5.4 Block question.

[Kuro!]

Alright so Ive got a 5.4 block that I'm about to send off, and I'm wondering if anyone knows the most displacement I can get out of this block?

Just do the stock stroke and a cleanup bore. Unless you want to destroke it.

Destroke it to a 298 and rev to the moon?

Kuro, what gives? Different engine, or the one you just put in?

I bought two 5.4s, blew one up and now i'm pulling the blown one out and about im about to send it off to get built.

Assuming this other 5.4 works... In sha allah

 

[TexasBlownV8]

blew it up already? How'd you do that? nitrous?

Noooo....323". 3.750" stroke crank and rev it to the moon.

What rod & piston would this use?

Custom.

Custom.

Quick question, by doing this your just getting a better rod/stroke ratio correct? Or are you still better off going with a 3.700" bore block because of the smaller stroke of the 4.6 and the bigger bore un-shrouding the valves??

 

[US-1]

I'd rather use the big bore 4.6 based engine with a stock stroke.

I've seen the 330ci (5.4) block bored and stroked to 358ci

Sickkkkk, any chance you can link me?

Gotta have deep pockets for this one...

The "GT1000R", a 2009 GT500, made 1006 RWHP / 916 RWTQ on the dyno a few days ago. The dyno sheet can be seen below... over 800 RWTQ at 2,600 rpms!

I have too. Wasn't too impressive though. Even John Tymensky of Modular Performance has built several of them and he was "iffy" over the results.

 

[Kuro!]

Yea, well at this point we will have to see if the spare block is even useable...

A friend of mine has a built 5.4 . He competed in KOTS last year. Here is a link to his build thread hope this might help. http://www.horsepowerjunkies.com/forums/showthread.php?t=66321

Jesus what kind of intake manifold is that?

 

[camarokiller]
