Could someone do a software dyno to this engine components for me please?
Hi,
As I mentioned in a previous post, I'll start building a new BB engine soon, my goals are simple, a streetable engine with smooth enough idle and a good mid range torque, and something between 450-500 HP in the crank. Here are the components I intend to get :
1- A 2 bolts main block (14015445).
2- Trick Flow Power-Oval heads with 113 cc chambers :
Intake Runner Volume (cc): 280cc
Exhaust Runner Volume (cc): 137cc
3- Eagle balanced rotating assembly with 14cc domed pistons.
4- Hydraulic roller cam and lifters from Comp. Cams :
Intake Duration at 050 inch Lift: 218
Exhaust Duration at 050 inch Lift: 224
Duration at 050 inch Lift: 218 int./224 exh.
Advertised Intake Duration: 270
Advertised Exhaust Duration: 278
Advertised Duration: 270 int./278 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.510 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.510 in.
Valve Lift with Factory Rocker Arm Ratio: 0.510 int./0.510 exh. lift
Lobe Separation (degrees): 112
Intake Valve Lash: 0.000 in.
Exhaust Valve Lash: 0.000 in.
Grind Number: XM270HR
5- .041 head gaskets.
Do you think I would get a good streetable performance out of this engine recipe? can someone help me to do a computer generated dyno graph?
TIA

Usually this request is answered in Tech section, but other info needed to give you more accuracy are:
1. Cubic inches (bore x stroke)
2. Compression ratio
3. Induction (carb size, intended intake manifold)
4. Exhaust ( headers?)

I guessed so. Could any of the moderators move that post to the tech. section please?
and to answer your questions :
1- 467 cu. in. (4.310 * 4.00)
2- I am guessing about 9.5-10:1
3- Stock cast iron intake of the LS5 and stock LS5 Qjet carb.
4- Stock cast iron ex. manifolds.

With the info you gave me, here goes.....
(Using stock induction and exhaust severly limits your horsepower....adding more carb, headers, and better intake drastically increases power.)
