ok i was doing a 12a bridge port on the dyno...had a few peoblems.....one was on the pull in 4th the temp rose fast to 200 degrees and climbing........i know all isgood still cause i cut off in time........

BUt the big thing is timing.........checked it called RB to get the pulling marks numbers.....checke timing it was ok for L at about 23 but trailing is way
before marks on left side....most times i ave done a locked dissy si this one has free vaccum advacned..which i left disconnected.........ok my wife i needing the PC so let me know guys..any help

 

bump

 

Wish I could be more help but its definitly I timimg issue. Are headers glowing red hot?

 

thats what i think too......the stupid timing is reading good on L but way off on T....i want to believe my 6al boxes have something to do with it..but i cant make the connection.......it is driving me crazy....

 

what kind of plug wires do you run?

:AA:

 

MSD wires,....with 2 6AL boxes...non locked dizzy, but it is not hooked up to vaccum.........holley 4 barrel.....

 

It doesnt need to be hooked up the carb, they car run open vacume it doesn't make a difference. You have to check your wiring and your ground and make sure everything is cool. Some times there is glitchies in the wiring that jumps ground with other wires and cause bad timing issues

 

yea i knew about the dizzy not needing to be hooked up..I will check the ground that sounds logical
