Oh I'm not gonna argue with you on that. If there is a fast N/A 4.6 chances are its not gonna be that streetable. Due to the lack of cubes, to make power you have to spin the motor. So high rpm and huge gearing don't equate to a street friendly vehicle. Cubes dominate the N/A scene. Plain and simple. But you have to give credit where its due. To run low 9's with less than 330 cubes is pretty impressive. -Mark
you're kidding right? ..... No i'm being sarcastic. geez.
But seriously for some reason i didn't think of the cammer motors when i was looking. I was looking for 2v 4.6's. There are a grip of fast Mach1's and a few Cobra's (n/a) just gotta look.

all of the single digit mod motor mustangs i've read about that have gone that fast in the 1/4 mile are stroked. just like the ls1's. i haven't seen a stock cube 346ci ls2/ls6 go 9's in the 1/4. all the n/a ones have been stroker motors. not saying it can't be done though.

There are quite a few of us on this site.
It is just shitty to see as there is no cylinder head from the aftermark to really help these motors out. The 2v stuff is complete junk and the 4v is mediocre. Once a better cylinder head will be released for these motors, you will continue to see turbo/blower applications running wild. Because if the head sucks... you just have to "push" that **** through with some help. Not to mention the larger side of a Ford mod motor barely crops over 331 cubic inches.
They have some new blocks that will help with that, but that still SUCKS.

i love how the mustang guys always throw the displacement card, when cobras are running a 4v per cylinder set up. If we had a 4v set up are heads would flow like crazy. So either way, we can bicker back and forth, 4.6s have something that ls1's dont and ls1's have something that the 4.6s dont. I think its somewhat of an even comparison.

??? Mustang owners pull that card because its a fact not because its an excuse! Lets compare your LS1 to the new LS7 and you would see there is just no comparison, cubes win N/A.

As for the Jason Steen comment from the other fella, I agree that he does good work but I have worked around some of the countries baddest cylinder head porters (One being the man who created the LS6 port for GM) and they all agree that the modular stuff FROM FORD, not some of the other companies out there, are junk. You can make them work but it takes a LOT of time AND money. Like always.
Hopefully they can get some help, because these cylinder heads for these LSX motors just kick ***.
if you build a 383 with your stock ls1 heads it wont make much power, the ls7 makes so much power because not only does it have cubes but it has the heads that flow enough to make 500 horsepwer, try a search and learn something about displacement, displacement is not horsepower gain, having heads and intake that flow enough to make power in bigger displacement equals horsepower.

https://ls1tech.com/forums/drag-racing-results/628613-quickest-stock-internals-list-11-79-bump.html these are just bolt-on cars, they have a few cam-only cars pushing low low 10s and heads and cam cars have made it into the 9s.
