Re: Dual x450's with model e's///pics fixed

yes they do, even with a 14 inch air cleaner mounted on top of them...you will need the low air filter tho and keep the stud real short.

Re: programmable ignition

I wonder will the blackbox work on my small block chevy, i have a mallory unilite dist tho. Im not sure how to lock that out, ill have to look into it. This seems like a good way to make the timing curve needed.

Re: Dual x450's with model e's///pics fixed

Ok ive fixed the hard starting problem with an impco sv connected to a momentary switch and the vac hose in the base plate, gives it a nice shot and fires up after only a few cranks. As for the timing i was able to get 16 degrees initial, 14 degrees advance and all in by 3200. That was the best i co...

Re: Dual x450's with model e's///pics fixed

Sorry i havent been back, messed my ankle up pretty bad, ill get to this asap. I wont be doing any wrenching for about 2-3 weeks. The mallory kit at least will limit my advance to 16 degrees, i should be able to set the initial from 12-16 to see what happens. My concern is heat and how the plugs loo...

Re: Dual x450's with model e's///pics fixed

Going back to the timing, i didnt want to change the distributor but i think its time to swap it out for a hei. I can only do so much with this mallory unilite, 10 initial and 30 total is all i can get, After that the two go up together, next ill try the 12-32 but i think under load it will ping wit...

Re: Dual x450's with model e's///pics fixed

Might have it fixed with more timing, have to give it a good run under load to make sure but so far so good.

Re: Dual x450's with model e's///pics fixed

Its tuned in pretty good now, revs nice and clear and seems to have real good power. It still tho has a slight hesitation but clears up right away, i tried messing with timing and some afr adjustment but it seems the same.

Re: Dual x450's with model e's///pics fixed

Ive been running this this around alot lately,ive been getting a hesitation when you step on the gas. It goes away pretty fast but its there. Other than that it runs great and has lots of power thru the prm ranges.

Re: Dual x450's with model e's///pics fixed

Ive been adjusting the afr by watching my digital wideband with heated o2 sensor. The metering rods are at a pretty good setting, when i first fired it up i had to Lean the idle mixtureand the idle speed. After that it seemed to run pretty well. A few things i can try tho : I can try the other washe...

Re: Dual x450's with model e's///pics fixed

With the 4 cylinder jet in the vpv it still smells like fuel and just cranks. Disconnected it cranks and just fires right up, I can prob lean the idle mixture pretty far to get it to work like you said, ill give it a try when the rain stops. Should i put a tee in the ports in the one vpv and run it ...

Re: Dual x450's with model e's///pics fixed

I ordered the smallest jet for the vpv, its smaller that 1/2 the size of what i have now. I was told its the 4 cylinder jet, that might actually work for what i need. I did get the low fuel light to go in the pressure line, since i turn one tank on at a time it will go on giving me time to turn the ...

Re: Dual x450's with model e's///pics fixed

No big deal on th vpv's, im going to call monday to see if i can get the 4 cylinder orfices, I think the ones i have are the largest for the v8, if i can get the smallest one and run one it might work out for me. Its worth a try and they are real cheap, i think they are under 10.00 a pair shipped to...

Re: Dual x450's with model e's///pics fixed

Aslong as its all working good ill let it alone, what worked real good was i bolted on both carbs one at a time and tuned them to have about the same afr#'s. Then when both bolted to the adapter the truck fired right up. I tried using impco vpv's and it just floods itself, they are still in the pics...

Re: Dual x450's with model e's///pics fixed

Yea its the same .040 over 350 12.5:1. It seems to have more power all the way thru. Even off of idle it seems to pick up alot faster, It revs pretty crisp and clear to 6500 plus.I used a 750 double pumper base plate for the adapter, new gaskets, new screws and cleaned the carbs. This won't be on th...
