I have an Uncle that has a 70 Mach 1. He hates the inter-net and wants to know the answer to this.

He has a bone stock 351 Cleveland with 73 open chamber 4V heads. The motor only has 30K on it since the last rebuild. He has 9.0/1 flat tops (no valve relief)and Double Springs to .600 lift already on the heads. He babies this thing. Now he has a buddy that has a 68 Camaro that beat him last weekend at a musclecar showdown and now he wants to "smoke that turkey"

I am giving him my Edelbrock dual plane intake to replace his stock cast iron one and an 800 DP. this is a 4 speed car too.

He wants to know what the largest lift cam he can install in this motor? Without replacing or upgrading anything else.

It doesn't work that way, you just don't go stickin in the biggest bump stick you can find.
You've gotta change EVERYTHING else to match what cam you're stickin in or you'll have tons of problems

I agree with Ray (not totally though)
put some gears in it! this is the most effective way of makin it quicker, I wouldn't go with a 4.86 though, maybe a little bit more conservative like a 4.11 or 3.91, I've got 4.86 in mine and it doesn't go on the highway

This is only an upgrade. He does not want to set the world on fire and race every weekend.

He has 3.91s gears in it now.

Plain and simple. Stock Cleveland. Cam upgrade. How big can the lift be without banging the piston?

Or better yet.

what is a good cam dimension that he can upgrade to get the most bang for the buck?

Your not tellin him the full story though, you probably had huge valve reliefs.
It can't be more than .590 because when I had my original cam in it had .569 lift on the intake and when I ran it down to the piston I only measured .060 of clearance and thats gettin kinda tight in my book.

They didnt have that big of valve reliefs in them. With the dome shape of those pistons its almost impossible to put a very big valve relief in them without cutting the dome down.

It's all pretty irrelevent if he's gonna run a hydro cam anyway. Anything that is gonna work correctly for him isnt going to be anywhere near hitting the pistons.

MrXerox: How do you like that Comps Cam? I have often looked at it as a possible option...

Dont quite have the whole package dialed in yet but you can tell the motor really likes the cam. If I had to do it over again I would have saved my money and gotten something around the same profile but in a non-roller as I dont think the power I gain with this small of a profile really warrants the extra costs of the roller. Ray has this same stick in his Stroker Cleveland and it produced over 500HP! The thing I like most about it is it lets me use 91 pump gas and will allow me to hook up my 150 shot bottle in the future by bleeding off some of that cyl pressure with the 110 grind.

Does he have headers? Really need good headers if you are going to change out the cam. You've already taken care of the intake side.
