Ive ran some smaller intakes on my 512. Streeter. It still ran like a bear. I went 10.95 with a ported six pack and 10.92 with a TM6 and a 4150/1050. I have a Indy single and a dominator on it currently and it feels stronger but, it’s gonna get the six pack when I put a 4 speed back in. The TM6 is surely one of my favorites for street duty.
