<VV> Kind of gas for 62 Monza 110

[James Davis]

My 68 UltraVan came with a 110 smog engine, Tonawanda  code RW.  It had the
open chamber heads (95 hp) but pop-up cast pistons giving a compression
ratio of about 8.6:1. It would knock on 93 octane gas unless the
distributor was retarded about 6 degrees from the stock initial advance of
12 degrees on the 319 distributor.   The RW engine was soon replaced with a
relative stock 65 110 AT engine.  It was still so sensitive to knock that I
installed a Ray Sedman supplied Safeguard to quell the knock.
