283/350 swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Guys,
Just a little fyi for any doing a 238 to 350 swap. There's always a pulley question or two. Just installed a 350 in my 66 C10 this weekend. I'm using a short shaft H20 pump with two belt pulley's and a driver side mounted Alt. Noted a 1/4" misalignment between the pump pulley and Harmonic pulley. I've seen questions about this alignment before but never a good answer.
I found threw Vic Hubbard a Moroso shim kit that worked PERFECTLY. Added shims between Harmonic and crank pulley.... Nice. Kit allows up a 5/16" shim if needed.
Anyway, Just some info for any of you interested.
Cheers!
