1972 Dodge Colt
A few interesting discoveries working on the engine.
I put a dial indicator on my Cox/RAS? Roller rockers.
Marked with a 1.5 under roller tip.
They were purchased as 1.5 rockers.
They measure as 1.6 rockers!
I wanted to check the spec on a Roller Cam I purchased from Cox Brothers a few years ago.
No cam card furnished.
Now that I have some roller rockers I can run the numbers.
Problem, It won't clear the cam bearings as it goes in half way.
Now I know it has never been ground.
I used 3 copper gaskets to add deck height so I could check piston to valve clearance.
I got a measurement Saturday after I got some Manley 7 deg. retainers to fit the valves.
What I measured was what I expected with this big head cut.
Now I need some springs.
I made many trips to my machine shop today on cutting the pistons.
He could not use the direct connection instruction for valve notches.
He let me borrow a transfer punch to center punch the I and E centers.
