I'm hoping for a similar number, although I am aiming for 250-260 horsepower and 300-310 pound feet of torque, our of my 250.
The first thing I would recommend (and most people here) is to get a copy of Leo Santucci's Inline 6 power manual. I've read and re-read mine and it's a fantastic resource.
You should also read T. Lowe's dyno thread too.
My plan to get there is as follows:
250 block bored .60 over for 258 Cubic Inches
Knife edged crank
292 oil pan
Prepped stock rods
Forged pistons to increase compression ratio
Head work with bolt in lump ports (head milled?)
1.94 intake valves 1.60 Exhaust valves
Harland Sharp roller rockers
Cam (not sure about duration yet)
HEI ignition
Dual Webers with Clifford intake manifold
Headers
I'm sure there are details I am missing.
I do know that the stock block can accept nitrous and turbocharging is also an option. Was your engine rebuilt or did you just bolt on these parts?
