they work pretty well. you might see a tenth and a mph from switching. scavenging might look like a great deal on paper but like communism it falls short in the real world. now on a stroker i would go with anything with larger primaries, but i got my macs for 200 bucks and so far ive trapped 111mph with that and a hotcam with a tci ssf3800. first time out. ran a 12.4 with a 1.85 60' so its far from ideal

Do the midlengths only gain 5 hp over the stock manifolds? It seems like the long tubes are good for 17-22ish over the stockers, and everyone is gaining like 10-15 over the mid lengths...

I helped with the install, and he's right, for some reason the LT's were a lot easier to slide in and out compared to the mac's

I'd keep the MACs. You will only pick up around 5rwhp up top with LTs if you have done the collector mod and cleaned up the welds on the MACs. The LTs will make more TQ and mid-range, tho...
