  1. Doug, where did you find that "blue " page above? I think your right about 46, just want to hear it from someone who has done it before for a double check.
  2. I'm not a newb to Jason Grey's info, been into Datsun's for 20years, in fact my 72 510 has a long rod 2.1L that I built from his write up. Just that I never came across anything that told me exactly how many links between cam sprocket mark and crankshaft mark at top dead center on this conversion since block is 3/4 " taller than L20B and cam sets at a different height also with this head. I want a number so I can double check my setup, you know one link off and you have retarded it or advanced it. I used the Z24 front cover, very small amount of aluminum welding needed. I used ARP head bolts from L20B, ground off the engine ID projection to clear header, by the way IWIS W0133-1641757 is a good substitute for the MB timing chain link. Bad Doctor Doug, does that blue page you posted have a link? I think the cracked bolt hole think has been oversold on Z24 blocks, lots of them still running over on 720 site and my 720 Z24 with cam and supercharger ( yes, supercharger) is still strong after 66K from a rebuild. I suspect overtorquing the headbolts, 55-60 ft lbs isn't much. Anyway anyone know how many links exactly? 71 Z L3.0 74 720 4X4 72 full on rally car 2.1 long rod L20B 71 510 2dr Buick V8 project garage full of shit
  3. I was hoping someone who has been down this road can help. I,m finishing up my Z24 with SS l20B head and 44 sided drafts but I know it need to add four links to a L20B timing chain but how many links between cam sprocket mark and the crank sprocket mark at top dead center, same as L20? Also, how are people measuring the number of links on a chain, I get more than the books say. Roger
  4. Your right. 8/79-6/80 720 4x4 longbeds had 4.625 front diffs, try to find one. King cab 4x4's with 4.375's are easily sourced in Pick-a-Part, at least in AZ. Roger

    Why, you ask? Because I have a Z24 roots blower and I want to put it on my 510 long rod L2.1 So has anyone done this, sounds possible since L20B heads will fit Z24 blocks but what about cam sprockets? I don't have a Z24 head to look at right now. Roger
