In my 85 C10 , I swapped 601 58cc to vortec 906 heads. They were milled to 60cc. 305 with a perfomer intake on both pre/ and vortec. My comparison would be no loss in pulling power at low rpm. The low end was the same, the mid band was a big difference.

A 305 , Q jet, performer cam, 3.73, 3000 stall, 28" tire. The basic foundation for a driven muscle car/truck.

To be current it is now supercharged, but before it was as stated.

Can you tow a tractor. I have towed as much trailer wieght as my class 3 hitch allowed, hundreds of miles.
