Question about the 487X heads. I bought my 72 custom deluxe with a bad motor(I was told it had a rod out). I put a motor I had lying around in with vortecs on it. Anyway,I came across a deal on a 383 that I couldn't pass up. It is a shortblock only,I want to put it in my 79 K10. It has a THIRSTY 400 that is worn out,also has fulltime which doesn't help matters. I checked the heads on the motor last night and they are 487Xs,I was thinkin about using them on the 383. It is not a race motor,I was thinkin about vortecs again but with 64cc heads the c/r would be 10.3-1,alittle to high. What do you guys think?
