i am having problems with my power band i seem to choke down when i realy get on it i am running a 327 with 486 hydr with 224 at .50 and 11 to 1 compression with vortech heads a performer manifold and a holey 650 double pumper worked up to 700 cfm and a mallary distributor i am wondering if i have to much carb or a distributor prob also running 2500 stall 373 gears i am debatin on going to the edelbrock 650 avs performance carb i also have a problem with cold start
thanks
dusty

is this a new problem? was it ever running good?
what is your timing at initial and total?
what is the list # on the front of your carb?

might be the intake... a performer is not really any better than a stock 4bbl..

yes and no it is cranky
total is 36 16 in
the # is 1450 or something i am not looking at it

i was running performer rpm air gap that left me with no low end so i revamped i think i am still having problems somewhere in this line

what do u suggest on intake

my email is dp23m@aol.com if anyone can im me on this prob

You mean if you mash it it boggs down and doesn't want to go? Like not getting gas or something?

Could that be an 1850? 600 vacumme secondary, if so could be opening too fast or too slow.

On a 327, I would run a single plane intake -

it has a single plane manifold i think the carb is a 4150 i will post that tomarow

what happens is when i mash the throttle it boggs like it floods i think my secoundaries need vac adjust

I'm running a 4777 model holley 650dp on my 327 and after tinkering with it time and time again I've got it running good without being too fat.
