Limitations of the standard Windsor block - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have read in the past that the Windsor block in the EFI Falcons are not suited to high horsepower applications and I was just wondering how much was too much as far as the block is concerned. I am currently looking for an EL XR8 which I plan to supercharge and then later down the track modify the car more heavily. I have noticed one XR8 here in WA that is using an SVO block on it's 500hp engine. Does anyone know how much these blocks cost? If you are interested here is the link to the incredible car:

That awsome peice is 550hp at the wheels by the looks of it (700ish hp at the flywheel)... No our blocks won't cop that kind if power. 500 engine hp is their quoted limit. You need to look at the sportsman block or the svo block (about $3000 new i think). I'm not sure about the f 150 blocks as i have one in my ute and would love to know if they any better.
The guys better connected with the U.S. may have some better price info for you.
One other thing i'd like to know is if the mustag vortec bracket on that ute would fit the AU as well?

Give Marks Workshop a call and they will be able to tell you if the bracket will fit the AU dude. Mark has a lot of time for anyone who needs help and his work can't be beaten here in WA.

i remember there was a mustang on mustang corral that was pushing something like 800hp or more on a stock block and it split right in half - the only thnig holding it together was the sump and intake manifold.

the bloke then went on to say he knew it would go oneday and already had an SVO block sitting in his shed, and was just finding the limitations of the stock block.

so yeah about 800 / 900hp

He didn't crack it he split it in half! WAY WAY WAY PAST IT's LIMIT! Must have been a sweet car though. Ford quote 500hp most find out the hard way that this is pretty acurate!

was in a 93 mustang coupe if memory serves me

Yup you did i was just a lil worried about the 800-900hp part no stock block will cop that for long.

There was a 302 windsor stroker 355ci (mexican block) pushig 550bhp n/a and with a 200bhp shot of nitrous it was pushig around 750bhp...the block only lasted around 40 1/4 mile passes until it split the mains. Now as a guide line they say that the 302's are good for 600bhp and 351's for 700bhp to 750bhp and people still tend to push the blocks way beyond their limits...now you can use the experts advice or you can find out the hard & expensive way.
