[v8 ute]

Who makes the 4.155 stroke crank?

[VooDoo]

Very nice. Any Engine Dyno graph's?

BTW. Very nice spot Margaret River. Spent many drunken days/weeks around there in my misspent youth :D

[Hqcoupe350]

Thats a huge bitch!

Pretty small cam in there, could have easily gone 600hp with something a little more chunkier without it being a pig.

[plonkerchops]

where abouts in Margs are you Steve?
I just moved to Dunsborough from there last week. You dont own that nice gunmetal grey Monaro Coupe do you ???
I drove the Hyper yellow SS ute...........the one with the bloody loud exhaust on it ...you probably heard me morethan you saw me :lol: :p

edit: oops the gunmetal coupe cant be you ...thats a smallblock I think...

[NOS540HQ2DOOR]

It's a custom crank made by HTC in the USA

[NOS540HQ2DOOR]

I aiming for fat torque across the board. It made 420 lb-ft at 1600 rpm

[NOS540HQ2DOOR]

That me with the grey Q .It does have a big block in it but at the moment it has a 400 small block in it as i'm rebuilding the big block.

Some very impressive hardware and figures there :eek:

Who tuned it and will we see it at the plex ?

[Sonnymad]

wow very nice specs and results,same specs as my engine ,though i have a bigger cam :D

[Martin_D]

554hp out of 36lb injectors.........that MUST be on the engine dyno....as they wont get near supporting that at the wheels with 50psi fuel pressure
So, whats it got on the rollers 320rwkw?

[NOS540HQ2DOOR]

We are still testing and will be using bigger injectors.(it show up on the dyno that the injectors are to small) It hasn't been on the rollers just yet.Hoping to get 580 - 600 hp with tuning and small changes ie injectors , ls1 edit computer programming.

To get 600hp you will have to go a bigger cam.

im thinking about putting a ls1 in a vl calais will this crank and bores fit into a ls1 block as i have access to one to play with

[NOS540HQ2DOOR]

No you can not.You will need a C5-R Block to get 4.16 bore size.I think from memory the max you can get with a standard LS1 block is 4.065 bore with new oversize sleeves.The crank should fit but you will have to check all the clearances.You could use a 6.0L LS1 Truck block.

[r8ls1]

nice. that with ls6 int or F.A.st or other. ?

I think the max on ls1 is around the 4.125 mark

[Plan B]

Darton's new "Modular Integrated Deck" (MID) design provides for maximum bore size potential of 4.160!!!,

[NOS540HQ2DOOR]

It's got a port matched Holley/Weiand John Lingerfelter Signature Series LS6 manifold

[strife]

here is a link to a 455ci GTO that MTI just finished

519 rwhp and 527 rwtq. Stock numbers were 291 rwhp and 308 rwtq.
