The ports on b heads are already way oversized from the get-go, which is why they flow slower air below 5k and people love/need the gear so bad with them. Like mentioned, money is better spent elsewhere unless you're shooting for the moon and capable of doing it yourself without fn it up.
My parents used to have one they drove all over their oil lease property in oklahoma. Had it years. They had nothing but good things to say about it. A lot of fun to drive offroad apparently too. My mom really misses it.
Single disc from ProMotion Powertrain has served me well with a regular steel fw. Not as slippable as oem, but nothing like a light switch either. Great balance for a performance street machine. I had to do a few uphill, second gear starts to get the new clutch chatter out of it (per their...

37 as well. Remember seeing an oxford white Mach 1 on the showroom floor. Never thought I'd have one. Way too far out of reach it seemed like at the time. Graduated high school in 04 and had one 3 years later. Crazy how things turn out.
