Once you get that donk in you'll be smiling :D

As I was very happy, just that I keep on finding things that are holding it back now such as fuel pumps, EEC's, etc.

What sort of a box are you planning on running as the BTR job wont beable to handle that no matter what you do to it :roll:

I still hav'nt got all the bugs out of mine yet, but I guess its all just a matter of time fiddling with it

But you are talking about much more power than 500hp@flywheel and roller blocks are as rare as hens teeth (still much stronger than a 5.0L) so you go looking for a 351W from around late 70's, reto fit roller lifters and there is talk about safe 1000hp+ from a well prepped engine, but like any "mass production" block, not all are equal.

Curious, I have never seen a picture of a 351W, early or late roller with a split down the middle, if you have the pictures, can you post them, I will add them to my collection.

Here is just one 5.0L block, it is a classic.

Check out the rest of the pictures of it.

Mind you, 500HP@flywheel is a lot of HP on the street.

With a failure like that, how do all the internals end up, reusable, which parts were ruined !
And what are the symptons that a crack has started ? Oil/water leak, water in oil ??

Low oil presure and overheating through loss of coolant..There is no way a mains girdle will help there!!!
