Search results for query: 440 source heads

Hi guys I've decided to spend a bit of money on this dust collector I have in the shed (69 Coronet-440 6 pack). So I'm starting with the engine as it needs a full rebuild and I like either 440 source or Hughes stroker kits. I'm leaning more towards 440 source due to a lot of positive feedback...

I just got a set of the stealth heads from 440 Source. Do the factory pushrods work with these heads. And will i need to open the pushrod bore as I have the 3/8 pushrods. It's a stock 440+6.

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

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...

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

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...

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.

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...

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.

For a street motor without power adders, the KB 236 or 237 are good choices. I have the 237's in my 440, with Source heads are about 10.3:1. The 236 has a raised pad for open chamber heads. Just looked at Summit, ICON forged are about the same price as the KB's. I'm not sure on weight difference.

Yes I'm using those headers with Indy Cyl Head raised port heads on the 63 and no problems SUM 820441 Summit brand starter

440 Source heads would be the best bang for the buck.

I used Ohio Crankshaft's kit (probably before 440 Source was around) with no regrets. Use the smallest overbore you can, it makes for stronger cylinder walls/better ring seal. RPM heads. Complete Hughes valvetrain (solid) and my 6 Pack induction. 10.6:1 CR, Dougs headers with 3" exhaust-X-pipe...

You misunderstood. I have non raised port heads (Source 440 Stealth) and 2 1/8 440-218 TTI step headers and am sure this mismatch is contributing if not the entire reason I am having header/starter clearance problems.

You said you wanted a little more cam. Ok the old Mopar P4120235 or P5007697 (or something like that) would be good. That is a stock Street Hemi grind. .484" lift 241 duration. Simple, friendly and easy. If your heads need anything to speak of, and they probably will, I would buy new stealth...

They have no super stealth heads in stock. These heads have been discontinued.

Be aware that they suggest re- torquing the heads if you use their head gaskets. Also, I didn’t like their 440 valley pan.

...mid 230's low 240's max for low rpm you're looking for. For lift with those heads, you might as well not go lower than .500 (imho). 440 Source heads flow well, so use them. Then it's about LOA and centerline... May want to lean more toward the 110 LOA and 106 CL numbers. An example could be...

At that point, maybe you should consider a stroker kit from 440 Source?

Headers? what cam did you use? what is your engine vacuum at idle?
