So I’ve swapped my 512 back and forth. It’s a bit stronger with an Indy intake that’s MW ported (my heads are in between) with a 1050 than the six pack but I don’t think it’s a blow out. I’ve done quite a bit of work on my six intake throughout the last few years. I also run a 4412 center carb with the mechanical outboards (they have pumpers). It would make for a fun track day but, it’s hard to run the car cause it doesn’t have a bar and they get their panties in a bunch when it clicks off 10’s without one… lol
