I have an 1986 chevy 1/2 ton with a 6.2l diesel and am throwing a 383 crate motor in so question one : the 350 motor mounts will work right ? And question two : do I have to put new holes in the frame or is there existing hole if new holes are needed where can I find the measurements to do so?

Thanks for the help

 

Oh and another question I'm headers aswell and I have no idea what type of exhaust to run so if you know of load good sounding exhaust systems let me know. Please no glass packs or fart canons I want it to sound mean lol
Thanks
