It’s a good source for information, especially on the blocks. ARE engineering also has a lot of useful information. On the economy stroker kits, I hear that the Scat stuff has the best quality in the lower cost stuff. In the higher end stuff Molnar Technologies, K-1/Wiseco, JE/SRP, Callies & Compstar, Manley, Crower, etc. But with of all the stroker stuff out there, though, a big crank doesn’t always mean big power. Buy as much cylinder head as you can afford and build the rest of the engine around that. The TFS heads are very good. The people who have been there say that a 470-496 inch engine is the limit for the stock port window of a factory based head and larger builds favor a Max Wedge sized port. I have seen many racers with 451-470 inch engines that ran quicker than 496-500 plus engines because more available funds were put towards the cylinder heads. 451 or 470 can use a factory crank and stock type rods, the other build take aftermarket cranks and should really use aftermarket rods. But even a stroker with undersized heads is a load of fun in one of these cars, it’s like the torque of a black hole. There are some members here with some really impressive big block street cars. A stand out example is JohnnyDart’s early seventies Dart with a 470-400 tunnel ram. Gawd, I love this kind of build...
