Red 409 63 impala
Well Known Member
I am trying to do a compression test on my 63 409. My tester I have had for a long time and used on a lot of small blocks will not attach and screw into the head. Looks like I need an adapter to allow my tester to screw into the threads in the clylinder head. Has anyone used a adapter that worked well and what is the part number.
Thanks.
Thanks.
