Then they are 9.4s cause that's where I know they came from

Either way still need a tuner that knows holly carbs and or rotaries

You might want to get a hold of Corky Bell of Bell Engineering. He's the God Father of making blow through turbo systems for rotary's. He's been a around since before anyone in America knew of HKS if that says anything. He was the founder of CarTech Turbo Systems. Back in the day (1987 ish) he released a 465 hp dual down draft ( weber ) turbo kit for 1st gen!

Outside of that you might want to talk to AK Miller in Pico Rivera, CA IF they are still around! They too have made many custom blow through carb kits!

I take it your running a 650 double pumper? It's a good carb for blow through application.

Good luck!
