Do you know if the Doug Eichner is the same as the 450s upgrade.... i know that the Doug is a 39mm (38.8 mm) .... what is the Edlebrock upgrade size to the 450, does N E one know.....?????
I would think they would go smaller for the acceleration side of things.... 42 is BIG :blink:
That is also what I have found out first hand.Originally posted by alex1212@May 28 2006, 10:49 AM
they work well with a near stock bike. once you do hc piston, bigger cams and head work it gets difficult to find the correct needle. i dont know if they have changed but last i looked they were 40mm
