i have alot of time and work in the manifold and the carbs....I have had it running and broke the cam in with it....ran just great with excellent throttle response in park....but that doesnt say much.
I am also running a very wide lsa on the cam with alot of vacuum signal not to mention that the upper plenum is divided in two and epoxied, significantly reducing the plenum volume.
The manifold had a pretty small plenum to begin with.
If it is a pig on the street I have a matching pair of 390's that i can also run...but i want to try the 600's first...Id have to mount the 390's sideways and I dont much care for the way that looks...not to mention the $200 linkage.
I dont think Ill have many problems with bottom end with a 3000 rpm stall and 3.90 gears with a 26" tall tire.
Ive pulled my hair out working and researching this combo and I think itll be ok....not to say that im not taking heed to anyones advice.
God bless
