bluevenom: I'm debateing about the desired power output. Either way I go I will seek around 6 hundred to the wheels. My fuel system is currently stock with the exception of the included HP parts (36#, 255 pump and adjustable fuel pressure regulator). I know that I can get this to work untill the 550 range, but plan on sumping the tank and upgradeing the pump and injectors as I go (injectors upgraded based on displacement and fuel needs). I plan on purchasing a tweecer or PMS in the future. Most of the planned mods would fit with either motor. My biggest hold up is the max capability of the 351 block. I would like to stay safely below my blocks capability.
First off,your going to need a pretty strong trans to handle that.Figuer out what you want to do there.
As for your fuel system,I dont think your 255lph pump will be able to keep up to 550rwhp (motor,maybe).I would go with something like an Aeromotive A1000,sumped liek you said would be the best,but you could use a drop-down pick-up too.Injectors would probably be in the 70lbs range.
The block really depends mostly on rpms....an early 351W block with arp studs and 1/3-1/2 filled (it will run fine on the street with a good alum radiator) could hold 900hp no problems if you keep the rpm below 7000rpm.Witch you would want to anyhow,being that the 3" mains dont exatly like to be spun that high.
The rest of the motor would probably be something like an Eagle or SCAT crank with SBC diameter rod journals with a 6.20 or 6.250 H-beam rod on dished pistons with standard ring size.You would probably end up somewere in the 9-9.8:1 range depending on dish,or OTS/custom piston design.
Of course that DART will ahndle what ever you can throw at it,but IMo why limit your-self to the smaller motor? Go with a DART IE block,9.5" deck,Cleveland main and just build it up while you run your current motor.
