You all validated what I suspected. I will sleep better having made the investment to go through these heads completely. Others that believe the OOTB viability of these heads, YMMV.. Agree with the surface finish comment too Moper, the .003 true up cut we made first was primarily to remove this...

That plug is way beyond a couple jet sizes rich. The power valve tipping in early combined with jetting maybe, but it even looks richer than that and so does your mileage. AFs in the 12s generally look black but not sooted Moper is right, your power output on the dyno sheets are way down for...

..but their corporate name couldn't be more unfortunate at the moment

I am hoping a couple of the experts can share their opinions, findings, and experiences with Edelbrock heads. I am in disagreement with one of the volume sellers of the LA Performer RPM heads over what are acceptable "out of the box tolerances" for these and his immediate response was if you...

Looking good here - thanks to Jay and nice story layout by webmaster http://isispower.com/isis-power/1972-demon-wired-with-isis-power/

We are closing in on getting our project completed - 6 years roughly from buying the donor Here it is lately (and you can go back in the thread to see how it looked back when) http://www.forabodiesonly.com/mopar/showthread.php?t=93184&page=3

No motor plate, this is pretty straightforward swap. See: http://www.engine-swaps.com/Pages/ArticlePages/GoBig.html Schumacher mounts are simplest way to go to replace the S6 with a B and are fully sorted out for clearance. Manifolds work but are chokers - I would seriously consider his...

There are no drop in hydraulic roller setups for 340 LA, if for no other reason than there is no standard pushrod length for any of the aftermarket lifter options. A mechanical roller doesn't have the height issue with a simple slug and roller tip. Hughes makes (sells) hydraulic roller lifters...

Like most of the construction materials and consumables in an automobile, wiring has to meet standards and specs. Go with what the OEMs use. GPT is basic PVC auto wire. Cross-linked (GXL, SXL [hi temp]) insulation is best and a very small price premium over GPT. TXL is nice but not a...

We got StreetLynx early in its availability, and as we know there are a lot of variables among A-bodies (all Mopar bodies) through the years, ie Demons are shortys. I understand the RMS caution about trying it, Bill R is pretty conservative. We went with 8.75 because our power output doesn't...

Interesting in every Wilwood package there is a disclaimer about working on braking systems, they are racing brakes (not street?), hire a professional mechanic, etc. Kind of insulting to sell an OE replacement kit, then include these disclaimers? Anyway, there is generally a lot of fitting...

Glad that got resolved for you. btw, valve piston contact isnt necessarily visible. Interference in the thousandths is all it takes to bend a valve enough so it wont seal properly ever again. Depending on the dynamics of the valvetrain at 7000, is the spring keeping up, is there flutter (valve...

Lets see 696 RWHP = ~ 900 Flywheel BHP. We know torque = hp at 5252 rpm, so lets say the power shift at 5000 was 85% of total engine output, thats roughly 780 ft lbs through the 833.. 23 splines are very tough, and work behind some very strong big inch wedges. BTW, looks like the 23 spline...

If you are using H4s pls confirm you are using a relay harness too - ie your headlight or high beam circuit (red & purple) is only sending +12v to energize a relay that is supplying the current to the bulbs? Do not use your stock headlight and dimmer switch to power H4 bulbs - period. In these...

Jerry, what do you suppose caused the pushrods to bend? You said you hit 7K, RPM by itself doesnt bend pushrods. Then the thread turned to chamber volumes(?) You bent pushrods because something collided, most likely a valve to piston. Has your LMS disassembled the heads and measured out your...

That is a super nice job working up bent metal to finished product. The round bar work is sweet.

After the engine and chassis electrical got sorted out, the dash we had been planning for 3 years went together You can see the steering column harmonica connector converted to a Weatherpack for ISIS left turn, right turn, and horn inputs. The column is a "no key" 67 Dart column restored and...

We are kinda nuts around here about Mopar electrical. Probably because for all of Ma Mopar's great engineering, it was probably the least well engineered system on the vehicles, particularly when we are looking at it 50 years after the fact. Actually, its more than 50 years after the fact...

The wheels are Rushforth Design. After we decided on size, offset, and finish; he builds you a custom wheel. Only issue we had is he uses a lot of contract shops ie CNC cutting the centers, hoops, weld, and powder coat which is fine but it is a low volume supply chain and takes time. In a...

These are sweet. FABO find. Worth the hassle to get everything mocked up - aluminum tank filler in 2" tubing, stock filler pipe (cut down), marine 2" ID rigid fuel pipe.

We really put a lot into getting this exhaust to work. Started on it a couple years ago and got stopped by clearance trying to work cutouts into the area forward of the X pipe. Its pretty busy in there on an A body and while anything is possible, it was going to be a time sink. Caused a...

Here is how the arse end came out with the custom tank. We had it fabbed to stock but WITHOUT the spare seat area. This thing by my rough calcs is around 30 gal. Power Tour?

Thanks to all who have appreciated on the progress. Following posts will give a glimpse into more of the finished product. We got slowed down by what can only be described as a demon in the engine build. It is not our first setback, having already had a block that was supposedly fulled checked...

Followers of this thread - thanks for your interest and patience. We will post some more completion pics as we near getting it on the road.

Year one sources all harnesses from vendors - they aren't in the manufacturing business. M&H does most of the Year One harnesses and all the Mopar AFAIK. Their online catalog is excerpted from Year One catalog pages. Evans is a Mopar only wiring vendor, but doesn't do dash harnesses. As dash...

in Champion RN12YC for pump gas and street driving, hot enough to stay clean but not pre-ignite decent gas like posters above state, in stock high compression 340 you cant go wrong with Autolite 65 (or 64 for strip/track extended high RPM, minimal part throttle/idle)

Complete TKO600 EXtreme 5 speed set up by American Powertrain (aka ProFromance, aka Driven Man), 650 ft lb + rated, blueprinted transmission. No abuse, 300 road miles. Incl mechanical speedo adapter/cable, back up light harness, neutral safety harness, Sidewinder shifter (positions shifter...

Green wheel in very good condition cleaned up and treated to SEM black vinyl dye and topcoat. Will make a nice driver or light resto wheel. $90+ ship PM questions or interest
