400 and purple cam

Asking a question here. Isn`t 36 in at 2400 a little too quick for todays pump gas? That's the way we used to run them when we had good gas. I`m running 21 initial, 34-all in at 3400. Is my thinking wrong on this, w/ 91 real gas ?? All opinions welcome !

That 400 piston is close to .200 in the hole at TDC. I think he will be ok........of course no way to tell but to try it.
