My engine without the blower peak hp is at 6200

Post by oldhead »

My engine a SBC 400 without the blower peak hp is at 6200 with 470 HP. just where Comp cams said it would peak , The cam is a 248/260 114 cl. If it was a 302, would a rpm be higher where the peak is...Its 8.0 to 1 by the way Oldhead

The simple math is 400/302*6200= 8212rpm is about what you'd expect...hp would remain about 470, new torque = old Torque X 302/400. It won't be exactly those numbers but they would get you in the ball park.

Your guess pat on the back is wrong, Others are making 1500 hp with other SBC, I would like a answer to the question. Oldhead

the only question i see that you asked is, will the rpm peak be higher with the smaller displacement engine given the same cam, and the answer is yes. based on your last post, i think youre looking for something else, but thats the answer for what was asked.
