Beowulf Posted May 9, 2022 Report Share Posted May 9, 2022 Evening all. Been a while since I posted, still out here fighting my cancer. Anyway most body work is done and want to rebuild motor. Looking for recommendations on rebuild kits, and if any knowledge on Schneider cams.. Not race spec-cam, something close to factory if I need a new one. Anyway hope all are well, thanks for info.Greg 1 Quote Link to comment
datzenmike Posted May 9, 2022 Report Share Posted May 9, 2022 I don't know if there is a kit. You likely will have to find all the parts from different suppliers. Quote Link to comment

Stoffregen Motorsports Posted May 9, 2022 Report Share Posted May 9, 2022 (edited) Have you tried your local engine machine shop? They have access to parts that don't normally show up online. And, they know what works and what doesn't from experience. I think it's kind of like the meat industry. We never see the same quality of meats on the grocery store shelves as you can get in a restaurant. They may be labeled the same, but trust me, restaurant meat is always better.

No reason to assume you need a new cam and if replacing with something close to stock you may as well just find a good used one. Stock L20B is 0.413" lift and 248 duration however while lift is correct, it's doubtful if duration is measured at the universally accepted 0.050" valve lift that all after market cam suppliers use. Maybe someone knows. While talking cams it should be noted that today's oil formulas are about half the ZDDP levels of 40 years ago. ZDDP is a zinc additive that prevents scuffing of cam journals. Today's cars don't need it and it fucks up their catalytic converters. So one way to assure your levels are high enough is to switch to a racing oil or simply use Shell Rotella T4 or Chevron Delo 400 diesel oil. Quote Link to comment
Beowulf Posted May 9, 2022 Author Report Share Posted May 9, 2022 Going to machine shop tomorrow, keeps telling me he’s 6 months out. And I get the same answers at all the shops. Can’t do a drop off to get it in line as they don’t want to be tripping over it. Only like 3 shops in my area. At rate this is going I’ll be dead before I can get it done. 1 Quote Link to comment
Stoffregen Motorsports Posted May 10, 2022 Report Share Posted May 10, 2022 What I mean is that you can buy the parts at a machine shop. You don't necessarily have to have them do the work. I usually grease the shop guys to get my stuff done first, or maybe over the weekend. You'd be surprised how far a $100 bill can get you. 1 Quote Link to comment
paradime Posted May 10, 2022 Report Share Posted May 10, 2022 Hey Greg, To speed things up, California Datsun sells a Datsun 510 620 521 L16 L18 L20b 2.0 Overhaul Master Engine Rebuild Kit w Pistons for $800 https://www.californiadatsun.com/engine-overhaul/510-620-521-l16-l18-l20b-2-0-engine-overhaul-rebuild-master-kit.html Keep up the good fight bro. Take care of yourself and cheat in the race of what others say is inevitable. Quote Link to comment
banzai510(hainz) Posted May 11, 2022 Report Share Posted May 11, 2022 800 seems a bit much. I think one could pc this together for alot cheaper. but does show pistons in there. If all Japan made parts then I would justify the price more Quote Link to comment
datzenmike Posted May 11, 2022 Report Share Posted May 11, 2022 No mention of parts makers. Could all be Chinese. Probably convenient and ok for average rebuild but not if really serious. You could get better for less if you search and pick and choose. On top of $800 you still have machining the bores to oversize and what about the head? Quote Link to comment
Stoffregen Motorsports Posted May 11, 2022 Report Share Posted May 11, 2022 The last four cylinder head I paid to have a valve job done on cost about $300 to have done at a local machine shop. I wonder if the price has gone up, like everything else. Quote Link to comment
