Enlarging PRP doesn't always help

My concern with laying back the SS too much is the loss of torque. I'm sure you've seen Darin Morgan talk about a tall SS being good for torque and a low SS being good for HP. Would the SS be designed different for a street car than a race car? In general the answer would be yes, but the SBM heads don't play by the same rules as some of Morgan's stuff.

Remember my wording when it comes to short side. I lower then shape the short side. A lay back on a piss poor short side like the Edelbrock is a small radius. Now if we were playing with a W2 head or a Chevy Dart Platinum head we are talking another story. Both have beautiful short sides.
