hey guys just wondering what yous reckon my car should make on the dyno?
ive finally got all my parts together now so in 3-4 weeks time it will be sent in to get put together:)

whats goin on.. pacemaker extractors with twin 2.5inch system with one resonator in each side, maffless tune, crane cam (hot) heavy duty valve springs, crow push rods, ARP head stud kit, crow cam chain with a crow adjustable cam gear and a full gates 25% uderdrive pully kit..

im thinkin it should make the 300rwkw mark but hopefully a little more:)

what sort of power do you guys think and also is the anything else i should be doin while its getting worked on?

cheers

Depends on the cam I guess... but it's fairly common for a LS1 to make 300rwkw with the modifications you have listed.

Just one thing... and I'm not sure on this... the intake manifold was upgraded at some point around the VT-VX LS1 era I beleive.

I'm pretty sure it was going from VT to VX... but someone will correct me on this.

Is it auto or manual? probably need to upgrade that area if you're around 300rwkw.

Other than that... some diff gears? give it a bit more "bite" off the line...?

Good luck

if its a cam with a fairly small lift aroun the .550 mark i would say 280-295kw which i say it might be because once you start going over the .615 you really should have valve relief in you pistons if you go to a cam with around that .615 plus you should see the 420+rwhp the other things you mentioned ie.push rods,timing chain and arp studs wont make you any more hp jut make it more reliable also shaving a fair bit off the heads like around the 40-45thou mark really makes a difference it sounded a bit much to me but i tried it and it payed off
