compression is alitle high if you plan on adding much boost unless you go for E85,forged pistons and good rods are important if you plan on making power like most blown engines like to make. EFI is a nice feature but not realy nessesary. its mostly a question about how much power you are trying to make and how long you want it to last. not many blown smallblock mopars out there.




thats my blown smallblock thats not completed yet but well on its way.
