383 Block - Questions

kythri said
So, found a possible block.

Date code tells me that it's a March 29, 1968, which is good, but some questions:

Cam in the engine has the following specs:

Cam specs--- intake Exhausted
Adv due. 292. 300
Dur @ .050: 242 248
Valve lift .549 .544

Lobe sep: 110.0

Engine was built for drag racing and is bored 60 over.

Another source tells me that since it's 60 over, if I ever want to rebuild, I'll have to sleeve it, because it's bored to it's maximum?

If I'm looking for a 383 for street use, not drag racing, am I wanting to stay away from this particular block?

geeze, you'll have that block for so long that when you finally need to rebuild it the whole damn thing will be worn out. so buy it, it has all the parts you need for a good motor and it'll be way less expensive then purchasing all new parts. put new rings, bearings in it and a valve job and be happy. when ever I build a motor I use the stock bore or go straight to .060" over for the extra inches and compression. what's the point in the .030" over thing unless you're building some ultra high rpm motor like moper may be talking about. my opinion others will vary as they have done already.
