cylinder block

[Blue_demon]

how much power can it take????

thanks

it's not the block it self. It's the internal i.e crankshaft, rods and pistons those need to be changed to forged internals

 

[Blue_demon]

that I know, a forged bottom end will hold more power, but I'm talking about the block, like to 5.0 stock block it can hold probably up the 500 rwhp and probably split apart ( don't quote me on this not 100% sure), and after that is best to upgrade to a dart block....how much can the 4.6 block can handle...

thanks

The Cobra guys are pushing some high numbers. I have read about some 800hp ones.

 

[Modular2v]

im pretty sure the modular blocks are good up to 900hp

In one of the past issues of MM & FF, they had a 1000hp Turbo Mach 1. MMR here in Oxnard, CA has a 1500hp 5.4L DOHC Turbo Mustang.

Great Scott! What would one do with 1500 HP? Send Marty back to the future?

All those block are remade or created to make that type of power.
The Teskid (96-98 Aluminun Block) is claimed to handle up to 1500. I dont know about the Iron's

for a daily driver mm&ff did a project stang on the 4.6 they managed 540whp from the stock block with forged internals (it's a long article theres like 3 or 4 parts to it) then they ordered a 5.0 stroker from CHP and they got over 620whp with more boost from the supercharger and got the heads worked form patriot performance not bad for a 2V motor that's a daily driver

there is are two fundamental differences between the 302 and 4.6 block. deep skirt and crossbolting. the factory mexican 302 block was good for 550hp for a limited time. crossbolting mains ties the block skirt to the main caps on a 4.6/5.4 block. There are plenty of examples of high mileage 600 hp 4.6l. I haven't heard of many main webs pulling out like 302 factory's. If I ever go to REAL hp then the cobra 6bolt block w/maincap girdle is for me.
