I have been thinking
I have a good 360 crank  some spare 390 rods the old skinny ones  rods....make a spare engine ( grocery getter)   NO Racing maybe try out some 351M pistons and cut my own valve reliefs
a low compression 8:1 352 with a decent quench.
Might be better to just leave it a 332 but use one of my light truck 360 crankshafts and regular timing covers
Junk the steel crankshaft and FT timing cover

we shall see
Thank you for the help

Good afternoon guys....i purchased a cheap 331 block  100 bucks..i wanted the street master intake that was on it and i need a set of good 390 rods.
it has the large beam rods..casting C6
Got he deep sump baffled pan and pickup
Bore is std 3.875
i though maybe i could use the block for  std 390 also
i cannot get a 1/4" Allen wrench between any cylinder..But i noticed the block was sleeved. They sleeves are approx .125 wall
would this be safe for a over bore to 4.050? or even 4"
how much overbore can i get out of a sleeved block ?
I can use the help
Thank you
