cylinder block

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

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

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?

Built 4.6L Short blocks run from $2199 up to $4999. A bulit 5.4L short block starts at $3799 up to $6499. 5.0L Stroker Short blocks start at $2899 and go up to $3699.

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

Got a link? I need a forged shortblock.

i don't know if this will help for a link but this shop is in California they are forged blocks

blockzilla

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.
