427 SBF

@Mike Beck I'm bored waiting for parts.. so here's a drawing.

A (gear machined face) and A (camshaft face) on the drawing are drawn together and butt up to each other when the bolt goes in.

And yes, shaving the retainer plate would give me the clearance needed. I tried that and had no luck, so I'm going with the torrington setup.

 
Ed Curtis does not mind having 0 end play if there is a Torrington bearing. He wrote that in a thread somewhere on YB.

I do recall seeing that.

My only problem with that is if something is fucked up and I have "negative" endplay and I'm squeezing the torrington. I don't know how "freely" a camshaft should spin without the chain on, so I'm just guessing at that point.
 
The cam should spin very freely with no timing chain. When I took my wives engine apart, once I got the rods and pistons out I gave the crank a push and was amazed how may revolutions it made before stopping. I wasn't expecting it to turn so easily.
 
"NEARLY NOTHING" Not zero. See how shit gets lost in translation? :D

'60s-'70s Vette rear spindle play is like that.
The engineers thought that zero play is OK, but they specifyed .001-.008 in the manual.

They know there's a big difference between zero meaning "the parts just touch" and zero meaning "the parts have been tightened together".

What's the latest ETA on completion and hitting the street?

I've given up on eta's

I'd like to say it'll be assembled early/mid week then dyno time if they haven't disassembled the dyno yet. If they have, add 3-4 more weeks.

I'm not putting this thing in my car without running it on the dyno. I have my reasons

If it doesn't run the numbers you want are you going to smash it to bits and buy an LS? :lmao: :lmao: :lmao: :lmao:
