JMO.. I removed my points system and went electronic,, I removed the 1 3/4" exhaust system and added 2 1/4... removed the battery from under the hood and put a fresh air retrieving system in so I don't try burning 200 degree air.. I removed the single barrel carb and intake and replced it with a Offy aluminum 4 barrel with a very small 390 cfm Holley... I put the good NGK plugs in and it woke my 66 up..
No more problems getting up moutons or pulling into traffic and runs cooler.
with the factory 3.23 gears and 14'' tires it runs a 11:30 1/8 mile now and I bet it was running a 14:30 before, This was dun to a low dec 170/ and my gas milage went up to about 26 mpg. Know I have everything on my 66 (my daily driver) ready for my new big valve head and just a slight shave off, about 40k off of it.
I know this is not a screamer :happy8: But it can get out of it's own way now.
I really think the cool air supply and larger exhoust and changing to electronic was the kicker here.
