I have a 1959 Chevy Apache. I have the 250 c.i.d. block ready to install. My question is: what engine mounts do I need for the front and the rear to mount that 250 I6 motor? Do I use the same type that were on the 235? What is the best way to mount the front and rear. (Also, I have adapted a 700R4 Trans to the 250 motor). I'd appreciate some advice. Thanks.
