Re: help! correct redline tach for 69 396/325 4speed
In '69 at least only the solid lifter engines got the smog pump here in Canada. The others got away with retarded timing and leaned out primaries. Jetting and timing changes did wonders for performance. California was using the smog pump in some applications at least as far back as 1966.
