Just curious
Are you doing this modification to decrease or increase fuel volume while still retaining the original PV vac setting ie. 6.5 etc.
Or,is this for track use such as where performance suffers coming out of corners and a boost from more fuel is required.
Or,are you just seeking better overall street driving.
I realize many Cobra engine combos out there have cams that provide poor at best vaccum and wonder what PV's are being used,how low of a setting?
The reason for the questions is the 2 -715 Holleys on my Boss 429 run pretty well and the engine produces 10 in of vac at idle with 6.5 PV's in both carbs.
However,when I accelerate at full throttle I look like I'm leaving a vapor trail out of the exhaust.
No hesitation,just acceleration,but adding insult to injury as I bested a ZO6 and washed him with the vapor trail at the same time.He was peeved,I might say I was embarassed ,or not.
I also realize that the sewer size ports combined with dumping all that fuel at WOT may not be a cureable situation but am exploring all options.
Anyone else with 2X4's experiance this?
Carbs are from Carl's,and overall I'm very happy with the performance.
