That BlownChevy Cali guy will do you right. HB pulleys are available in 3mm increments. Smallest you can get on a Vette HB is 81mm. I've heard you can fit a 78mm on a Gen5 Camaro HB. Pretty sure my Vette Heartbeat came with a 96mm.

That's a lot of air blowing through a 5.3L. You have square port heads on your 5.3?

Just as a point of reference, the Vette in my sig had an 81mm pulley. 10psi of boost. 664/612 at the wheels. Pretty wild ride if you were crazy enough to mat the throttle on the stock rear tires.

Nice Vette..... But yeah i'm as crazy as a shithouse rat and wanna screw with the Camaros ,Challangers and Musty Mules! Plus it's getting close to running out of fuel anyway so this will be my stopping point until I do my 6.2 swap it is a GEN V 5.3
