the brand new springs and lifters for $200 easy and use that to reduce the price even further.

There's some interesting questions about dyno results. As that is most likely what is the determining factor with these camshafts. Obviously we have some idea of what the gains will be, but its all up in the air at the moment until we get a tester.

We're going to open up the group buy today seeing as we're having the prototype grind made and the testing is in order. Even though testing hasn't even begun, there's always people who love to get a jump on things so feel free to step up to the bat and enter your name for the group buy. Again, this can only materialize with at least 10 commited individuals. So start signing your interest and like the last group buy, start sending some dough.

Here's the pricing Informaiton again for clarity:


REGULAR PRICE

JBP LSJ Billet Steel Camshafts: $450,
JBP Solid Lifters: $275
JBP Valve Springs: $317

TOTAL: $1092



GROUP BUY PRICE


$660 for everything!! (Camshafts, Lifters, Valve Springs)

(Savings of $382)

So this is a direct bolt in no mods to make them work. so i can just take mine out and put these in.it Before i send any money in i want to see dyno sheets.Id also want to see a better profile,because i think these are to small.The stock lsj head flows 261.1 cfm on the intake at 500 lift and 149.1 on the exhust at 500 lift.And on a fully ported head the intake flows 303.3 cfm at 540 lift and 208.5 on the exhust at at 540 lift why not make a cam that works best like a stock head a good cam would be 500 lift,and 540 lift for people wanting or got a ported head if i was going to buy a cam id want one thats going to work with what or heads flow Here is a good cam spec ill throw at you guys.

stock head
268 dur adv and 500 lift

ported head 272 dur adv and 550 lift

These would be perfect cams for us people wanting more like a street /strip cam here are some specs for them also

280 dur adv and 570 lift

i dont want to buy a cam that i wont even here a diffrence over the stock cam and with just more lift that would only be half of the performance. duration aint going to hurt us it will help us a lot . so why no make it happen?

If thats the only cam you are going to offer,then how about a diffrent ratio rocker to give it more lift,like the small block chevy going from a 1.5 to a 1.6 ratio something like that would work than again the duration would still be to small.
