Does anyone know where to find a larger diameter crank pulley for LT1's?

 

Depends on wich size you have? Think ATI has 6.45" and 7.65" for LT1 engines.

 

I know for a fact that ATI offers a 7.65 8-rib pulley and a 8.5 12-rib pulley. Your best bet may be to contact ASP. www.aspracing.com

 

Where can you find these ati pulleys? do they replace the stocker?

 

You can buy the ATI pulleys straight from ATI. You will still have to run a balancer in conjunction with the crank pulley. Are you referring to blower crank pulley or balancer? I am a little confused on your question.

 

My blower uses the stock crank pulley/balacer so i need something that would replace it only larger.

It could be a piggyback style like a underdrive

 

Oh ok I got you now.

I am not sure if any of the aftermarket balancers are larger in diameter than the stock one.

If you want to run an crank pulley specifically for your blower then you are going to have to run a spacer on your blower so everything lines up.

I know ATI (not Procharger ) makes aftermarket balancers.

Companies like ASP can custom make a crank pulley to your specification.

 

humm.. Called asp today.. they will cut me one for $225. I've got to figure otu what size i want though.

Anyone have forsure measurements on the stock crank pulley diameter?

I think i'm giong to pully this thing up to 14pounds.

I'm thinking about making a custom chain drive for it.. that will be sweet

 

Wouldn't changing the blower pulley be easier than changing the crank pulley??

 

stock lightning is 9lbs at 2.93

i just got a 2.7 but its only supposed to give you +2.5 lbs
