| To HIC, from EFC. X2894 EFC6A/ 12.12.27. Herewith we hand you the contact breaker unit which you arranged for test with the .080" thick anvil. The result of this test is poorer than the .064" which we have previously tried, and which we are running on experimental cars. We should be pleased if you would re-arrange this with the .064" anvil. We would also like to have a second quicker break cam, as there seems some improvement in the results of running the combination of quick break cam with the scrubbing action. Would you please put one in hand. EFC. | ||
