Starting to think about my 440 build, going to start this winter. Anyone have experience with Howard Cams?. It's not a wild build, I'm looking at one of their hydraulic roller cam and lifter sets. A little more spendy than normal stuff but I like the efficiency/extra power of the roller set up. Anyone use them?
Oh yeah, it's a hybrid.....it burns gas and tires!

Also the relief of not having to break in a cam or to swap lifters from one cam to the next without worry is substantial. ^ that^

I'm one of the flat tappet guys but it's not worth arguing about if I'm not building it...lol.
Howards is good stuff. But if it were me I'd use their lifters and a different cam manufacturer. Just personal preference on the cam but Howards makes a damn fine hydraulic roller lifter. If you're going to run one - good choice on the lifters.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Weird. First impressions are a lifter bore issue. I can't see an MP grind eating 9 lobes unless there's a wear or angle issue with the block itself.

I dunno. I lost 2 hydraulic cams this year. One was a comp cams under .500 lift 23 runs and 300 street miles and one MP mild cam that came in the 383 I bought some years ago. Basically street miles (no idea how many but I am sure not too much). I had been running Valvoline racing oil but will try something else. I am giving Com Cams another try in 2 applications (383 street engines).
67 Coronet 500 9.610 @ 139.20 mph
67 Coronet 500 (street car) 14.82 @ 94 mph
69 GTX (clone) - build in progress......

Curious - which ones (as in cylinder/position) went bad?

Double springs?
Pressure over the nose?
EDM lifters?

EDM lifters? Single springs. Not sure, I'd have to look at paperwork but they were used successfully in the previous 440 with an MP .484 Hydraulic camwith no issues.. Not EDM lifters. Just solid flat tappet Comps.

Funny as I have never run a roller and I have never wiped a cam lobe on any of my flat tappet cams. The present eng in my 63 I built and installed in my 63 in June 2011. I use EDM lifters and took the inner springs out for cam break in. Its a custom grind from Dwayne Porter thats .585 & .592 lift with 264 & 270 @ .050 and it has a 110 LSA. I have it in my eng on a 106 ICL and the cam was Nitrided. I use and have always used Valvoline VR-1 racing oil and I added a bottle of Zinc additive. My 493 is still going strong after 4 years and many street miles and a few passes down the 1/4 mile. Ron

Thanks for the reply's, sounds like a descent outfit. Mines a pretty stock build, balanced rotating assembly, a little clean up got it to .40 over, eddy 84cc heads and eventually a six pack all going into a 3800lb B body four speed street car. So far I'm leaning towards one of the Rattler cam and lifter kits CL728045-09, says it's 235/243 @.050", .530 lift on 109LSA designed for 2000-5600 rpm.
Oh yeah, it's a hybrid.....it burns gas and tires!

for a regular cam do all of the caveats: correct spring psi for breakin. zinc oil. proper prep so it stats INSTANTLY. conservative timing for breakin. Hughes lifter OD clearance precheck "the thunk test". thermostat OUT. load the eng (I hear a dyno is the best??). cooling fan in front of rad. mixture not too rich. read "breakin secrets" at www.mototuneusa.com which is more for rings but applies to cams also. front of car jacked up (helps with air pockets) & gives room underneath to spot any leaks/issues. ANY issue dont think about it just shut it off now/fix it/then restart & continue on on the breakin time. you in dr seat to goose the throttle and shout orders! several helpers, one to set dist to total (36). another guy to add trans fluid another guy to check for leaks. You have thousands of $$$ & alot of time in this & you have ONE shot to get an excellent breakin as opposed to a mediocre breakin that has lower leakdown numbers & wears out sooner on down the line years from now. You have ONE shot!

They spec'd me a .480 lift, 280 adv. duration for my 505" stroker with ported heads!  When I asked if they were sure about this recommendation they said "Yep!".

I agree as why would anyone spec a cam like that for a 505 stroker ??   Heck I had more cam then that in my stock 383 with pocket ported 452 heads. Ron
