3.2L S/S dyno'd 240hp at the wheels

To answer the original question pretty much spec for spec. Hope this helps.

I thought my build was conservative and was surprised at the outcome. I know others have bigger numbers, but I was only hoping for 250hp at the crank.

Specs 3.2S/S:
PMO 46mm carbs (running a little rich with 38mm vents)
J/E 98mm 9.5:1 pistons
DC40-106 cams (thanks John these rock!)
Single plug with non-recurved SC distributor (at about 15 degs intial to get 33-35 fully advanced, need to send in for recurve...)
Big port SC heads (stock)
MSD Ignition
L/W alum pressure plate (stock steel flywheel)
Stock valve springs/retainers (I know...)
Early smaller 1 1/2" headers, dual in/out M&K R-type muffler

Wish I could scan the sheet, but here is the basics (dyno dynamics dyno?):
239 rwhp (280+ at the crank depending on your math, dyno guy said about 300hp) HP peaks at 6500-6900 rpm (perfect, wanted a 7k redline)smooth curve all the way up

200-205 rw torque peaks from 4500-5800 rpm (240 or so at the crank?)
Torque is above 175 at the wheels (or 200+ at the crank) from 3500 - 7000 rpm Plenty of torque starting at under 3k to move a 2200 lb RS Clone.

I haven't gotten the smile off my face yet.
