I think first thing is to compare the world race block to the indy block. Although it doesn't change much in the strength factor it has some better options like bushed lifter bores and dual bell housing bolt patterns. Indy has a larger skirt and the fifth main is cross bolted.
Some peoples opinion may be the indy block is stronger but unless you were in the design room it's only speculation. Looks can be deceiving. Something like the quality of the block material can throw that theory out the window
Most will never run either block close to their limits

The only problem with Indy is the people at Indy .. I will stop there. as for the lifter bores being bushed thats just machine work. just look in that area.. The Indy wins hands down with some of the high spring Psi ran.. some are close to or over 1000 psi over the nose. the indy is stronger in that area. look at the front 1 cylinder side lifer bores ..As for the Dual bell pattern thats nice but most aftermarket cases come with a Mopar opt. again No biggie.. Look at the main webbing. All I did was post this to see what people have seen and there thoughts .. were not in on the Design..... were the end users.. BOB when I do buy another block.. its thru you .I can't deal with the Edit over at ---Y..

Unfortunetly most of the ones I've came across are already 4.50" I was hoping more would show up before I buy a new Iron World Block.

Here is a thought at what I see. The indy lifter bore area looks superior to the world but when you look underneath how the skirt area is so much larger than the world block, is all that material needed to keep the block from moving around?
All that material is in the valley area for a reason. .
If the lifter bore valley was a true problem than world would have made it beefier.

The tight skirt area is a concern with stock and after market blocks.This is an area that traps oil around the rotateing assembly and cause a lot of oil to be thrown on the cylinder walls and cam.This area is the cause of some of the loss of oil pressure at the big end.The Indy wide pan blocks allows the oil to migrate further away from the rotateing assembly and returning to the sump quicker.

We a constantly learning also,and are glad to pass on what we learn.As far as the blocks we get from Indy,they are quality and any changes we make are our decisions for our or our customers specific needs.As a end user or representative to the end user we are responsible for the products final state.We some times supply unfinished blocks to other builders.With that being said,since we don't live in a perfect world and crap is known to happen,we stand behind our work and Indy stands behind us on their product.What few and minor issues we have had in our almost ten year relationship has always been resolved satisfactorly and professionally.I don't see the issues of customer service that most complain of.From Carrie,Jim,Sam,Ken and Russ at Indy I can only say that they are friendly,curtious,helpful and professional in our busniess relationship.They meet our criteria of a great manufacture and supplier of products and BGR meets their criteria for a good customer,we use their products and pay our bills.I don't get any better than that.
