I am down to the frame on my '58 Apache. Eventually, she will have a 350 chevy with what I am thinking is a 3.73 posi rear and a 4 speed manual tranny. I am wondering if anyone has any comments on this setup, and if I need to box in any parts of the frame due to the added torque that the 350 will output. Also wondering if this setup will pull too many RPM's on the engine cruising down the highway in 4th? Looking to get a new rear end soon, so I can rebuild and fit it asap. Any suggestions are appreciated. Thanks!
