The reason I asked about the cam.. It was in a 70 Barracuda with a stock bore 318 with 340 X heads. The ports were untouched with about .060 or so cut from the chamber side. They were 63-65 cc if I remember correctly. I ran the 6 pack and big hooker super comp headers. It was a dog on the low end, but when it hit the 3200-3500 range to 6500 it really surprised lots of mustangs and camaros back in the day. I ran a hemi four speed with the low first gear and a 3.23 rear. It hooked good..I still have the car and the motor. I thought about using the cam and 6 pack on my 69 dart.
