A hughes whip lash cam should work real nice and yes I would use the 516 heads if I had them sitting around ready to go. A lunati Voo-Doo or comp XE cam would be good also. Something in about the 220@.050 lift range would be about right. Those heads don't flow great so getting the valves open as fast as possible should help get it flowing at it's peak sooner and longer.

For sure stay at 224* @ 050 or lower on the intake side. While everyone wants a nice lope, lope = overlap = compression bleed off = bad for a low comp smogger 440. See here for some inspiration: https://board.moparts.org/ubbthreads/show...&PHPSESSID=With only a 3.23 gear you don't want to go overboard with duration, probably not more than 220, with a 3.55 you could go up to around 224. You can run a bigger cam but then a quality built torq converter built to flash to 4000+ like a PTC or Dynamic is a MUST.

Summit 224 234 465 488 with a 114 lda. Works great and is only about 100 bucks with lifters.

I will go against the flow and say 516s. If you install the bigger valves they flow almost the same as a 906 and you also get more compression and if you get flat top pistons at zero deck you can get some quench that helps HP TQ and MPG.
Over lap does not affect cylinder preasure as much as the late intake closeing point on a long duration cam but it will make it lope more at idle. The whiplash cams are desighned with tight overlap angles or LSA to make them lope and short duration to get the intake valve closed sooner and build cylinder preasure with low compression, they have very fast rates of lift to open the valve faster to the peak flow area of the valve lift.

for a cam, I'd look at a lunati voodoo 60302 or 60303.
heads, 906 will flow better, 516's will help compression. I'd use whichever ones are in better shape.

I got the Larger of the summit cam and lifer set. the 224/234-465/488 duration. This will be ran with 516 heads. I have a 3.55 suregrip 3rd member ready to go in.
I also got the standard SP ring set,main bearings,rod bearings, and cam bearings. A true roller t chain set,FP gasket set and valley pan,freeze plug set, mr. gasket lightweight advance springs for the distributor and i think thats it!
I have a high volume oil pump, and a stock windage tray that i am going to modifiy for more oil drain back. I'll pick up a fuel pump and water pump from the local auto part store...
As for headers in an e body, i was thinking the regular hooker Comps? I also have a holley 4150 750 that i think will work ok.

if you want nice headers, check out the hedman elite's
PN HED-78038 at summit, $337. they're ceramic coated, 14 gage steel, with 3/8" thick flanges. AFAIK they don't go under the steering linkage either.

I put together my '73 440 with almost the same parts, same cam, same heads. I used the larger (than stock) valves from a set of 346 heads. I gasket matched the intake and headers. I am hoping to start mine up for the first time around the end of Feburary. I cant wait! Keep us updated! Good Luck!

Easy question.
Is the summit cam a 3-bolt or a 1 bolt cam?
I am at work at the site is blocked for some reason.
I am doing essentially the identical build for my Dart Sport.
Thanks, ROB
