Estimating HP and Torque

[djsy934]

Need help estimating HP and Torque with my build so I can order a Torque Converter with the correct stall for my 4L80E.
Also advice on which Torque Converter would be awesome, do I need a $1,200 Circle D Stage 1B or is that overkill? Truck will be 90% street driven with occasional trips to the drag strip.

Here is my build so far:

Stock SyTy block .030 over (parallel decked and balanced 2 bolt main)
Stock Crank
L2441 Pistons
Eagle H-Beam rods
55 lb low impedance injectors (Siemens 3102)
412 Comp Cam
Comp Cams 7608 Push Rods
L35 Port and Polished Heads
Crane 11-1.5 Roller Rockers
Comp Cams 850-12 roller lifters
Arp Head and Rockers Studs
Cometic Head Gaskets
BBK 58mm Throttle Body
Ported Intake (upper and lower)
Ported Stock Exhaust Manifolds
Precision 46mm wastegate

Turbo:

P Trim .82 ar turbine housing t04e compressor housing with 360 thrust 60mm 60lb/min

Thanks

Re: Estimating HP and Torque

Obviously their are a lot of factors (tune, boost, air flow of your heads, etc) in how much potential hp your combo could make. I could see something in 550hp range with about 700ft-lbs on good gas (crank hp).

Spend the money on a Circle D....well worth it.

With that cam and 2 bolt mains I would not go that high at all.

That cam will limit you greatly IMO.

425.

Buy a good convertor once, or a cheap one followed by a good one later.
