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.

I would definitely sonic test the block. JMO

depending on the block number .060 over can be a lil weak on a stock block, also depending on the clock number u may need a deep pan, #880 needs a deep pan but 010 and 547 dont

Please explain

my last 385 was a 547 block and i didnt need a deep pan i used a stock one, my buddies 383 is an 010 and he ran a stock pan, but my new 383 is an 880 and i had the get a 6 quart tht was clearenced

I think he was asking if he needed extra oil pan capacity to prevent loss of oil pressure at higher rpm's. ..not weather or not the pan would clear the crank.

aaahhhh i see lol my mistake

I've had crank, rod, piston, pan, clearence issues in the past.

Angry parts, wanted out!!

LOL, yeah I had that problem also... and they got their way too!
