Which block do I have and should I get?

[Blown04]

Hey guys,
Looking at getting a bare 4.6 block from Sean Hyland for about 350.00 bucks. I am going to fill it with a forged rotating assembly and all that, but i noticed that Sean Hyland sells two types...The Romeo and the Windsor. What is the difference between the two, and which block is it that i have? or how can i find out which one i have. Thanks for the help.

The main difference is the crank bolts. I think Romeo's have 6 and Windsor's have 8. You can also tell by how many bolts are on your valve covers. If they have 11 bolts its a Romeo and if it has 13 (I think) its a Windsor.

I just read something that most Windsor's were meant for truck engines and most Romeo's went for Stangs and the like..But there was some interchanged.

don't pay $350 for an iron block. the stock 4.6L block is capable of handling 1000rwhp straight from the factory. there is no reason to pay an outrages price for one.

when dss or vt build the whole short block for u, do they use a stock mustang engine and just forge all the internals, or do they use an iron block?

i was going to buy one so i can turn up the boost when its time, but i dont want heavy ass iron
