My bet is the answer lies here. Dry threads. The torque wrench would show the correct reading. But the fastener wasn't stretched far enough due to the friction of dry thtreads. If the head and block are flat and undamaged? A new gasket (I like the Fel Pro 8519 idea in this apllication) and...

Didn't you give the shop a piston to work with and the specs before they machined it ??

On my 440 source heads the cover rail casting is not located in the right place, in the corner its off a little so you only get the edge of the gasket touching the head. you need to glue the gasket in place and let it set up before putting the cover on. use whatever silicone you like. but you...

For a "mild street pump gas engine", I'd use the stealths, or put .120 cometics under the b1/bs. (Maybe .090s . Whatever it takes to get it to low 10 cr)

It’s definitely not that simple where a certain DCR will work in all scenarios. Gear ratio and converter will greatly affect engine load. You have to look at each combo individually. Why would you go away from the TF240 heads? Just looking for something with a larger chamber to lower the static...

I have TF top end with TF HR cam and Howards lifters 91767 on a new 440 build. I recently had multiple emails back and forth with a tech person at Howards. He said those Howards / Morel lifter must be at 380lbs open no more no less (design limit for that lifter). That is what they can take and...

So you are not using raised port heads on a 1969 B Body Coronet in combination with the 440-218 TTIs? As per the TTI website the 440-218s are not designed to be compatible with 440 Source Stealth heads which are on my factory 440 block. Do you have a part number of this Summit mini starter so...

I did not, I have Trick flow 240 heads on mine, not sure if that makes a difference compared to 440Source heads or not.

For sale is my 1970 Super Bee. One of 599 440 six pack 4 speed hardtops made. It’s a pretty basic bare bones muscle Mopar, with manual steering and brakes. Just buckets, tic toc tach, AM radio and the hi impact FC7 Plum Crazy paint are the only options that the original owner ordered in late...

I was thinking decking it atleast. 050 but my engine builder thinks that's too much. He says 15 on one side and 20 on the other. I guess I need to CC the 440 source heads and go from there.

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

Hi all. I have done a bunch of reading in the million threads and think I have a general idea of what I want to do based on my budget, but figure some input from folks with experience would be good before diving in. My 440 is fully disassembled and has been inspected, it appears serviceable...

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?

That's my question. See posts #13 & 15. Unbolt headers from heads. I don't recall ever doing this job pulling with headers attached, and that's going back 50 years. Anyway, you're a youngster ! Just don't kneel on magnets, or you'll never get up.

I use the NGK plugs also. I would start at heat range 6 and then check the plugs to see if they should be hotter (5) or colder (7) I opt for the slightly shorter ISO plug length 1.98" (BK) vs the JIS 2.086" (BC). Gives a bit more clearance on cylinder #4 to inner fender on my 440 block with...

The 4.25" stroker kits (505" @ 4.350" overbore, or 512" @ 4.375" bore) are pretty easy to build. The crank pins are 2.20" GM size, so the rod big ends usually clear the bores without needing to be notched. I haven't bought a Stroker kit from Hughes, so I can't comment on that. Got CNC heads...

Hi, I wanted to introduce myself. My name is Roy, and all the info that you guys post has really helped me on several parts of my rebuild. I have a 68 charger RT, 440 automatic. Just finished the second rebuild on the engine. I went with a 512 stroker kit from “440 source” and their aluminum...

I'd port the aluminum heads before spending $ on a compression increase. Power per dollar will be better. For what it's worth. I have a 73 Challenger that was built for my wife. 360, ported factory heads, LD340 dual plane, 650 Holley, 220/230 cam, headers, true 9.0-1, 3.55 gear. Runs on 87...
