[427SnakeSC]

I have a 302 in my Classic Roadster S/C. Last year I put aluminum heads, a wilder roller cam and a bigger 750 Holley on it. It has an aluminum intake and Accel ignition. I have a 5 spd in it with a 4.11 final drive. I estimate it is putting out about 350 - 375 hp. I find it extremely quick and have yet to be beaten out of the lights. I took a 427 CSX out last year for a run and found it not to be any quicker than my SB. Saying that, though, I have ordered a new CSX, and will be running a Keith Craft 427 in it. The BB may not be any quicker than a SB, but they do have all that torque for sparking up the tires at will. Also, if "correctness" is an issue, then go BB. The SB runs cooler and just as quick and may handle a little better, although the 427 I took out last year didn't have any handling problems. A cast 427 with aluminum intake, heads, water pump, etc. will only weigh about 100 lbs more than a SB. Keith quoted me that it will be in the 625 hp and 600 lbs. of torque range. It all depends on what you are after. If "correctness", tire shredding torque, the sound and look of the BB are not on your wish list, go with the SB.
