388 Questions
Building a motor for a 69 Chevy pick up weekend warrior street truck pump gas. 350 block bored .0060 over. It has flat tops 3 3/4 stroke. CR figures 9.8 to 1
I have heard that this block tends to run hot with a +60 bore. second question, will this engine require an over size oil pan? My 383 lost oil pressure at about 5000 rpm before I put an after market pan.

I've run .060" over blocks and as long as the cooling system is up to par, they've never ran any hotter than any other.
The stock pan will be fine as long as a standard volume oil pump is used.
