Stall speed guess?

Hey everyone. I have a 645 C head being built to put in front of my glide. Engine finish date is too close to the first race so I have sent my old converter from the 600 A head out to be looked at. Original stall was 4600 rpm and was built off the dyno sheet.
I won't have a dyno sheet to build off of so I'm shooting for close with the intention of having another one built while I'm using this one.
4000 lb mud truck with 39" paddles, 4.88 rear gear, 1.96 transfer case and 1.80 low gear in trans.
Single carb, cam in low 0.900's lift, compression 15-16:1. 1700CFM carb from APD on Q16, Really all I know about it right now.
Hope it's enough haha!

Anyone with similar stats that can help me out?!

Are you looking for more stall speed, or less?

I believe hes hoping someone built a similar set up and could share what stall they used.

Duration numbers would help but my guess would be it would want something looser unless he's spraying it

Hey, I am guessing I need to go up but I think it would be better to be too low then too high.
I think somewhere in the 5-5500 but just looking to see what’s out there in similar combo’s
