I had a 383 built with 440 Source aluminum heads, I like it a-lot. Especially with the tunnel ram.

I am in the process of negotiating on a 72 charger. The car is a bit of a Frankenstein, at the same time it has a lot of potential. The car currently comes with a 400 / 727 combo with 3.91 diffy. The goal is to make 425 hp/500 tq on pump gas. I also want to run a therm-quad as well as HP...

@Auggie56 on the old smogger '78 if you want to bump the compression up a little, and want to use iron heads, grab a set of "516" castings or "915" castings, they are the early closed chamber heads. Year wise, you'd find "516" on something like a '66 383, "915" were '67. If you want aluminum...

Strip it down to the shortblock and find a good machine shop. I see rust in the bores so it likely needs to be bored .020 over at a minimum. You can bring them the heads and they can recommend options for rebuilding / replacing. Aluminum heads are a good option: 440 source Stealth, Edelbrock...

Well, how do you think about 440s since I just got one haha A couple of things though, unless you had domed pistons or decked block and heads a lot, you didnt have 10 to 1 you had low 9 to 1s from what I researched. Also ive heard that there's wild variations in the quality of castings...

With your pistons that far in the hole, you need a steel shim head gaskets and some serious head work. You can't mill it to far as things begin to not fit without other machine work. The 383 4bbl 325 hp engine I recently built went back standard bore with all original pistons that were 16...

They have that logo on the runner and the chambers look the same.

That was part of my confusion on the valve gear. They recommend Harland Sharp, adding 1k to the mix. Are there other, options that would work? As we all know, our Mopars creep up on the expenses quickly. I do appreciate your input.

Stock 1.5 rockers at this time

I had a 440 based 496 that used a 440 source kit. I used a 6bbl intake, hydraulic roller cam and eddy aluminum heads. It has been a few years since the build and I don't own the car any more, so I don't have the cam specs or recall which heads were used. It was a blast to drive. Below is the...

...I am strongly considering going with a set of 440 Source “Stealth” aluminum heads and possibly their aluminum dual plane intake. The 440 Source heads are spec’ed at 80cc so the CR would stay about the same unless I make other changes like milling the heads or block, changing pistons or some...

I was going through my garage and I have some parts I purchased back in 2018 with plans to hop up my old 440, what I am wondering is if this cam amd rocker assembly is to aggressive for a street car and more set up for a street strip leaning towards strip setup i would like to get more power...

Hello everyone !!! maybe someone had the same problem like me …. We rebuild my 440cui RB-Block and stroke them to 512 cui with 440 source kit . after we using brand new 240 Trickflow heads for the upper part, and because I want change my ignition from revanator system to the MSD system I try...

If you are buying new heads, you don't need new seals, or locks. I use 7* locks on mild hydraulic roller set ups all the time. Also, I would doubt new retainers are required, as a mild hydraulic roller really doesn't need a crap load of spring. It would all depend on which spring you go with...

Tried the Powermaster 9523 however wouldn't fit and can't find any mini starter besides the RobbMc that will work and even then you have to make adjustments to the header tubes for clearance.

I have a 69 440, stock bottom end with 440 source aluminum heads, lunati 703 voodoo cam, headers, factory electronic ignition, edelbrock performer intake, and edelbrock 800 cfm avs2. 3.55 gears and an od 4 speed. The car is fantastic, It’ll cruise highways without breaking a sweat and get 15 +...

Open to help here. 400/512 stroker. Herbert hyd roller cam, 485/500 1.5 lift. 64 Sport Fury convt, 4 speed. I've been looking into heads. I would go 440 source, but by the time you make all of the changes for roller cam, you might as well go Trick Flow. I had bought proform roller rocker setup a...

Get as crazy as you want with a different block and heads. You could redo yours with an upgraded cam and some ported 440 source heads painted to look stock also. Your car and your money so do as you wish but I would protect the original block and heads if it were mine.

I think you’ll be in trouble. Give the cam type and specs.
