Really the only bad part for this project in my experance are the
cast pistons I've done several with 3/8 rods and cast crank as its rpm's that kill them not boost (with in reason )
T R W and speed pro had a piston that was very cheap for blowers in std,30,,60,over and I swapped them for the cast piston for next to nothing ,and they even have reverse deflector
domes !! They were turbo pistons I think ,no big deal they don't care blower or turbo ,,their cheap !!
Then you will have a reasonable 5 to 6 lbs blower motor cheap
use a 280 comp flat tappet cam on a 114 ,andput some extra clerance on the wrist pins
From here you can go as mild or wild as you want this is a good starter motor
The 330 with cast is tough to do with cast pistons I agree

you guys are killin me here.
i know the 330 hp motor is not the ideal motor to put procharger on. i've know a few people who have run 5 lbs w/ an innercoler and haven't had any problems. i've got an EGT gauge and plan on checking the plugs on a regular basis. all i want to know is what plugs other people have run on similar applications so i don't run them to hot.
thanks.
