Gm big block 454 to small block ford zf5

[maverickwhiting]

I am throwing around the idea with the price of a gm nv4500 and the availability of small block zf5s around me of trying to mate a gm 454 to a small block ford zf5 and am wondering if somone out their makes the adapter plate to do this because I am coming to a dead end trying to find one. I do not want to do a sm465 because I want the overdrive. And I have built the motor to 450-500 hp so I don’t believe a nv3500 will hold up to it. Thanks in advance.

Do you have machine shop access?. Do you have skills? I can tell you how to make one. I've done similiar.But you'll need machine shop access and you'll need to be a good welder to make the flywheel.

Advanced Adapters would be my first call

I do have access to a nearby machine shop and I am a fairly solid welder and know some very good welders around me.

I adapted a V6 Buick to a 911 Porsche bellhousing. And merged the Porsche flywheel to the Buick crank. I started with a 3/4" aluminum plate big enough for the Buick bolt pattern. Place it on the mill,bore a hole that just fits the engine crank flange. Make transfer punches to screw into all the engine bolt and locating dowel locations. Slide your plate over the crank,using the crank as your index center. Tap each transfer punch location to mark your plate. You'll need to do the same to a Ford engine to get your Ford pattern,unless you are lucky like I was,the Porsche transmission had a round locating register inside it so I able to use the center hole and lathe to turn a step onto the plate that fit snug in the bellhousing and held the plate centered to transfer my transmission side holes. Use counter sunk hardware to hold the plate to the engine,tap holes to screw the transmission to. For the flywheel I cut the center out of the Porsche flywheel made a new center with the Buick bolt pattern,with an interference fit and chamfered edges on the pressure plate side. Heat the flywheel,freeze the center,put them together. Weld front and back. Thinking about it I had to use a Porsche flywheel,you may get lucky a 454 flywheel may fit in that bellhousing and pressure plate may work with Ford TO brg. IDK. Then you'd just use a Ford disc chevrolet pressure plate and flywheel.

What bout a Tremec TKO ot T56? If the F**D box was designed for a small block it probably would not stand up to a BBC, especially if its "built " ?
Alternatively a Gear Vendors unit on the back of the SM465 ?- that way you get both bullit-proof and economy ..

PS - NV3500's are fine if you don't "Dump" it.

And if you are I guess the F**D box would let go too ???
