Hey everyone Great news!! I went to Test and Tune @ Desoto today. My previous best time was 14.04 @98 MPH. That was with all the original parts with 145000 miles on them. After the install of a K&N Walbro 307 fuel pump new timing chain Valve springs slicks open exhaust and my new SMC Alky Kit I went 12.85 @103 with a 1.79 60-foot time!! Im thrilled!!! This was at 19 PSI 26 Degrees advance and using 93 octane gas. I used straight Denatured Alcohol which worked perfect!! Later I raised the timing to 29 degrees and 22 psi and still had no knock. Lack of traction made the times the same but it felt a lot stronger. The car has the stock rear rubber bushings so when I launched harder than 5 psi the car went kinda sideways... Definitley a fun ride!! 11s Here I come!!!
