1441- .425/.395 SET-UP
« on: April 10, 2018, 06:20:14 PM »
Greetings, just bought a used 1441 w 415/395 cams and cp hi-comp pistons.
I always prefer to ask the people who are truly informed about things as a lot of you
Build them and race them.

So the basic question is on the above type of set up, what cam degree settings does the 1441  generally like for a good spread of power?

Thx in advance

What do you plan to do with the bike? Because if itís anyth other than all out race install two intake cams at 105/105 and be happy

If they are Web they recommend 106/108 but your PTV clearance may dictate what you end up with.

I ran the 415 395 cams. With a ward head and je pistons. My cams were set at 108/109. However, the issue you may find is premature wear of the cam lobes, and the buckets. Your setup may not be totally streetable. The issue will be spring pressure. The springs should not be 65lb. if street riding, they should be around 55 lb. please understand Iím not the total expert, and Iím half drunk so yea. Just trying to save ya a couple grand. If the bike is race only, I would set the cams around 109/111, with 65 lb spring, but check valve to piston clearance.
As a point of reference, I dynoed at 224hp.
Hope I helped.

I had a carpenter 1441 with 425 cams on both sides, Never did I have issue with wear, rode and raced bike on street for 3 years, and now have same top end on a 9 mill stroker and again since 2011 still have the same buckets and cams,
I think spring pressure is key I am at 60lbs from Bob Carpenter and run a good oil Amsoil Dominator 10w30
