Default HP Estimate?

I am putting a 95 LT1 motor (caprice 9C1) into my 69 camaro and was wondering what kind of hp and tq numbers to expect. My setup will be:

Stock cast iron heads and 10.5:1 comp ratio
Full length headers
2 1/2 exhaust w/ Flowmaster 40 series (no CATs of course)
No air pump, EGR equipment, or A/C unit
GM 847 cam

Any ideas?

350-365ish depends how good your tuner is, with that big of a cam you might want to think about getting those heads slightly ported at least. Stock heads are going to be choking that big of a cam so maybe you should think about that.

Get Aluminum Heads, they are the ones with the 10.5:1 Compression. The Cast ones are actually 10:1 area, unless you have the thinner Head Gaskets.
