413 build help




I've disassembled my 413 and am preparing to take it to Muscle Motors in
Lansing to have them clean, Magnaflux and sonic check the block and heads.

Assuming the block checks out, here's my preliminary plan for the machine
work I'll ask them to price:

Bore the block .030 over using a deck plate
Zero deck the block
Line hone the mains
Bushing the lifter bores
Enlarge the oil pickup to 1/2"
Ream the main bearing oil passageways to 17/64"

Am I missing anything obvious?

As far as the heads go, if my existing heads are okay I will probably just
go with those for now due to budgetary constraints. All the stuff I've read
thus far suggests that you shouldn't scrimp on the short block.  I'm pretty
sure I will need to get custom pistons made - I want lightweight
pistons/rods but I haven't found any source for 413 .030 pistons except for
the stock cast ones.

I'm trying to not get too excited about this until I'm sure the block is
sound and can take the .030 overbore.  If it can take enough to get into the
426 size pistons, should I consider that option?

Thanks again for everyone's help and encouragement!
