I've got a few things to work with now. 69 440 block, 4.150 stroke crank, H-beam rods, 9.5 to 1 JE pistons, 286 casting Max Wedge heads, 64 model Max Wedge crossram intake, AFB carbs, small solid roller ( probably in 250-254 @ .050 range), Max Wedge manifolds, deep pan. I'm excited to build it .....have no experience with a big block. How ya'll think it will run ?

Like a scalded cat!!

480 or so HP

I think that your proposal will be good for a pump gas torque monster that will be RPM limited by the carbs, exhaust manifolds and small cam. The compression ratio will tame it a lot, too. It should be relatively civilized and long lived with a lot of wow factor

Run a solid or if a Hydraulic look at some of the Hughes Grinds that have about .560 lift and ~254/258 ish @.050 duration would be about perfect. The Comp XE that is 251/257 @ .050 is a good one too but I'd look at the comparable Hughes if it were mine. 108 or 110 spread in at around 105 should be perfect.

It'll be a blast to drive, big torque and good power through the mid 5000 range, probably peak power around 5100-5200 but it really won't fall off too badly with the Maxie manifold and the right carb set up. The heads are probably your limiting factor but the manifold has a way of getting more out of them.

I'd look for about 530hp and maybe 565-ish lb/ft pretty much flat from around 2500 to 4800.

Big cubes don't really need a lot of CR (but more will make it Happier/crisper) but it will be a LOt of fun. You could put a smaller cam in it and probably grunt out close to 600 lb/ft but IMO you won't be as happy with the power curve, you almost want enough cam to take a little off the very bottom, after all you don't want it to feel like a 455 oldsmobile

The maxie ram-horn manifolds really don't give away much at all to say a 1 3/4" tube header, and they look really killer under-hood....wish I had a set!!

I'll post dyno results after we run it but I think it will run a little better than expected.....but, the dyno doesnt lie....lol

Thats almost exactly what I had in mind....based on what I've seen from stuff we've dyno'd.

We built pretty much the same thing for my uncles car, we had more compression though IIRC, and it made 670 HP and I want to say 710 lbs ft ! It was in a gutted 64 Plymouth ran 10.20s all day long ! It went the best of 10.10 in the mine shaft ! Good comb !

didn't Andy do an A&A (allegedly better then the OEM Maxie intake) on his 514 with more compression, Indy EZ's and a larger cam and it made I think 640-ish?

I think you can make 600 lb/ft+ with the right streetable cam but the 600-ish HP might still be a stretch with the low CR and (lower) hydraulic lift cam.

The Hughes cams seem to have among the best rate of lift for duration hydraulics out there, it will help because the Stage III heads tend to stall at low lifts so to make power you typically have to old school "hang em and squeeze it" (long duration & high compression to hang on to the torque well past peak to get the RPM)

Mine wont have a hydraulic cam in it.

My bad, I saw 250-254 and assumed (misread) you were going hyd flat tap

Yeah with a roller you could should see 600hp and and over 620 lb/ft at 493 cubes

Smallish SR you should probably spread the scenters a tad and put it in a little late to help the top end a bit, torque will be massive with a roller, just got to get it to hang on.

Sure you can make a dyno read what you want...but why ? When you do this everyday, the dyno is just another tool in the toolbox. I know there are some hyped up dyno numbers out there but they will always be found out in the end. I know not all dynos are the same but they shouldnt be in left field if folks do things right. The dragstrip is the tell all but that also varies with track conditions, weather , etc. Weve done enough engines and folks know our dyno and our reputation......where I work is Kowalsky Racing Engines. www.kowalskyracing.com I'll post the numbers when its done....thanks for all the input from everyone.

I forgot to state on that M.W. motor all testing was done with headers The first set was a set of hooker 1 7/8 primary pipes with a 3.5 inch collector for the A bodies, the dyno operator made a set of dyno BB Mopar wedge headers that where 2 1/4 primarys, 25 inches long into a 4 inch collectors, I thought they would hurt the motor down low, they picked up the average by around 17 HP and 20 ft. lbs (tested from 3000 to 6500 RPM) All the gains where above 3500 RPM
