Stock 318 with garbage valve guides and mileage Stock best it ran 17.8

Changed to stock TQ intake and headers and 2.71 gear as 16.8

Changed to 3.55s and curved dist 15.8

This was in a 3950 car Plymouth Sat

Yes Pigs can fly that car proved it The one head were so warped that it could rock but thick head gaskets took care of that problem

Advise stick to what you in tend to do a high stall is recommended but I stayed away See if you can finc a factory 2200 stall they worked well on my other car . No headers then get a a exhaust cutout cheap good power

With LA heads I push my timing as high as I can often in the 43-46 degree range but every car is different. My advise here is a accell dual point dist and or pertronix conversion cheap power with out vac advance

Have fun!
