upgrading to a 429-will it fit

I am currently restoring a 69 coupe that has a 289 installed which was an upgrade from the original 6 cylinder by a previous owner. I came across a 429 big block and tranny that I was considering to install and aside from requiring the heaver front coil springs, the main question I have is will the 429 engine fit into the current engine compartment with the originial shock towers or did Ford install narrower shock towers from the factory to fit an OEM big block beast. I have heard of people "shaving" the towers but did not want to get into that considering that the body is already in the paint shop.
Any input would be a great help.

Thanks:shrug:

it'll fit, tightly, but it fits. You'll want some swap headers, and you'll need patience when changing spark plugs.

Just to say it before someone else does, you can stroke a 351W to 427, fits great, and requires no conversion parts. Plus it will weigh alot less.
