Me, being a dick for fun...

"Hey I'm looking for some pinion shims"

Oxreilly's - What's it going on?

"A 351 windsor crankshaft"

O'Reilly's - *silence*

"Can you just search if you have any pinion shims at all"

O'Reilly's - do you know what vehicle it's for?

I was watching Roadkill Garage and they were doing a Windsor and said something about the need to check the crankshaft sprocket and shim it correctly. Sounds like fun and something Ford people learn about. We don't have this issue with CBS & BBC stuff. I never dealt with tearing apart late model stuff (LS style).

Yeah, but look how ugly yer intakes are, and headers on the sbc, bbc headers are tolerable at best 😏
 
I have also verified the valve opens .050" at 10.5 degrees BTDC as stated on the cam card.

It actually cracks open .002" 42 degrees BTDC, and .01" at 31 degrees BTDC if anyone cares. Maybe useless info, but I'm trying to learn about valve events and I find this stuff fascinating even if I'm wasting a little time here
 
The first .100 of lift takes roughly 49.5 degrees to get there (with .100 lift coming 4.5* ATDC)

The next .100 takes 24.5*

Then 26.5*

That says something about the ramp rate on the cam. And my thoughts would be taking longer to get the intake valve open might be a good thing, as the faster it cracks open, the more potential exhaust gas you'll be pushing back into the intake as the piston is coming up?

I might be completely off base with that if anyone with more understanding wants to chime in.

You can put it on a graph to help.
Scavenging is your friend.
 
Fuck this tool. Off to buy something that doesn't suck

 
Also, here's the as cast promaxx project x heads. The look nice, we'll see what they can do

Yeah, those suck! I would say get the LSM spring compressor, but the Moroso stud mounted compressor is pretty trouble free and way cheaper.

I have the LSM for the shaft system in my car. I use the Moroso tool on "normal" stud stuff like the wifey's engine. I even have her help me. She disassembled one head, I will have her put at least one back together, she likes doing this stuff.

Carb-style intakes look fine. My headers, well THEY SUCK! I absolutely hate the design of the SBC exhaust ports, JUNK! BBC are fine. LS are fine. And the rockers that are crooked drives me nuts. Such a dumb design. Pushrod, stud, and valve should all be inline. I have to use an offset rocker and lifter in my engine to get this shit right.
