What will hook up to a 351 Cleveland

[15wildea]

I found a good deal on a 351 set up for drag racing already which is cheaper than rebuilding my 390 will a zf bolt up with some conversion

The Clevelands share bells with the 302 and 351W, so as far as bolt up goes, those would Flywheel would be my one concern trying to get a ZF on it. I'm sure there is a way, but it won't be a direct off the shelf option probably. Not sure what the crank bolt pattern and balance is in comparison to the 302 or 351W.

ZF is a 10spl input shaft IIRC. So the Cleveland clutch should work.

 

[Fellro]

Next issue to resolve would be the hydraulic clutch setup, there is no fork on the ZF for small blocks...

I'm betting the internal slave cylinder would work, should contact the pressure plate fingers the same.

I was thinking the pedal end, but that end also needs checked.

Just make sure its a Cleveland and not a tall deck 351M or 400.

Hydraulic clutch is a bit of work but an easy conversion...

SBF bell housing and 351M/400 exhaust ports, quick way to tell.

I say this, because I have one sitting in my shop waiting for a good engine bay...

I was told on another fourum that a zf s5-47 should hook up but isn't that for a diesel?

 

[Fellro]

They are both. If you need a provision for hooking up a speedo cable, you will not be able to use it. For ZF's that have speedo cable capability, you have to go 1991 and older.

Why wanting a manual for drag racing? It'll be slower than a properly built auto.

$20 says he'll be bracket racing. While the slush box makes it easier, a manual can be just as consistent...

I agree 100%

Yes...consistently slower

 

[1970Custom]

Don't matter how fast or slow it is... I've seen a 20 second Bug with a manual beat an 11 second Fox...

 

[DNFXDLI]

If you are bracket racing, sure.

 

[1970Custom]

Yep, I already hedged my bet that he is...


But, my drag car will be a BBF and a well built automatic.

 

[DNFXDLI]

There is hope for you yet

I haven't known ZF's to be fast to shift. I have however, known the shifter to break off...

And they don't float gears for chitt...
