Hello All,

My cousin is currently building a 68 Pro-Street Couger.

I would guess he is about 60% completed.

He has basically spared no expense on this build up.

Me being a Chevy guy, and him being a Ford guy adds spice to our family relationship to say the least

He has built a 429 into a 521 stroker, Put an tunnel ran with dual carbs etc. etc.

The only thing is his block is a 2 bolt main.

Now I'm no Ford expert or no motor guru, but is this going to work?

I mean I think his 521 is supposed to be good for 800-850 hp.

What is the HP limit on a 2 bolt main 429 block?

And what is a good block to replace it with?

He is hard headed so if I say that many Ford Hot Rodders suggest this he might do it.
