As usual hit another speed bump in my 383 build.
Have been quoted $750+ by two local machine shops for 030 overbore, freeze plugs, oil galley plugs etc etc.
That's about double of what I expected to have to spend.
I planned on my '74 2 bolt 030 overbore and a main stud girdle.
Here's the kicker; I can have a 4 bolt 383 block ready for assembly delivered to my door for $795.
Just days ago I found a 400 block, 2-bolt , 060 over bored but needs finishing machine work $450 delivered to my door. Needs final honing and plugs so $300.
They only sell 060 overbore so no option for 030 or 040.
They clean, check for cracks and overbore but no mention of remaining wall thickness.
According to their website they use these blocks for their own HP builds.
So here are my choices:
I'm leaning towards the 400 (413) even though the rotating assembly will be about $200 ($999) more then the 383. Aluminum heads will be $80 more with steam holes so app. $875/pair with SR cam springs.
So the money I need for the 700R4 is gone. Which means a couple of months delay.
Advise anybody?

So here are my choices:
- Stick with my '74 2 bolt and spend $750+, run it with main stud girdle
- Order the 4-bolt ready for assembly $750+
- Order the 2 bolt 400 w/060 overbore and run it with main stud girdle $750+
