Are 1-bolt and 3-bolt camshafts directly interchangeable?

[Gustavo_383_Blower]

I am doing a swap on my Magnum (Brazilian variant of the Dart) to a Big Block B 383, which will also have a blower. However, I am having trouble finding supercharger performance camshafts for it, as the original is 1-bolt. Crower makes the part number models 32980 and 32981, but they only produce 3-bolt versions, not 1-bolt. Can I buy a 3-bolt camshaft and a 3-bolt timing gear set and adapt them normally or will need work on the engine block?

Should be a direct replacement.

B and RB only don't put a Hemi cam in a Big block.

Tried that once when I was about 16 or 17. Didn't work well. lol

You'll of course have to use the corresponding timing set, but yup. Bolt in swap.

1-bolt and 3-bolt timing sets are identical other than the number of attaching bolts.

A stock OEM 1-bolt works fine with the limited RPMs and spring pressures used.

Once you start getting heavy vale spring pressures and extended RPMs you use a 3-bolt because there's a good chance a single bolt will snap.
