4.6

I was told that a 4.6 engine could handle over 1000 hp with the right crank, pistons, and rods. What year 4.6 can do this? Is it only the late model mustangs or can the early 90's 4.6 F-bodys do this also?

Thank you to all that reply!

Hmmm? 4.6 FoxBody. Must a been a special edition, LoL.

oops sorry I thought the cobras they made were 4.6...

Okay, here it goes, the SVT Cobras had the 5.0 until 1995. After 1995 (96 and up) they all had the 4.6, except for the 2000 Cobra R which sported a 5.4. There was a special Cobra R in 95 also that had a 5.8. The 4.6 was not introduced in the Mustang until 1996. F-body mustangs only existed until 93. So basically what I'm saying is there was no 4.6 Fox mustang, I have seen people though, who have stuffed the 4.6 engine in a fox body mustang. To answer your question yes, some 4.6 blocks can handle upwards of 1,000 horsepower. However early 90's F-body mustangs you mentioned had the 5.0 engine as I explained before, that block would probably snap in half with that kind of power. There was however an earlier version of the 4.6, that block was extremely strong. I believe it was made in Italy by Teksid. The 96-98 Cobra blocks as far as I know came from that block, it can handle 1500+ horsepower. In 2001 though, they started using a lighter block, the Windsor block, they added extra ribbing to make up for a weaker block. That block probably wouldn't be able to handle quadruple digits in horsepower. Perhaps the early 90s 4.6 blocks you were talking about were the ones found in the 1992 Crown Victoria. Those early 4.6 blocks were cast iron blocks, but unless I'm mistaken, they won't bolt up to the new transmissions. Now, I BELIEVE they've decided to go with Cast Iron blocks again. Sorry, very long post. Hope I've cleared things up a bit for you.

The GTs have all been on a cast iron block setup. The new Cobras are on a cast iron block setup as well (03-04). Something about a blower motor not being able to handle the whole 100,000 mile thing without problems with an aluminum block (similar to what the earlier Cobras had). Incidentally, the new GT has an all aluminum block, pumping in excess of 500+ hp. Its yet to be determined what the new Lightnings will have for a block; though I believe they're going to stick with the tried and true iron block setup.

From what I understand, a GT block will handle 1000+ hp with the right pistons, etc. But just doing that setup is expensive.

Wow! The 96-98 cobra blocks can handle 1500 hp!

Jesus...
