any cast piston guys using nitrous?

You should be fine with a 100 shot on a cast piston. So long as you are getting the correct fuel, and timing is good. I would suggest closing the plug gap to .035 but a stock heat range should be fine. Any more juice I'd step down the plugs..

im using 3924's right now, was going to use 3923's? i also have full msd on the car.

ok, after hours of googling ive come up with this , some thunderbirds had HO motors in them with forged pistons some did not, but it is unclear whether the non HO motor had cast OR lightweight hypereutectic pistons, im stumped, hopefully in the morning someone can shed some more light on this subject .

Mike said they were cast, and then he said he assembled the motor.

That being said I'd go with them being cast.

nope, hope to soon though.

I ran a 125 shot on cast pistons for years. Just make sure timing/plugs/fuel is right and you will be ok. When I installed a dedicated fuel system for the nitrous I stepped it up to a 150 shot and went another few years.. This was all on a chevy 350..

The 3924 will be fine. That is a step colder heat range then stock.

Open pill super power shot solenoids. Do it.

My dad is running a 125 shot on BBC cast pistons. Runs just fine.

Steve should start thinking about it.
