my 250 is out of a 79 camaro.

The numbers coming from Clifford suggest a 25% improvement (Stage I) and you could get a 40% improvement (Stage II) with a 260-270 degree duration cam, performance distributor & coil, and mill head .060 or put higher compression (9 or 10 to 1) pistons. See www.cliffordperformance.com for details.

The Chiltons manual, if I remember correctly, put the 250 (pre-1975) at 155 hp. 25% improvement would be 194 hp and 40% would be 217 hp. Not big block territory but incredible torque and better than stock small blocks I think. (I said pre-1975 because I don't recall what the integral intake/head does for hp. You can't put a Clifford intake on an integral intake/head engine.)

You have to want the inline 6 to do this since it costs more and you end up with less than if you did the equivalent to a 350 or bigger. There is no substitute for cubic inches, but it is lots of fun to make people think you have a stock V8.

The 250 is a tough engine and gives years of trouble free performance. While not the original engine in my truck, I've put over 90K on it and it probably has about 200K total and I've only replaced the head about 10 years ago. Doesn't burn oil and still purrs (maybe I should say roars with those Dynomax additions).

Have fun with yours. 6 only equals 8 if you don't do anything to the 8. My 2 cents . . .
