Hello all,

I am currently in the planning stages of my next motor for my 67 mustang coupe. I already have a ealry 90's 351w truck block. I also have a set of eagle H beam 6.25 rods with chevy sized journals.

I am trying to decide if I should make a clevor or windsor 408cu.  I also have a set of 71 or 72 4v open chamber heads. They are in good shape, If I use them they will be gone though with new valves (one piece stainless) and hardend seats etc.

A little about the car:

First and foremost, its a street car. I have no diluted dreams of a 10 second street car. It has to run 91 octane, 93 is kind of available in my area, but 91 is more prevalent.

Car is an automatic, it already has a TCI street fighter with a 2400 stall converter, but I wil change converter if I need to. Its getting an 8.8 with either 3.27 or 2.55 rear gears

now for the questions:

1) what is the HP limit of the heads if it does turn into more than a street car.

2) What kind of HP will this thing make if I shoot for 10-1 C/R and get a custom cam to get dynamic C/R to an acceptable level?

3) what C/R should I be shooting for with open heads?

4) Am I better off just building a windsor stroker with RHS 225 or similar heads?

Clevors are cool but not worth the  trouble IMO. A well thought out Windsor will suit your needs.

The Cleveland heads are great, but the whole idea has to come down to the supporting parts. Can you get an intake for what you want(EFI or carb), the headers, and the accessories(brackets etc)?

I'm aiming for a 351 Clevor(8.2 or 9.5 block I'm not sure yet), EFI and Explorer front dress, and a 4R70W. The heads to allow the later accessories will have to be CHI 3V heads, since they are the only ones that include Windsor holes for the brackets. But those are what I wanted anyway, if they are big enough(I'm not convinced by their advertising saying a port almost the size of a 2V port will flow like a 4V port).

I have real 4V heads also, but I can't use them for anything I've planned.
