SBC 408 Build

[micdeeznutz]

Thanks to the forum in advance, I was just wanting to know what type of hp/torque range I would be in with sbc 400 bored .40 over, 0 decked I think, splayed main caps, stock crank .10 mains/rods, dish pistons, 5.7" rods, double hump heads with 2.02/1.60 and ported and polished, should be around 10.5:1, comp cams 501/501 2500rpm range, hv oil, clevite bearings etc. Any commenst would be greatly appreciated as this is my first performance build, I guess, lol.

That combo should build some good HP. I had a slightly less agressive SBC 400 build that made somewhere between 300 -325 HP. Have you used any of the desktop dyno's for reference? They're fun to use but not always 100 percent accurate (garbage in / garbage out). This one may help

The power is in the heads. Why cut that setup short with old heads. New aluminum heads will make more power with the same setup and be much lighter.

Well, currently I'm on a budget and the double humps are all I have. I will be looking for some good heads later I suppose
