I am buying a cam today and was wondering if anyone with an engine simulation program could run my combo through it so I can know a ballpark figure for my horsepower and torque output.

The engine consists of:
355 sbc w/ roller cam
speed pro flat top pistons, 10.1:1 compression
canfield heads, 195 cc intake runners, 2.055 intake, 1.60 exhaust valves, flow 260 cfm intake, 190 cfm exhaust at .500 lift
1.6 roller rockers
LT1 intake
speed density computer
slp 1 3/4" shorty headers, 2 1/2" true duals with magnaflow mufflers

The cam I am looking at buying is the comp cams 503. Duration at .050" lift is 224, exhaust 230. Intake lift with 1.6 rockers, .535, exhaust lift .544.

Thanks to anyone that can help me.

Edit: Does anyone know where the cheapest place is to buy this cam?

 

Give me a few minutes and I will work some numbers up...

 

Perfect timing My drive with the program crashed, I can't get it to read. I will have to reload the program later. I will get back to you...

 

Swapped some parts, now I am back in business! I ran the numbers through, this is a rough ballpark estimate. According to the simulation the combination above should make around 400hp and 470 ftlbs torque at the flywheel which given a rough 15 percent loss for the driveline, should work out somewhere around 340hp and 400ft lbs torque at the rear wheels. It is just a rough estimate, but it looks like a good combination

 

Thanks alot man! That sounds like a lot of torque for a 350. I didn't get around to ordering the cam yesterday so I am going to do it today.
Is there any way you can run a different cam through your program?
If so, the duration at .050" is 230 intake, 236 exhaust, .575 intake lift, .570 exhaust. 113* lobe separation. Thanks again.
