600 hp solid roller street cam?
« on: November 13, 2020, 12:42:01 PM »
What's a good 600 hp solid roller street cam?  ~450 cubes, 315-320 cfm heads, just under 11:1 compression, 400+ cfm intake manifold. 2" headers.  "Enough" gear and stall.  7000 or less rpm.  Bushed lifters.

I don't want huge spring pressures, even with bushed lifters.  I will give up some hp for street use and longevity.

thanks,

pl

My humble opinion, there is no cam currently sitting on the shelf for your needs. Have one of the gentleman of this forum get one custom ground to your needs. It could make way more difference than you imagine.

There are plenty of "on the shelf" cams that can make over 600 hp.  Still, a custom grind is almost a given.  There is no downside.  So your point is well taken.  However, I am looking for rough numbers.

I am thinking 250-254 degrees on the intake with .650-.675" gross lift, on a 108 to 110 LSA. ~8 degrees more duration exhaust.  Just a ball park guess. 

Anybody have any combos they could share?

thanks,

Comp has one that’s 262 262 .670 .670. I have one on the shelf but never used it. Pretty sure Jay made 650hp with it in one of his 500” edelbrock headed engines. So I bet it would get you there.

I'm using a Custom Comp 254/260 695 lift 110 LSA solid roller in my street 465.  Barry spec'd it for me a while back when he built the short block.  11:1 CR flat tops, Blairs street pro-ports.  It's a little rowdy, but pulls strong up close to 7K, idles around 1k.

Plovett I have the first solid roller we used when Brent and I were doing a few Tunnel Port builds.  It was 465 cubes and made 600hp
with unported heads.  There is one dyno session on the cam and springs
It's a Bullet custom solid roller Duration @50 Intake 260 Exh 270, Gross lift Intake 616, Exh 660  ICL 104
I also have the springs we used and if I recall they were around 630-640 open pressure.
If it's something you could use send me a pm.

I would suggest calling Blair and getting the cam he used in the '19 EMC. With that, he got 600 hp from less than 400 ci and his heads flow is similar to yours.

I don't know the cam specs of that cam but, I don't think it was much more than .600 on the lift and still in the 240's @ .050 for the intake lobe.

Yes, I think that is close.  I already have a Crane 246/254, .637"/.658" 108LSA cam, but I think it is a little too small for the goal.

That sounds good.  How did you decide on a 110 LSA?  Does it need idle quality?  Just wondering.  What do you think you are making hp wise?  Run okay on high octane pump gas?

thanks,

That looks like it is in the ball park of what I am looking for.

Lift: .656 / .656, Duration @ .050: 249 / 255, Centerline: 104, Rough idle, Pro street/bracket, Good mid-range torque, 11.0:1+ compression & 3500+ stall converter.

I dunno Gary,

That looks pretty dang big for my application.  Do you remember the rpm the peaks occurred at?

thanks,
