350 to 455 conversion....what to do?

[BuickGSCali]

As of right now i own a 68 Buick GS-California 350. Im not really satisfied with the horsepower to dollar ratio. I have respect for the buick 350, but its hard to find parts. Not only that the parts are spendy. So im going to convert to the big block buick 455. Im do not really know what exactly i have to do to convert it. I know i have to do the motor mounts and the springs and that stuff........what else.....please help!

You need a big block fan shroud. They are taller than the 350 shroud.

You'll need a 455 fan shroud, (what smartin said) big block motor mounts, and you may need big block front springs. You can get motor mounts through any parts store, and a fan shroud off of a 70-76 electra will work just fine too. That should be all you need. -Kevin
