Thanks guys , The weather was decent yesterday but not as cool as back in March , A little more humid but dang a full tenth ?? I have a spool in this rear end also and I really figured it would still be close. Changed carbs from my trusty Biggs 950 HP to a pro systems 950 and saw 1/100 difference. Everything else is still the same except for my 1" Wilson spacer. I really thought that would have helped.. Are different tracks really that different ?? Went from Richmond Dragway to Colonial Beach. Them boys at the Beach were flying .
