GM Performance LS3 or Builder?

[jlwdvm]

I can't decide on which way to go with my motor purchase. I want a turn-key setup and have looked at Scroggins/Jegs 525 hp crate motor that would run around $10K with motor, wiring, and oil pan. Other venders (I've looked at Texas Speed), can get a turn key set up with forged internals (I think) for $11-12K. The car is a 69 Firebird that will see track time on a 3.6 mile road course mainly and street time. I guess the main question is if the GM crate motor is going to handle what I throw at it and if the built LS2 is a little overkill. Any input would be great. Also trying to figure out which 5/6 speed, rear end, and fuel tank to go with.

I'd go with a forged internals one.
Get a T56 Magnum, Moser full floater, and an Aeromotive tank with their Stealth kit in it.
Just my recommendations :)
P.s I can source all of this for you, as well as a nice serpentine drive, etc :)

I would contact Schwartz Performance, above, they have some killer stuff out there and great people to work with.

I guess a large part of my question is do I need/worth the extra expense to get forged internals, etc for what I want to do with the car-motor? Keeping in mind that I still need to purchase a trans, rear end, gas tank, etc.

With forged internals you can rev higher, build for more HP, raise the compression, etc. For a track car it's worth the expense.
