Restoration / Tic Toc Tac AIM / CRG Redline Discrepancy
« on: December 28, 2015, 08:36:54 PM »
Guys I am confused about the correct Redline Tach for my 68 L30. Virtually every post here and the CRG Visual Chart says all small blocks (except 302) should have a 5000 RPM redline However, when I look at the AIM for the U17 option, it has the 6468713 part number tach (5500 Redline) identified as correct for all small blocks. The 5000 RPM Redline is identified as correct for the L34 and L35 big blocks. Can anyone shed some light on this?
