"its actauly a common problem with the factory block it has very little re-inforcements and weak webbing most motors u see this happen to are well over 500hp and reving past 6k, it usauly happens after a hard run it starts with a light lifter tick and if not caught in time it ends up like this one, a v based engine is getting forces from all directions trying to yank it itself apart, when hp is up there and high reving it adds to the problem. they make all kinds of different girldles but they just delay the inevitable. the only real cure is a after market block, this is why a inline engine stay together so well, but like they say u gotta pay to play. Any car with over 500hp is gonna tend to break something. just do a web search and type in broken 302 block and see what ya find"
That was his expl. anyway!!
By the way i have looked at your page and all i have to say is.......
. That has to be one the cleanest, well put together FI'd foxes i've seen. I'm very impressed and if i had the cash to do a set up like that. At the drop of a hat i would. Very cool stuff bro

Very cool stuff bro This is old news, the blocks are weak, everybody knows that, 500 rwhp, they are done. Some last longer than others. I know of two that have split around here in the last couple months. One was making over 600 rwhp with a forged 347 and a girdle, one was making around 450 rwhp on the stock bottom end but ran into some bad detonation, that and before he bought the car, it had a blower on it but was removed before he bought the car. Then he put an SQ Trim on it.

This is all new to me, I was aware that the 5.0 liter blocks were practically indestructable. My roomates friend used to know a racer who ran a 300 wet shot of NOS on his stock 5.0. He said it was running low 10s. Those pictures are very shocking.

Nah, you have the 302 block confused with the 1,000+ hp capable 4.6 modular block.
Wow, I suggest you read on turbomustangs.com or the corral some and see that they are known to be WEAK. Some people get away with some stuff but ALOT dont. It's basically a known fact that if you buy a Mustang and wanna make over 500 rwhp, your block is probably on borrowed time.
There is good reading on the stock block chronicles on www.turbomustangs.com
The 5.0 is a TOUGH engine and will take alot of abuse but shear power will overcome the joke of a block. You can beat on them at over 200000 miles without a problem but trying to make 500 rwhp or more just dosent go over too well with the block.

I have seen a few of those cobras but not riden in one yet. I was thinking about swapping a 03 CObra motor into my mustang II and adding some NOS. I heard those blowers are really loud, kinda turns me on.
Gonna be $$$$$$$ to do a swap, www.modularfox.com has some good info on modular engine swaps. I have ridden in a Kenne Bell 04 Cobra, felt pretty good to me.
