2 carb questions!

got a holley oh top of a spaceplate ontop of a edlebrock highrise rpm
holley is a 670 (i was wrong before) 80670-1 (d504)
got flowtech headers

sooo i was vaccum tuning after "resetting" the curb idle to the holley preset.. and "resetting" the carb to all box origional settings..
soo.. my question is..

is 18psi vaccum the best i can achieve? or am i doing something wrong?
truck dosent smell as rich as it did before *thank god*
its running pretty dang good..

and can i get a genralised estimate on the HP of my truck?
stock block (crate motor)
stock heads
670 holley
spacer
highrise
headers with flowmaser mufflers..

Re: 2 carb questions!

18 inches of vacuum is pretty good. My lumpy cam will only allow me 11 inches at idle

Re: 2 carb questions!

18 " of vacuum is good and cratemotor is probably not enough info for a power estimate .
