1969 Judge Engine block
 

Am I right in thinking that the early 1969 Judges used the two bolt 9790071 block which was later changed to a four bolt set up, the 9799914 block? Appreciate any information on this. Many thanks

69 RA3 are 2 bolt main. RA4 is 4 bolt main. 9792506
0071 block for 69
9799914 used in 70. both 70 RA3 and 4 are 4 bolt main. 9799915 RA4

Pontiacman, many thanks

1969 GTO Ignition upgrade
 

I recently installed a Pertronix Ignitor in the distributor and threw out the points! Works perfectly except that the hood tach no longer works. Has anyone been able to solve this problem

i think the manual says you need a resistor wire in series on the tax lead?
