Cam for 440 street build

[TrackPack]

I'm looking for input on a cam for a upcoming 440 project. It will be a pump gas friendly build for a street driven road runner with a 727 and 3000 stall converter. Have not decided on a rear gear, but most likely 4.10 or 3.55

I originally bought this 440 with a spun #5 rod bearing, but it was a low mileage .030 over cast piston rebuild. I plan to use as many of my big block parts that are just collecting dust.

Specifics:
67 440 block .030 - cylinders show little to no wear.
Replacement crank from early 60's 413.
Stock LY rods with replacements for #5 and #6
Cast Badger flat top pistons measured .086 below deck

Options:
915 heads pocket ported with 2.08/1.74 or Edelbrock E-street 84 cc
Stock cast iron intake or vintage Edelbrock TM7 Torker.
Stock HP manifolds or 2" Hooker headers.
Crane ductile iron 1.6 rocker arms or 64 Max Wedge 1.5 rocker arms.

The compression with the iron heads comes out to about 9.25:1 with steel shim gaskets. I prefer to go with a mechanical flat tappet cam and have found two that I think might work.
Comp Xtreme Energy 23-230-4
230/236 @.050 and 488/501 110

Comp Xtreme Energy 23-231-4
236/242 @.050 and 502/511 110

Thanks for any input. I'm not finding too many mechanical flat tappet cams in this low lift and duration range by any manufacturer.

[1] Get a custom ground solid flat tappet from Comp Cams. I am getting one done now, $388. They have dedicated Mopar lobes that have more lift & area under the curve than Chebby & Ferd lobes.
[2] Be aware that the crank flange prior to 1962 will not accept a 727.

Question - what are you going to use for lifters?

I'm up for something custom ground, but would like some input on specs before I contact anyone.

This 413 crank is identical to the 440, so I'm thinking it's 63 or 64.

The later cranks that work with the 727 have threaded holes in the flange; the earlier ones have plain holes, drilled through.

Lifters. I wouldn't use anything made after 1995. Solids would be real hard to find. I get pre-95 OEM lifters from a junk engine & have them re-faced. I modify the stock hyd lifter for sol use by making a s/steel spacer to go under the piston. Real easy with the 440 because it does not have p'rod oiling.
Comparing hyd & sol cams. You have to take into account the lash of the sol. So, with the large 0.032" lash that the MP cams had, you would subtract about 15* from the 050 number to get a rough equivalent to a hyd lobe. Eg, Mopar 284/284 sol is about 241 @ 050; about the same as a 226@050 hyd lobe. Tight 0.018", you take off about 8*.

Looking at the specs provided, I would use these dedicated Mopar lobes from Comp, with headers.

Singlep attern cam, MM lobes.
Lobe#6582. 269* adv, 243@050. Valve lift is 0.549" with 1.5 rockers
108 LSA

If you have the e street use them

Stock cast iron intake or vintage Edelbrock TM7 Torker.

Torker or TM7 (two different intakes iirc but wither beats a stock cast iron to death)

Stock HP manifolds or 2" Hooker headers.

HP manifolds unfortunately. Maybe 2" headers if you run 4.10's

Crane ductile iron 1.6 rocker arms or 64 Max Wedge 1.5 rocker arms.

Those are hyd flat tappet,no?

I think you're getting the cart before the horse, so to say. You contact the cam maker and give them the info for gear and TC, tire size, etc and then they can match it to a cam profile.

To be honest, I'd rather gather some opinions before I contact anyone. I figure it can't hurt to gather some info beforehand.

Thanks. Only hesitation with the E Street is that a composition gasket is needed, so compression drops to about 8.95

Why not sell the heads you have and buy the 75cc E-Streets?

I could try to sell them I suppose, but shipping usually kills deals like this. Not sure how desirable the straight plug head with powdered metal seats are these days. The 915's are ready to bolt on, just need valve springs.

Just throwing this out there - but has anyone successfully used a low lift hydraulic roller cam with solid roller lifters on a combo like mine? I had ruled it out because of expense, but flat tappet lifters seem to be a real problem these days.
