What am I missing in this build? It's a 2002 Camaro SS. Want to have everything before getting down and dirty on the project. Car is a street only car.

Engine:

Block completely resleeved and machined by Steve Demirjian @ Race Engine Development using a complete Darton MID sleeve setup (Does more darton sleeves than anyone in the country, THE premier place for all Darton LS sleeves). Cost about $3000 alone to get the bare block ready.

I'm expecting in the 560-600rwhp range. I'm thinking I'm missing the following:

Flowmaster 4" merge for the Y Pipe
Dual 4" Electric cutouts (After the cats? Which type (QTP?))
New rear end (No idea what to go with)

So... suggestions? What am I missing? Sorry for the long post.

Thanks,
Daniel

 

ud pulley, stall

 

Stall will be 3400 rpm as suggested by David Yank (currently). UD pulley? 10% or 25% and do I really need one?

 

You dont need one but if your spending all that money it wont hurt. 25%

 

flexplate

 

maybe its just me but if you are going with the Mufflex with the magnaflow race muffler, are the cutouts necessary? its a straighthrough design, so you would be paying a couple hundred bucks for a minimal gain.

 

I really don't know what to expect from the magnaflow. Took a leap of faith on the muffler. I thought sound might be sweet to add some cutouts on it. Not looking for performance with the cutout portion.

 

if you are doing it for the sound aspect go for it, personally i wouldnt spend money on that with a 4 inch exhaust but go for it if you want to

 

and for the rear end do a ford 9" with 3.73s

 

moser, strange, m9, mwc?

 

moser 9"

 

i say Mid West Chassis Fab 9" with AT LEAST 410s spin that cam up nice n quick

i have 410s and am plannin on going at least 430s when i get my 9"

 

You'll like the Mufflex and the Magnaflow. That's what I have on my 454ci.
I also don't think you'll need a cutout.

BTW, Steve is the man for the Darton sleeves !
The local shop that finished up my block said Steve's machine work was top notch !
