750 or 850 for 351w/393 stroker
 

any suggestions on what size carb to run? MM&FF had a 393 stoker make 536 hp with an 850 speed demon, but every carb manufacture recommends a 750. MM&FF's motor is really similar like really close to my combo, see below for details.

Go with an 850, and try two steps smaller jets at opposite corners (one primary and one secondary). Your engine is going to be running at high enough rpms to pull the fuel with no problem, but the amount might be too much. You may also lose a little off-idle response, but who cares. Off-idle is for parking and loading it on the trailer. ;)

thanks but i am not even close to a carb guru, to me that just seems like voodoo.

is that kind of difficult or is it pretty straight forward.

i dont want to buy a new carb and then mess it up by tinkering with it.

could you elaborate on that process?

thanx

It's very straight forward. Get an 850, try it, and if it needs adjusting, email me. I'll walk you through it.

i would use a 750 annular race carb. since that motor will not see higher than 6500 rpm you really dont need more than that for a 500 hp 351 at low rpm. there is a reason why all the companies say 750 ya know. pkrwud knows his stuff too but i have to say 750 on this one. or you can just meet in the middle with an 800. that might help out with the having to drop jet sizes and losing low end response. what do you think pkrwud.

thanxs for the 411

i have been contimplating about which carb to run for quite some time now

i want to buy the right carb the first time know what i mean.

i put three years into this motor. alot of blood sweat and tears into this

i spent the money in the right places, or at least i think so, so i dont want to make a stupid mistake now.

iuwant this car to run like a scalded dog.

A 750 would work, but it wouldn't flow as well, IMO.

You have to tinker with or it won't run the best. Its called tuning. ;)
