YEP AFTER 30 years I CAN GET VERY CLOSE BUT YOU AND I DON'T CHARGE 850+ DOLLARS ,,,,AND NEITHER SHOULD HE TO HAVE THINGS CLOSE ,I LIKE MY STUFF RIGHT AND THERE ARE TO MANY VARIABLES TO GET 850 WORTH OF CLOSE FOR ME ,ABOUT ANYONE CAN GET CLOSE ENOUGH NOT TO BURN DOWN THE ENGINE !

MY 2 CENTS WORTH ,YOU GUYS HAVE ADD IT

NOT TRYING TO ARGUE JUST HELP SAVE SOME BUCKS

I have used 4 of Deans carbs and they were all within 2 main jet sizes of being perfect. Idle good with no black soot on the transom!!! We are talking severly over cammed motors here according to the OSO crowed. My little 496 has throttle response like fuel injection with a "to large" stage 5 1050 from Nickerson right out of the box. Worth every penny of my $1095. Only my opinion, based on my experience. By the way most stock Holleys will run leaner than a Nickerson at WOT. I see guys with stock carbs getting sooty transoms and start pulling down the main jets to fix the soot problem. Man are they way off!!!

Never use more than a 3 angle valve grind on a marine motor. With a 5 angle grind the contact area is too small and the valve will overheat.

Yea, keep the seat width at .100, .075 minumum for valve cooling.

Yes,,,,what Tinker said on the 5 angle valve job !!!!!!!!!1

JUST DEPENDS ON THOSE VARIABLES AGAIN RPM ,COMP.,ECT....YOUR RIGHT MOST STOCK CARBS DO RUN LEANER THAN DEANS ,PERIOD AS YOU SAID IN YOUR NEXT TO THE LAST (ABOUT) SENTENCE VEN STOCK YOU SAID YOU SEE GUYS PULLING OUT JETS SO IF THEY START LEANER AND THEY GO EVEN LEANER ,YOU SEE MY POINT AND SPELLED IT OUT FOR ME !!!!
I'M GLAD YOU ENJOYED SPENDING 1096,ON THOSE RICH CARBS!1

JUST TRYING TO HELP !! VETTE USE WHAT EVER TRIPS YOUR TRIGGER !!!!!!

GONE TO THE DYNO TIL LATER BUT I'LL CALL DEAN FOR HIS HEALING POWERS DON'T WORRY I WILL NOT NEED DYNO OR WEATHER INFO ,,,,,SUUURE LMAO

THIS IS NOT WORTH ANYMORE DEBATING ,HAVE FUN !!!!

I am not really debating this, only stating some positive feedback about carbs I have used. I am not trying to sell anything or trying to negative sell anyone's product. I am only giving an example of some good experiences I have had using Nickerson carbs on HP motors that didn't go on the dyno. Some people on this board are in the marine business and I think that is very helpful, but many times their helpfulness is actually only a negative selling tactic which really doesn't work with smart consumers. As for $4600 it seems a little high to me. However if he is promising results and dyno numbers to verify them and if he stands behind his work it may be worth it. I know you could get it done cheap, but as we have all seen on this board in many cases you get what you pay for. Good luck!!

LOOKS LIKE YOUR YRYING TO TELL YOUR BEST GUESS AS TO WHY YOUR CARBS WORK AND I'M TRING TO PROVE THE CONVERSE !!
I'M IN THE MARINE BUSS. BUT NOT TRING TO SELL MY WORK JUST TRING TO SAVE SOME PEOPLE SOME WASTED MONEY
AS I SAID I'M GLAD YOUR HAPPY ,BUT
WELL ENOUGH SAID ,GOTTA GET TO THE DYNO ,WASTED ENOUGH TIME ,PLEASE FIND A TRUE TUNER OR ENGINE BUILDER ANYONE ,ANYONE CAN HIT AND MISS UNTIL IT RUNS

HOPE SOMEONE BENIFITS FROM THIS ,JUST REMBERED THE INDEXING THREAD ,WOW

I think the price is high for what you are getting, shop around and deal with a reputable builder.

Keith is a real great guy - a little slow - but really nice to work with. He's the one who dressed my 502's....
And who do you think does HIS engine work?....the same guys who have my engines!

Okay...so if YOU guys had to rework a 502 upper end - what parts would you put into it? I want around REALIABLE 550 h.p. out of my (current) 415 h.p.
I'll skirt the carb issue for the moment - but I do need an intake manifold. So...cam, spings, valves (or do I just purchase a new set of heads), intakes, rockers, etc....

Again...I'm the village idiot when it comes to engines. I have no problem buying parts and giving them to the builder if it will same some cash. I have WAY too much into these engines right now - it's getting to be a grudge f*ck at this point - I just want them DONE.
