Not worth the time and money. For starter you would require a CJ block with 4 bolt mains for strenght. Then you would have to match the "round" oil and water holes with the heads.
If you want a BOSS 429 HEMI block let me know. I also have a head and other parts.
Once you have a B9 block and heads, then it can be matched with other parts.

Re: 429 and 429 boss heads tranfer

Ive often dreamed of the same for my 429...but I thought the only real issue was the boss heads were dry decked- and Im not sure if the block and heads were grooved for the orings or just the heads...man that would sure look cool. two bolt w/iron crank would not live long if heads were "used to capacity" but I think in a mild street configuration it could be fine- although for bottomend/midrange the stock heads would probably work much better than the gigantic ported hemi.
The boss429 to me was the coolest 'looking' motor ever put out, except for maybe a sohc427...I'm probably gonna stick with Iron for a couple reasons, of course cost being a BIGGIE, but also the thought of losing a head gasket... iron on iron stands a lot better chance of lasting 'forever', but man are those heads heavy...
somewhere out there there are a few all magnesium can-am 494 inchers too-now that would rock!just imagine smallblock weight with mega Hp/torque...got an article I saved on the 'Tasca boss 429' that had one of these rare powerplants- one wicked Mustang...

Confidence: that feeling you have just before you realize the mess you've gotten yourself into...
