HRH Posted October 14, 2011 Report Share Posted October 14, 2011 Wait, is it a TALL L20b, or a SHORT L20b? They're different you know. Some won't fit. Better measure the block first. Quote Link to comment

HRH Posted October 14, 2011 Report Share Posted October 14, 2011 Temperature is a bitch. If you get the TALL L20b, it might pop the welds in the hood during heat expansion! Quote Link to comment
bananahamuck Posted October 14, 2011 Report Share Posted October 14, 2011 You might need to also sawzall the top of the cam cover and remove about 9/16" and then reweld top back on, if it`s the taller L20. I had mine done at a machine shop but it wasn`t cheap. Quote Link to comment
banzai510(hainz) Posted October 14, 2011 Report Share Posted October 14, 2011 use L16 oil pan and pick up tube L16 stamp stell mounts. use a 202mm flywheel so you can still usew the stock clutch and T/O bearing and sleeve. If a 225mm flywheels you need a Datsun 620 L20b setup.. as for tall short I never heard of this. use a short aircleaner if hits hood with a Weber DGV Quote Link to comment

If it is already in a 510 and you are swapping it into another 510 then take it out WITH the motor mounts on it. Because it's a truck motor it should have a 225mm flywheel/clutch and pressure plate on it so remove the collar off the clutch arm on the transmission and use it on your transmission. (replace the bearing with a new one but keep the collar that holds it) Now this info above assumes several things. Like You have a stock 4 speed. The 510 that the L20B is in now has a stock 4 speed The flywheel on the L20B has never been changed Don't listen to these characters... the L220B is only 20mm taller than an L16 and the stock L16 motor mount brackets should allow the motor to sit low enough for plenty of hood clearance..
