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.

Blair doesn't post on here much anymore, for some reason.  Plus, I think any EMC cam would be too aggressive for my street engine.

thanks,

Don’t disrupt Blair right now. He’s helping me twist my Fairlane in half.  :)

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 am not sure what to think about that one.  VERY gentle lobes, even though I said that is one of things I want.  I do want to take advantage of the roller lifter to gain some area under the curve.  That one may be too gentle.  I am not sure.  Then, so much duration @ 0.050".  I dunno.  Just thinking.

thanks,

Give him a call. He's VERY easy to talk to, and when I called him, recently, about doing a EMC port job, he took a long time talking to me and wasn't in any hurry to end the conversion until, someone came in he needed to talk to.

It seems like his EMC cam was pretty mild, I thought for what he got out of it. I think it was a HRC with solid lifters?

What is "mild"?  It doesn't necessarily mean easy on the valvetrain.  It could mean that, or it could mean low duration.  It could mean anything.  I am not looking for a hydraulic roller anyway.  What is a good 600 hp pump gas street solid roller?

thanks,

I ran a Comp 308R on the street for a while before I built my blown motor. My Mustang ran high 10's with it and had no troubles driving in traffic or highway. I was running a 454 incher with ported Edelbrock heads.
I didn't run super high spring pressure, 200 seat and a little over 500 open. It pulled to 6500 fine.
The K-Motion 1100 spring works well with the 308R. I ran the regular Comp non-oiling roller lifter. The Comp roller lifters now have pin oiling and are a lot cheaper than the Crower hippo lifters...but I'm sure the Crower lifter is an outstanding piece.

My advise if you're going to run a solid roller on the street. Keep an eye on the springs. When they "go away" things bust. New springs every winter, new lifters every third year.

BTW, the 308R is .675 gross lift, 260@.050 duration on 110 lobe separation. A very old school mild ramp roller that's easy on parts.

Thanks Tommy!

I have Morel bushed lifters, but I still don't want a lot of spring pressure.  I am thinking of using spring pressures similar to what you mentioned.  I know it won't be a no maintenance beast, but a relatively low maintenance beast would be nice.   I expect to give up 20-30+ hp compared to a more modern aggressive lobe.  I'd still like to breach 600 hp.  I figure a less aggressive lobe will hurt more in the low-mid range rpm, but also some at high rpm.  I am not sure about that, but that is what I think.

Thanks,

plovett,

 It actually made 605hp588tq.  600hp @ 6400 rpms and 605@6900 rpms  Peak tq @4700 rpms.

If this won't work give Brent a call and he can spec you something out.

I have another SR cam but it's a tad more radical  ;D

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.

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,

pl

Barry did the details of the cam.  Runs on pump 91 all day, went 11.41 with full exhaust and street tires.  Pulled 15mpg on a road trip (with the benefit of a TKO O/D)

Maybe consider Blairs baby solid roller. My 416ci motor made 600hp with it. With the rocker I was using it only had .525 intake lift and .500 exhaust lift. duration is something like 265/270 @.050. My open spring pressure is 550lbs. It is a tight lash cam and would be streetable in a larger ci motor. Jim

Thanks David and Brent.  Do you know how much spring pressure you are using with that one, David? 

I don't think I will ever get 15 mpg with my C6.  :)

That sounds like an interesting cam.  I think it is a little big for my combination.  Plus, I am guessing Brent spec'd it specifically for the Tunnel Port heads.  I think they flow great, but taper off at higher lifts?   Super cool heads, but different flow characteristics than a typical "medium riser" type FE head. 

thanks,

Was that for a specific class or something?  No way would I run that low of a lift unless I had to.  Sounds like it made some power, though.  Interesting.
