Does someone have a copy they could send me?
I have one but it's in a package. I'll look tomorrow if noone replies tonight.
thats a big boy!! Gonna sound nasty!
I may have one. Will look
Here you go.
Thank you very much Dan.
Your welcome. Luckily I had it on the cam box I had all packaged up for someone who backed out on sale and I forgot to put it in the box! Lol
Does anyone really run .030 lash cold?? Would be .035 hot with aluminum heads! That's alot!
How did the 508S run compared to the custom grind I bought from you?
I ran the lash at .019 cold.
The custom grind was a tenth quicker.
I would think .030 lash would be hard on the roller rocker roller tips and the pins. I ran my 308s at .023 cold and it was real noisy. I run .014/.016 now.
I ran .019 cold on my 259 267 630
