Getting ready to go back to the strip and need a little advice. I have a full weight 69 Dart with a 360/727. The 360 is about 12 years old and has about 40,000 miles on it. Dry wet compression tests show 170/195 except #6 Was 160/195. The motor has an edelbrock 650carb, edelbrock air gap, x heads, tti headers and a comp xe284 thats been advanced an additional 4 degrees.the 727 has a 2400rpm stall w/ a shift kit. 3.55 gears and 235's. The car has run 13.40-13.60 @102-104 on drag radials and 60 ft's were bad, 2.10's.
I have an opportunity to buy a 3.91 gear 3rd member for a decent price. Would it really help me much over my 3.55's? In a perfect world, I would buy a better converter and rebuild the 360, but I'm broke and wanna try and get into a high 12 before I rebuild this thing. Any advice or suggestions are appreciated. Thanks.
