Ps anybody want to look down a vs carb to see when it opens on a dyno during a pull? Sometimes they dont open until 4000 + rpm

they work like a vacuum secondary . If the secondary air valve opens to quick it bogs if to slow its lazy. the nice thing about the primary rods is you can change the jet size without changing the actual jets just by metering rod size. if the secondary air flap opens too quick it bogs because...

Standoff from what ? Is the engine turning backwards? Is the reversion now so bad that its blowing the fuel backwards?

Also are the carbs balanced ? As in equal air flow.

just an opinion. The secondary air doors are opening too quickly need to slow them down, keep tightening until stumble goes away . You could keep throwing larger squirters at it when the originals were probably ok.The original jets were probably close . The plugs look and probably are too cold...

Your right no stats no facts no comparisions . I dont think I showed anyone anything just came here to argue with every one. I cant prove anything . Im out.

I guess I viewed it differently but rereading it - Your right! Sorry for the confusion.

Modern lobes are sometimes better sometimes not but the power difference aint no eye opener.I also said roughly same lift . Remember these lobes are rated at different opening points so sometimes smoke and mirrors. Remember racer browns lobes were designed in the 60s and 70s

So, to recap ,I already knew about the cams, my point was not that I needed an answer ,but to show that like cams will produce about the same power.No one said anything about rocker ratios but everyones an expert on cams.So to the people led down the garden path by some posters,the point was...

Howards bought Custom Camshaft Co which also had Harolds lobes

As far as I remember they went from engle to howards no bullet.

Hey in my world by-by means your gone . I guess we cant be that lucky .Now go start your own thread dirtbag .

YR theres no need for you to hit the disagree button with my last post.You at the time did not even know that all of ud harolds lobes were bought by bullet . So much for telling harold what to do you must have had his personal cell number.Did I tell you that I told joey amato in his parts store...

You know YR YOU must have missed reading comprehension I Dont need a recommendation it was about comparing lobes I dont want a recommendation or comparing between different .050 or lsa . I remember when you first started your lying crap you didnt even know who bullet was or...

You guys are missing the point . Its not about customs or whose company is better its about comparing company a to company b with the same cam specs. My statement was your not going to notice a difference between a mopar grind or an engle given the same specs.So when some one says use a jones...

hp is for mph but not necessarily et. Bigger ports/valves dont mean they will be faster

YR now why you gotta be like that? (we all know youve walked across the desert swam the ocean,been on the moon) but my post was not serious when i said 50 hp. .My point was that on a street cam with same at .050 same lsa you are not gonna find a bunch of hp. as PRH said. As far as reading...

Just a wild guess .... the magnums will make the same or a little better et than the sm heads. I didnt say hp i said et.

I dont want to learn.I just want to know how some can justify saying some of this crap. Such as the newer profiles make more power apples to apples same .050 same lsa how much power diff. is there?How about 1.5 to 1.6 rockers there must be a gazillion on a street engine.My point is the marketing...

Seems theres always a cam question. The answer id like to find out is when a statement is made about newer grinds vs old if both were compared on a dyno would there really be a big difference?Would it be worth the change? Are we talking 50 hp diff. if comparing same .050 durations similar lift...

As far as the stocker cam . Sorry not without 5500 converter and 5.13 gears.

thinking with a 3500 converter the rpm range should be around 35-5500 the 484 should work.An increase in compression will help plus the tight lobe separation -108 will help Ive seen where the speedmaster heads didnt help much on a sbc vs the double humps.Dont be misled that there the end all be...

I say keep your cam ,use your magnum heads change the converter and gears and work it from there . The rpm range is kinda extended with the 323s and you have to make the most power/torque there . Even though i dont always agree with yr ptc has the best value / quality converter.If your rpm range...

To me what your explaining is a engine with a bigger than needed duration and a wider lobe separation to kill off some of the bottom end and make it up up top.Thats why i previously suggested tightening up lash to do this.It doesnt hurt anything plus its free!

For some of us its not as easy/controlled as it could be thats the reason for the clutch tamer.Id also be very interested as to approx what cam should be in this with a stick to help him leave softer.

Isnt the trick to use lower pressure with enough flow. If at 5 or 6 lbs there is enough flow use it .At 7or more lbs isnt it aerating the fuel in the bowl more??

So now it doesnt sound like a bog but a fuel delivery problem? Prh is right but also could be jetting . the holleys with the big sight glass gives a goofy read,better to set off the carb, inverted .Also dont go by street launch compared to track . Track might still bog

Maybe just maybe its not the carbs maybe the converter is too tight for the cam and nothing you do is gonna help other than changing the converter or the cam. I have seen this before and while carb tuning is good and interesting its hard to fix a problem that isnt there.
