I took the carbs off to replace the accelerator pump and while it was apart I thought I'd change the power valve. After inspection of my existing power valve ,All I see on it is E 2 ? based on that information what size power valve do I need to replace it? Thanks in advance! 70 T/A Challenger 78 Aspen R/T 87 Indy 500 Dakota

Mine is not a stock rebuild and I run a 10.5pv. 1970 YO7 A66 [Canadian Export] F8 Challenger 340 (Currently in shop for stroker assy.)
