    Fastest NA SSS

    Well Im going at the fastest SSS record (12.14 with a 427cid) again this Saturday at Fontana TNT drags. Only change this time was a bigger converter. Went from a 258mm 3B (3200-3400) to a 245mm 4C (3600-3800). As of right now the shift extensions are about 400rpm higher and it flashes higher as well. The old converter flashes at 3k rpm with a best 60' of 1.69 and avg 1.74. My PB right now is [email protected] 1.699 60' [email protected] 1/8th Mods are 370, ported heads, ported lsxrt manifold, full boltons, converter and 4.10 gears.
