1/4 mile times

ok well i figured out the distributer....
this is about 6-7 years old.. so most msd tech guys i talked to (about 7) had no idea what was wrong... its old technology.
instead of a threaded bolt and nut to hold the bushing into place they used to use a stud and a c-clip to hold it on.. i had to school the msd guys on it.
Thats why when i kept saying theres no bolt...and everyone sayed there has to be.. we were all just a little off haha. but no i ordered the bushing kit and ill get a bushing in there and timing will get set...
another question i had for fuel.. i have a holley 800dp a guy is going to re-build and give to me for free.. so do you think that will help with not only this build but for when i go to a solid 545 lift cam later next month???
And also with the carb spacer? its 2" should i try running without it since its bumping up the rpm range a little at least?

And lastly im having problems on converters... i called hughes and they said that there "3500" stall converter actually will stall at about 26-2800 for my big block and so on... but the cams im looking at say they kick in at about 2800-3400 so how do you choose converters base on that stall lost from advertised? i cant see how you can get real close so your not rolling before the cam jumps into action? thanks guys
