We use the 440 source cap, works like a charm. Helps to to take a couple thou of the mating surface for a little more squish

magnums are the only ped mount mopar i know of

There is a toaster for sale and i want to know how much its worth... That is basically what you asked of us, in return i asked for more info and you would rather just crawl into a hole... People here give smart *** answers when people are vague or ask questions that have been asked 1000 times...

Well it depends on what year the engine is, what induction system it has, race history, old factory crate motor, etc...

check that the primary blades are not in the transfer slots, if they are then you need to open the secondaries a bit, then retune the idle mix screws.

that was kinda my point, stock mag was rated at 335 or something? so it was at least 50hp more. Those stock cams had a ton of overlap compared to a modern cam with the same specs (gain low end) then with a dual plane and 750 holley it would be set.

so a stock 383...

i know of a couple of motors on pump junk running 15:1, they have big cams and water until they swap carbs and run alky.

and for the most part big motors I set the dizzy for all in by about 500, basically is just a start retard.

you have a thick skull, delay and limit are to different things. you delay (retard) or advance the curve to come in faster or slower. Limiting timing is adjusting slots or keys so the total mechanical timing is more or less. Real world example. Stock slants are usually timed 0-5*...

quench created turbulence which lessens hot spots and improved mixture as well as flame travel = less ping

go to guy for us slant guys!

Hey Dude, if your going to start fuckin around with people that are honestly trying to help you, and that are my friends you can pound sand... Were probably at 1000 posts between all your threads of ONLY trying to help. If your going to turn around and pull this **** close your account and go to...

you are a pro, but without the damn thing infront of you and 100% specs your pissin in the wind...

FIRST POST ON THIS THREAD... FIRST PAGE im not going thru the other 4 pages

yea at least a dozen times on your threads... Rusty brought it up at least once

And NO bad advice has been given to you, in any of the threads i have seen on this issue...

no i understand where you were going, we just dont know where we are which can help! Has nothing to do about it... its the fact you paid your hard earned money and got a (from the couple of pics) a marginal port job. From you pics the ports were opened up at the mouth but pinch not far into...

i agree re degree the cam. now to be fair to the OP you should add only in reference to the lobe centerline, not what the gears say as they are known to be all over the place... Op degree is as it sits so we know where it is, then we can go from there

:cheers:

lol who ported that head?

damn your right they are at .050...

exactly... EGT's are the "final product" if you will, they tell you what is going on which with other known variables can help watch other issues that may be coming up. Everything effects EGT's.

well it looks like your AFR was good, just leaves EGT's.

i dont recall what plug and igntion system he was running.

its a bummer we couldn't get and EGT and AFR curves, i think that would tell us everything thing...

except for 110 as i recall. and nothing against you just was trying to see your line of thinking

why would that change with fuel octane and timing, i could maybe see a loose wrist pin due to changes in cylinder pressure but not really sold
