As long as you know and aren’t kissed when it goes south.
I’ve never built a 383, but I’ve built a 417/421 setup, which is similar but more bore and stroke. Hydraulic roller unless you can handle a solid roller (they can be difficult.) NO angle plug heads - period.
I’m not trying to push you in a direction. You need to answer some questions : 1st - what block do you have? Is it a roller block or roller ready block? 2nd - do you have the skills to tune, EFI or carb? You need to be able to tune either and the tuning concepts are the same regardless of carb or EFI. 3rd - do have a trusted machine shop? 4th - do you understand that the heads, cam, headers and compression is where the power is made? The short block only has to be able to live at your desired power level.
I’m not pushing you into anything, but if you have zero experience with putting a motor together, then be clear that you will have some ‘learning experiences’ that cost you money.
Please answer the questions.
