yeah. Was going there was a magical solution, but kinda knew that’s where things were headed. Might be a good time to figure out what I want out of the motor (besides just to run!). I suspect it has more cam than the heads can use. It has a set of 452 heads that had about $1500 of work done on...

I agree, 11.5:1 with quench and a large cam with correct tuning can work with high octane pump gas. with the higher RPM, I would want stronger aftermarket rods with the larger diameter ARP 7/16" rod bolts and light weight pistons. I haven't looked at the 270 head spring choices, if they are like...

Thanks for the feedback. I'll let her know that they aren't very desirable. Her husband passed away and she is just trying to get rid of the last few things.

What changes for a hyd roller cam with 440 Source heads (other than hyd roller springs)? You say you would like to stay away from the needle bearing roller rockers. What's wrong with the 440 Source stainless, bushed roller rockers? I think they look great. (And the price is wonderful.) You only...

Wait for speedmasters black friday sale, and buy a pair of cnc heads bare, and go from there. $1400 budget for sbm heads is pretty small. You could get decent sbc heads for that price. Sidewinder or 440 source would be alternates. If you REALLY want it to run like it should...... save your...

Some goodies arrived from 440 Source this week. Pair of Stealth heads. I added the competition valve job along with the 10 degree locks and retainers. Stainless roller rockers, balancer, and aluminum water pump.

Guys what is your go to Valve Cover gasket on a bigblock engine. Mind you I run stock valve covers but on 440 source aluminum heads. I always use FelPro 1612 thick gaskets and a product that is really good for aluminum (Yama-Bond) or equivalent. I was having good luck but not everytime...

Just messing with you. I really don’t have any recommendations, but for something different I would look at 440 source first. I have had good luck with them for other parts and they are a very good company to deal with. I never heard of them until I joined this forum, and I gotta say they...

Interestingly the cylinder heads don't match. One is 2843906 and the other is 2843908. I'm not sure what the difference is but they are probably going to the scrap heap. From what I see on the internet the resale value is minimal at best. Still waiting on comments concerning aluminum heads...

I like a fast revving engine and I plan on running exhaust manifolds so anything larger would have been a waste. Basic plan is about 10-1 compression with 440 Source heads, roller rockers, solid roller cam, we have not chose the cam yet. DP4B intake, AVS2 800 carb, TTI 2-1/2 full exhaust.

The Edelbrock heads don't pose any issues for me in my '70 Charger. I have a buddy with a 69 Coronet and he has the Stealth heads from 440 source. His clearance is similar to mine. The Stealth heads flow better than the iron heads and they are designed to look very similar. Both sets utilize...

Not to get off on a tangent, but you said it pinged at 30 but normal total timing is 36? Just curious.

...88-90 cc's, not the 75 or so that Mopar says they are (they lied). Clean the mouse turds out of the 906s, and get a estimate to freshen them up/valve job. I'm betting the 440 source heads will start looking pretty good. There are other inexpensive aluminum heads too, sidewinder come to mind.

I decided to upgrade the drivetrain on my 1968 Dodge Charger. Out goes the tired 383 engine with the leaky 727 automatic transmission. In goes a 440 c.i. motor that's .030 over with new pistons and and a top end kit that should produce about 425 hp. Behind that goes a TCI Streetfighter...

I don’t really have a question here but just posting for the group info. When building my sons car a few years ago the one thing I really did not put a bunch of research into was the starter, because I did not think I needed too. I was getting a bunch of parts from 440 Source and just went...

Were the JE pistons custom, and if they were, how much did they run you and did you order any trick deals with em, or just pretty standard pistons? Also did you use a roller or flat tappet cam?

You need to check everything on the new heads as well. I bought new Stealth heads and the chrome was flaking off one of the valve stems. It never would have been seen if the heads hadn't been taken apart. 440 Source sent a me a new valve free of charge. The only way you will know exactly...

It should be ok. They can be removed by having bronze guides installed. The cut all that old guide out usually and press in the new bronze guides. How loose are the valves in the guides? A new set of trick flows or 440 source heads would solve the problem permanently.

The Fel-Pro 1009 fits the bore okay at 4.350, but just barely clears the combustion chamber without overhang with my 440 Source heads. The 8519 are sized for a larger 4.505 bore and are half the price of the 1009.

Heads up! Looked at the new products listed on the 440 source website and bought the (new to me) thicker .083" 6 quart oil pan =7quarts with filter. Anyone else buy one? Or is this oil pan old news ?
