Going out on a limb I would think no way on those lifts w your deck dimentions. I'd flycut the reliefs deeper & hughes sells a cutter shaped like a valve for this. I'm assuming your shortblock is together  . You would want the piston deck to be at least .150" thick after deepening and it would change your balance slightly.

I ran a 296 degree 557 lift Purpleshaft cam in a 440 with 906 heads and TRW 6-pack pistons...twenty years ago! As I recall, I put one head on the block w/o a head gasket and some clay on the piston, set the valves in that cylinder to spec and rolled it over. It must have cleared with room to spare, because the engine ran great and the car was very consistent.

You could mock it up w a pair of light springs and a dial indicator & w the piston @TDC move the valve down .557 (or .509) plus .080 addt'l on the intake valve & .100" on the ex valve & if no contact then in use with the piston/valve phasing it could never be any tighter than that. Might be something to check before you purchase a cam.

If you're all assembled you could take off a pair of springs w an on engine valve spring compressor & put on the light springs & experiment a bit. iirc one of the cam companies once you had that dimention in hand had a spec sheet listed that would tell you which one(s) of their cams would clear and you could probably cross that over to our MP cams

I'm sorry. I didn't know that having dual springs on the head already would affect piston to valve clearance. Maybe you could explain it to me. And if you bothered to read my first post, you would see that I acknowledged that I need to check the clearance. I just wanted to know what I probably could run. Hence, I wouldn't buy something too big that would not have any chance to work. So I'm asking "whoevers" to get a feel of what will work. I will then get a cam that will likely work. Then I will check the clearance. I never asked what cam I could run with stock springs. I know to match the springs with the cam (but thanks MoparforLife for pointing that out - no sarcasm intended at all). So kudos to you MoPowered_SS for raising a red herring.. whatev (wags head in circle and gives the "talk to the hand"). Quote:

Subject: Highest lift cam on a stock 440?
nowhere in post #5597643 said your using double springs.
think about the subject before putting fingers to keys. thank you.

I'm sure they will hit if you do this test. Peak valve lift is not at TDC, but occurs at about 106-112 degrees of crank rotation. The piston is a mile down the hole by then. You can test with a dial indicator, but not like this. A clay test would be the simplest.

I agree with the coil bind & retainer to guide factor. Over .500 lift I would be sure to check this, with stock valves.

I ran first the 292 .509 then the 320 .533 with flat tops .030 in the hole with no valve reliefs with the dual springs with no problems! Had about .045 off the 906 heads too! Did a crude check on the 533 it was tighter .060 to .070 but never hit and I drove the crap out of it shifting as high as 6600 but best quarters were at 5800 to 6000 Now on a hydraulic I use solid Lifters and adjustable pushrods?? to check Checking is always best? But back in the day

I was looking here - http://victorylibrary.com/mopar/mpcam-tech-c.htmAnd it says that the 509 should be installed at 108 per Chrysler. Quote:
Big thing with the 509 is to make sure it is degreed at 107 they are dogs at 103 fun wow!!!
I two like RPM performer 750 holley, headers and 3000 if you don't degree the cam 4000??

Man, I guess SS was right. I should have posted more info. My car is a 4 speed/4.56 rear. Gonna have headers. I'd run a 557 if it won't play Chuck Woolery and make a Love Connection between my pistons and valves. Six Pack or Performer RPM.

528 solid would probably work well. The 557 and 509 will require a good stall (3000+) and 3.91's or better.
Also if you want to run the 509, be sure you have headers, a good dual plane intake, 750DP, along with the stall and gears, otherwise it's going to be a DOG out of the hole. TRUST me on that.
Why not try a newer cam grind? Straightline makes some good cams. I think the 6 pack pistons should be ok w/ a 557. after you subtract the lash you're about 537 or so.

Well that is wrong the suggest 106 got a mopar book right in my hand and every mopar book I've had in the last 26 years says 106.
Now in that 25 years I had one for 8 or so years and help 3 or more friends with them and I can tell you they love 103 intake installed centerline.
Now on a 4 speed (or a 4200 stall) 12.5 to 1 compression fully ported heads with 4.56 gears maybe 106
I swear some of you guys have never ran a car tried a different degree and tried it again!!!

accurate infomation yeilds accurate responses and with that said...results will vary from engine to engine I have seen engines with less do more with accurate dial in from under the shade tree

Straightline no longer exists and he does spec a good cam ( I have a roller of his on the shelf) but they are someone elses grind??
Since everyone has a cam almost exactly the specs
of the 509 lift duration and LSA so buying from Comp cams or other makes it a new cam. these cams make serious power that's why they are copied.
Now for the guys that need/want less performance and some of the issues that come with them there are Summit brand cams!!!
There is probably something to the longer exhaust duration verses the intake but most still sell the even split and many builders perfer them so it is Tomato Tomato???
I talked to Scott the other day. I will be buying one of his cams soon. 236 (@.050) 550 solid. If you want his # PM me. Also the Summit 488 cam is pretty good. Got it to run 12.90 in a mild 9:1 440 in a 3900 lb B-body.
