Cam change - gains ?Bullet or Hughes

I run the Hughes 5055bl hyd cam in the 505 and it run's well.

TOTALLY!!!!! Tim knows his stuff!!!

Years ago, Engle were grinding cams for Hughes, so the Hughes range were a combination of the Engle lobes. There really aren't alot of companies that actually design the lobes themselves, they're just grinding other people's work.

Bullet's stuff is of good quality and service, you could also try Mike Jones @ http://www.jonescams.com/2006catalog_001.htm

A Comp Cam spec'd out by Brian at IMM in California or Dwayne Porter at Porter Racing Heads in Vermont would also be worth looking at.

Speaking of Engle, their stuff is worth looking into as well. I'm running one of their new KV-3 grind solids, which gives you .573 lift with a streetable 252* on 109*.

Although I don't have my combo dialed in just yet, I don't think the cam is holding me back!

thanks for all replys again.
just got a reply from Kirk @Bullet
recommends their CRB304/312-H8
247/255@050 530/551 lift
this is around what i thought i may need.probly still use the current springs if still ok and won't have as much worry re clearances.block was decked and heads cut to get 78/9 cc
as to going solid?with the rev range i use,traps at 6-6100RPM i don't know if there is a benefit to be had.
this is a just a future proofing plan at this stage.

Tex I saw you are running the hooker comps with the 1 7/8 pri which is decent but they have the 3" collector which is barely big enough for a decent 350. With that size a cam you probably would drop .15-.20 by cutting off the 3" behind the cloverleaf and welding on a 3 1/2" collector. It's a cheap (maybe 125 vs 400-up for a decent set of 2" pri's)and easy upgrade with a bandsaw and any sort of decent welding skills. What you got is obviously working well, I just think from my experience you're likely leaving at least an extra 30+ lb/ft available up to 500rpm higher on the table and maybe 25-30 hp up top all else being equal.

The collector is limiting the peak torque RPM which in turn lowers your HP trajectory from that RPM up. I like the comps just not the collector.

that and the new cam you might have a legit 10 second flat tap juicer!!

What lobe spread and ICL did bullet recommend?

with the corked exhaust wider is generally better along with not a lot more exhaust duration (extra duration with a smallish exhaust port works best when it's got some place unrestricted to go or it'll be rpm limited)...I think he might be thinking you had a 3 1/2 collector?

Wize,
thanks for your thoughts.
Problem with going 3 1/2 inch on collector is i have a 3" system,my class is mandated an exhaust with mufflers with noise limits.
i guess i could go to 3 1/2 for the system,it ends in front of the diff
welding i can do no worries in my shop
Bullets lobe sep is 108
intake centreline is 104

Topbrent,
thanks for your ideas/feedback.
would you be looking at dual or a beehive style spring?
i know Hughes only spec a single spring with damper for their cam
if going solid what size should i look at?
maybe a little more duration,255-260, with a round 570-580 gross.allowing for losses due to lash.
i was trying to avoid solid cos i'm lazy.i don't really want to pull the heads and i am unsure whether the stealths will take a dual spring with out machining
