xc_rally

greetings
i am running an xc v8 302 or 351 havent measured the stroke yet factory 4 barrel carter c10 lsd electronic dizzy 4v extractors 135kws at the rear wheels dynoed at hallem performence
any guesses has to engine size from those specs
question ? which hoses do you block off to block all the anti polution gear and where to connect the vaccumm advance from the electorninc dizzy has there ar 2 egr valves if any one can help greatily appropiacted (photo from digital cam much appropiated)
also the vent system is vacumm controled i seem to loose vacumm below 1500 rpm but once i get to about 1500 hang on
suspect anti polyution is robbing me of vacum
thanks

The EGR on an XC is the EGR plate which is under the carb (Thermoquad). Sounds likes its a reasonably healthy 302.

Not sure on the Thermoquads but on the Holley's the vacuum advance goes onto the driver side of the carb under the fuel bowl.

If your running an after market bigger camshaft there is a lose of low rpm vaccum. A vaccum can is required to supply vaccum to the accesserie's.
