That’s a good question bc I like the idea of a 6 speed, especially after driving 30 miles each way on the highway to a car show. I have 3.73 and 5 gear at 70-75 I was wishing to drop into 6th lol. My longtubes bbk ceramic I got for a steal from a guy who bought them new, swapped To a t56 and couldn’t clear the housing. I snatched them for 200 bucks and he bought some new ones but he said they we for an automatic which gave him enough clearance. Idk what else he was running etc I was just happy to get the headers for such a deal lol.
