this is what i wanted !!!!! you guys are great, thankyou so much.

ok. my 600 holleys have had uprated power valves and the springs are stronger (somewhere in the carb ?)

as my carbs are back to back and not side to side i could only fit 1 x metering plate on the rear carb as there wasnt enough room on the front one as it would hit the rear primary casing ( thats on the secs ).

i explained this to the performance guy my side and he said that in a perfect world i should go side to side but he felt i could get them flowing well as its only 1x carb that doesnt have jets in the secondary metering plate.

i have a book on carbs for supercharges and also the well known supercharging book that is mentioned on here. i am happy with the weiand blower and feel i can get a nice reilable ride out of it and hopefully around 600bhp ??

i will check what timing it has at present and check the starter motor cog.

i feel that i need to get it running better and then start fine tuning the carbs to get the lumps and flat spots out of them as i go ??

at some stage i need to go to the rolling road that specialises in my ecu software and get it tweeked , but how long should i wait until giving it some on a dyno ??

good point on the possible air issue. i will double chech that one. that does add up as it gets bloody hot at the end of the headers. glowing red !! i do have exhaust wrap though so i expect a bit.

i have checked the float bowls and they do not have leaks. one of my needles was sticky so i changed that.

my money is on timing and carb set up issues.

guys , on my holleys can you reccomend from the start what mods i can do to my carbs that would need doing anyway ? (ie set up for supercharging ) i bought it as a set from a guy who had them on his car for a short while before the wife decided to take him to the cleaners. but i didnt hear the car running. so i would like to treat them like they are not set up for blowers !!any good advise ? or should i get it running first then start drilling, moding and changing bodies ??

with all that said once running what sort of power do you all reckon ? its been a long 10 yr project this

did you look on the you tube clip ?

thanks alot guys. awsome !!!!!!!!!
