I know Im a day late and will catch **** for this but this is a perfect scenario for one of the new Edelbrock VRS carbs . Infinite tune ability… a 750 should be perfect .

Anyone look at date ? 2014…lol

He did supply the curve . all in by 2800.

Yes but the Timing curve won‘t matter on the dyno because the pull starts at 3000 and its all in by then .

Did I read the last pull correctly? You A/F was 9.8 ? That cant help. I dont think the cam is killing you . It may not be optimal but it should run decent . looks like your torque peaked before the pull started even being too rich . 150 lbs of cranking pressure does seem low for a mild cam ...

No … not really . Dyno time is so you can break in the engine , check for leaks and find performance issues before you spend days installing , tuning , diagnosing and then having to pull the engine againe and start all over . although $800 seams spendy for a dyno shop that wont even rejet...

What else could cause the surging .

it may be bouncing in drive though . Cant hurt to try . I can’t imagine the spacer is causing this unless there is massu vacuum leak.

Then try the wire in the air bleed mod to see if you can lean out the idle without leaning out the cruise . These carbs are not as easy to tune as they say . Certainly not on a modified engine .

Low speed light throttle only uses the idle circuit so it could be that you need to use lighter springs. The metering rod might be bouncing up and down . I dont think timing is an issue . I run a very similar cam and it will run OK anywhere between 12-18 intitial. I also think your lash is...

https://boyzunderthehood.com/wp-content/uploads/2018/11/EDELBROCK-CARBURETORS-ADVANCED-CARBURETOR-TUNING-IFR-BIAB.pdf This is a good read . And the mods worked for me . I have a brand new 800 AVS Thunder but its a good learning experience to mess around with with the 1405 . The car runs great...

I have a 1405 on the Barracuda right now and have had similar issues with excess gas smell no matter how lean I ran it . I ended up installing a thin wire in the main air bleed circuit to lean it t out some . I will try to post a link on the procedure.

Maybe exhaust valves are a hair too tight and pushing some raw fuel into exhaust system ?

360 version vs W2. there are quite a few differences. Mostly in the deleted or undrilled fitting bosses . Which allows the runners to be cleaned up without fear of breaking thru to a bolt hole or having a gaping hole to disturb airflow .

except the crossover , EGR and choke well were cast into the production version . I am not sure how much work was involved in deleting them ? But maybe they tweeked some other items in the process . ….

That would be a cool piece to have .

The point of the thread was to peak curiosity and show a novel Mopar part . Have had many people say they don’t exist over the years .

I don’t know if the deleted cross over etc freed up any runner routing to allow better flow or porting potential. Would need to compare side by side.

I sold a NOS M1 Dual Plane to a member a few years ago . Can’t remember who though .

No crossover, no EGR , less hassle , more cool …lol

I will overlay some W2 gaskets and post a pic .

I need to find a stock one to compare side by side to see if there are any runner differences. Mopar had to do some casting changes to eliminate the cross over , choke and EGR so maybe they gave a little help to runners ?

Yes … that was him . Had great oil mod info long ago l

Could be ?

Would be a great piece for a FAST class A body !

Winner winner Chicken Dinner ! It is a factory cast iron W2 intake made to cheat roundy pound classes that require stock cast iron intakes. But rumor has it that they considered W2s for the Little Red Express as well as rumors about 80/81 pursuit packages being equipped with W2s. A very...

Oh yeah… cast iron

[FOR SALE] - 340 Intake Manifold 72-73 TQ Casting # 3671918 @66fs sale post got me thinking about it …

Hint… check out the bolt hole spacing .

I have owned this intake for a while but never noticed the lack of crossover .
