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...

Ok so overall the kits from 440 have been pretty decent and reliable?

Just finished the dyno session on saturday before Christmas on the street motor for my 63 and could not be happier. 440 short block, 9.8 comp. KB pistons, 452 heads topped off with Rick Allison's A&A cross ram. Made an EVIL 666 HP and 603 TQ on pump gas from Shell. The kicker is it made 500 ft...

In another thread, I’ve asked for and received help on my car which turns out had a lifter failure. In this one I’m going to solicit some advice about changes I might make when it goes back together. The car itself has great pieces- TCI 727, 3500 stall and Dana 60 with 3.91 gears, all of which...

I googled them too, they have a .010 shorter C/H and a 4cc larger valve relief than the equivalent Icon.. So according to Mahle his numbers are good and 440 source shows the Icon about .3 higher... I'm thinking without taking measurements myself he's pretty close... Personally I choose the...

Just using a factory cast iron 440 block. The idiot who built the car put 440-218 step headers on using 440 Source heads where on TTIs website it specifically says which heads work with the 218s and 440 Source is not one of them.

A friend convinced me to at least partially assemble my rough 67 GTX while still working on trying to do a decent job on my 68 Coronet. The thinking is if I can get the GTX to at least run and move under its own power it will be easier to sell if/when the time comes. The plus side is we can...

The motor has 440 Source heads. You think this could be part of the problem? I have TTI headers but they need cleaning and Im trying to get away from headers.

...about doing anything to mine. I had thought about boring or stroking this engine but I believe a .030" bore will suffice. I am leaning towards a set of 440 source heads to keep the stock appearance, same with an intake if it will all fit under the hood with the factory style air cleaner I have.

Might try 6’s, what do you look for on plug that relates to heat range?

something was wrong with that carb or the floats were off or too much fuel pressure. if speedbird didn't get down to the problem he would have said the carb was junk but it was user error not the carb. am running 2 800 avs2 one on a 440 RT small cam stock exhaust 3.23 gears and on a 4400 lb with...

...again and am seeking advice on how to achieve what I seek. Funny that a Hot 440 is mentioned because I have a 440 in the shop. The 440 source heads were for that build. I was going to give that motor to my buddy who owns the shop for his 67 Dart. All I want to do is get my car back in the...

I'll round up a 26mm for the future. But the thing is, I bought the plugs from 440 Source specifically for their Stealth heads.

...on the deck below each cylinder situated between the head bolts, none of my other blocks had these, is it one year only thing?, 440 source heads are at machine shop so I don’t know if it has corresponding holes, pics on their website don’t show any. I don’t think they are necessary because so...
