What's the best engine for a Superformance? Easy. What's the best engine for ANY of these Cobra replica's...............427SO.
Can't get to the spark plugs on a 460 based engine, and (I may get in to trouble here....) a 351W is........well.......a SMALL block. They belong in the 289 cars (IMHO), and don't have the low end TQ you get in a BB that makes cruising around town simple.....and FUN. NOT to say that you can't have fun in a 351 car! I have many friends that own them and thay are PLENTY of fun. If you do go with the Windsor, I'd stroke it out to about 408 or maybe even 418 (or you can stroke it nowadays to 427 without too much fear, and then at least your badges will be correct!). You can get plenty of HP / TQ out of a well built stroker. I've got a buddy with a 408 in his SPF w/ 500HP. Like I said........PLENTY of fun!
Good call on the Superformance roller. Great car for the money. Mine is a couple years old now, and I've never had a problem with the chassis. Well built cars with a beautiful paint job. Back when I bought mine, it was between SPF and ERA. The ERA is also a beautiful car, but a little more $$$ (at least with the options I wanted) and a much longer wait. If I were looking today it would probable be between the same 2 companies and I would have to throw the new Shelby S. Africa car in there as well (just for the name, if nothing else). I heard they had some trouble getting things going, at first, but things seem to be smoother now. Supposed to be a good car for the $$$, although I have yet to see one in person. I guess it depends on how long you're willing to wait for your car. Spring is right around the corner, although that probably isn't a factor with you being from Texas. Being from Chicago, timing was a BIG factor for me when I ordered mine, and SPF delivered when promised. Great bunch of guys to work with as well. Treat you like family.
