What power should this big cube setup make? Here are the details:
418ci w/ max ported LS6 heads, Cola crank, Eagle rods, diamond pistons, yella terra rockers, cam should be about 230/240, asp balancer
Bolt ons:
QTP 1 7/8 Headers w/ high velocity merge collectors, TSP 85mm Lid, SLP 85mm Maf, Katech Ported TB-epoxied, Speed Inc stage 3 trans, PY3600E, LS6 Intake manifold, NGK Tr-6, Optima Batt, MSD plug wires, MSD 50# injectors, Walbro 340 pump
I would like to know what would be good numbers for this setup or what it should make.
Thanks andy

Re: What power should this big cube setup make? I would think atleast 500 - 550 rwhp...... 
a little more info would be nice:
- stroke and bore
- compression ratio
- cam size (durration, life, and LSA)
- A4 or M6

Re: What power should this big cube setup make? stroke: 4in bore 4.08

A4 with stock rear

Re: What power should this big cube setup make? I don't think it will make over 500 on an auto. The cam should be more like a 242 or 244 with around .600 lift. Cola is out of the crank buisness so I assume you already have the crank. Is this on a iron block, and if so did you sonic test. I tested two iron blocks before finding the one that I went with, and even after the bore are offset for max wall thickness I will still be low 90's on two cylinders. Just a heads up though. That rear needs to be swapped. It will blow quick with that kind of torque unless you just use street tires.

Re: What power should this big cube setup make? My guess, with a cam in the mid 230's and under .600 lift, with 10.5 CR in an A4 is 465rwhp. I am sure you would be able to find a dyno somewhere that would give you 480rwhp though, especially if you lock the converter on the dyno.
