Look What You Can Get For $2,000-$2,500
With common sense planning and execution, look at how much power your small-block can produce for under $2,500. These are three dyno pulls that demonstrate how much power you can make and why.

Pull 1 demonstrates what our 302 can do with the modest build-up we have just performed. This is with an aggressive flat-tappet camshaft and 302 heads. Expect 285-300 hp with 350 lb-ft of torque. With carburetor and ignition tuning, you can make the most of these numbers.

PULL 1
RPM HP TORQUE
2,000 127 333
2,500 162 340
3,000 198 347
3,500 234 351
4,000 264 347
4,500 284 332
5,000 285 300
5,500 273 261
6,000 244 214
6,500 213 172

In Pull 2, we've opted for 351W heads with stock valve sizing. these cylinder head castings won't cost any more, and we expect a solid 300-plus horsepower, with 350-plus lb-ft of torque. for just a few bucks more, go with a 650-cfm Holley and a roller cam for eye-opening numbers.

4,000 268 352

5,000 298 313
5,500 290 277
6,000 263 321
6,500 234 189

Pull 3 takes the 351W head further with larger 1.94/1.60-inch valve sizing. Check it out--327 hp and 367 lb-ft of torque. Again, we suggest a more aggressive roller cam, larger Holley, and deep-breathing headers for substantial gains in power. Expect 350-plus horsepower and 375 lb-ft.
