Nice. I’m not sure what work was involved but I was talking to a guy at Irwindale (RIP) and his dart was running 5.80s with a carbed gen3. He said he had 100 hours in the intake alone. It was clear by looking at it, it had been welded, ground, and epoxied heavily.
‘63GT on here can attest to the efficiency of the Prefix single plane on my heap. After he slightly rubbed on my BGE heads to flow 360+ he flowed the Prefix intake: ZERO air loss. 600 Hp with a stock short block, a cam and a carb-ed intake is cake
