Comp Cam adjustable valve train 403

[Gold member]

I added a set of good used #7 heads to my 403 big difference in power and exhaust sound. I ended up with a small rocker arm tick so i am going to add a adjustable Comp Cam 1441 valve train kit . Has anyone used this kit ? any tips on install ?

You'll possibly need custom length pushrods to suit your engine and heads.

Wondering why i would nee that The kit is made for a stock 403. Motor still has the stock cam from 1979 is all original except the heads . Spoke to the machine shop that inspected the heads valve stem height could be off for non adjustable valve train they suggested this kit. Not looking to make it a race car just add a little HP. Before i took off the 4A heads the motor ran and sounded great no tick. Thanks for your thought on this .

You no longer have a stock 403. The replacements may be of use but rarely are. An adjustable pushrod will determine the length you need and then compare.
Stock length 350-403 pushrods measure in @ 8.265". The 7843 pushrods supplied with the 1441-KIT are 8.500". Different valvetrain design obviously. My rebuilt 403 and 4A's skimmed once required 8.400". If either have been rebuilt in the past, or machined or had new valves put in, it becomes an unknown. Again, may be just fine.
