hippieswithguns Posted March 25, 2014 Report Share Posted March 25, 2014 I have a 74 610SW with a L20b engine in it. My question to the community is will a L16 engine bolt up to my existing tranny??? Quote Link to comment
hippieswithguns Posted March 25, 2014 Author Report Share Posted March 25, 2014 i want to rebuild my L20b an just get around with the L16 for now, in case everyone is wondering.......LoL 1 Quote Link to comment
MicroMachinery Posted March 25, 2014 Report Share Posted March 25, 2014 It will, but it's gonna feel puny until the L20b goes back in. 1 Quote Link to comment
datzenmike Posted March 25, 2014 Report Share Posted March 25, 2014 It will if the L16 has a flywheel on it, the L20B wheel won't fit. Likewise if an automatic you will need an L16 or L18 flex plate. The L16 exhaust manifold won't bolt to the L20B down pipe. Quote Link to comment
MicroMachinery Posted March 25, 2014 Report Share Posted March 25, 2014 However, the L20b exhaust manifold WILL bolt to the L16(as long as it's a square port manifold; if not, it will still bolt up, but you MAY experience some leaks). It will have a bit lower, but that's not an issue unless you're pretty low already. You'll also need the throwout bearing and collar to match the L16 pressure plate; you won't be able to use the L20b clutch and pressure plate on the L16 flywheel. Quote Link to comment
datsunaholic Posted March 25, 2014 Report Share Posted March 25, 2014 Why wouldn't he be able to use the 610 (L20B 200mm) clutch and pressure plate on a L16 (200mm) flywheel? They're exactly the same pressure plate bolt pattern. If it were a truck, then the 225mm clutch/pressure plate would be a problem, but this isn't a truck... Quote Link to comment
MicroMachinery Posted March 25, 2014 Report Share Posted March 25, 2014 I was unaware that that was a possibility. Huh.. learn something new every day. :) Quote Link to comment
datzenmike Posted March 25, 2014 Report Share Posted March 25, 2014 The 610's L20B should have the square exhaust ports as they all used the U67 head. The L20B exhaust manifold will certainly bolt to the L16 head... but it's the set up where the intake and exhaust are bolted together. You can just bolt the cover plate down over the hole , I just don't know if it will clear the bottom of the separate L16 intake. They are bolted together and this plate is sandwiched between them. That's the hole in the bottom of the intake and the two barrels for the carb. Not saying it won't work. Measure the clearance between the L20B exhaust and the underside of the L16 intake. May work.

hippieswithguns Posted March 25, 2014 Author Report Share Posted March 25, 2014 thanks for all the help Quote Link to comment
Rhapakatui Posted March 25, 2014 Report Share Posted March 25, 2014 Haha... I knew there would be a flood of info soon. I just wanted to be first and not say anything incorrect. Thus my lack of elaboration. Quote Link to comment
KlassicMotion Posted March 25, 2014 Report Share Posted March 25, 2014 What about the oil pans? Are they the same between both engines? If not, you may have to swap pans and oil pick-up tubes until you're finished building the L20B. Quote Link to comment
datzenmike Posted March 26, 2014 Report Share Posted March 26, 2014 If the L16 is from a 521 or the early 620 definitely not. If from the 510... maybe, as it was also a car. Best bet is to use the L20B pan... that definitely fits the 610. Quote Link to comment
hippieswithguns Posted November 5, 2015 Author Report Share Posted November 5, 2015 well after a year and a half i am re starting my project.... L16 into a 610 wagon, so far so good..... 1 Quote Link to comment

INDY510 Posted November 5, 2015 Report Share Posted November 5, 2015 I heard the 510 oil pan will fit a 610, but not the other way around ..... good luck and post some pics of the 610!! Quote Link to comment
hippieswithguns Posted November 7, 2015 Author Report Share Posted November 7, 2015 So I ran into a quik fix/issue today on my build. I bolted a L16 down into a 610 wagon that originally came with a L20b engine. Only then did i realize that I forgot to measure the distance between the holes on the ring gear, I checked the the thickness and the diameter of each gear but didnt remember to check if the holes matched up, DUMBASS!!!!!! Anyway, I crawled under and went to put in my torque converter bolts only to realize that the holes on the original torqu converter dont match the L16 Ring gear, the housings on the trannys are the same but the holes on the torque converter are at 9 in. and the L16 Ring gear holes are at 81/2 in. ( L20b Ring Gear have 6 bolt pattern where the L16 has 5) So the quik fix, I found a socket to fit the center hole of the two ring gears, pinned them so they wouldnt move and made a template line on the L16 gear. I then carefully cleaned the holes up with a corse file drill bit. No slop what so ever........ so far I have only ran into needing a couple things off the original engine....... Here are a couple parts from the L20b that we needed for the swap to actully work: Oil Pan Engine starter plate Engine mounts ( of course) Exhuast manifold Any suggestions for my build are greatly appreciated!!

datzenmike Posted November 7, 2015 Report Share Posted November 7, 2015 So what you're saying is the 4 torque converter mount bolts are 8 1/2" (apart? or from the center? or what??) on the L16 and 9" on the L20B? Would really like to know what you measured. The bolts don't align the torque converter, just hold it on. Quote Link to comment
hippieswithguns Posted November 7, 2015 Author Report Share Posted November 7, 2015 I do know what I measured and I made it fit just fine... I even had a tranny guy look it over before i modified the gear..... it went together like it was made that way, LoL Again... the L16 gear is 81/2 in. across from hole to hole., and the Torque converter from the 610 wagon that originally bolted to a L20b is 9in. across from hole to hole (center to center of course) I had to drill out the extra to make the gear fit the 9in distance Both tansmissions have the same bolt pattern to the engine. I just had to swap the plate Do you have info on these trannys?? First came out of a 1971 510 SW L16 Second is from a 1974 610 wagon L20b Quote Link to comment
datzenmike Posted November 7, 2015 Report Share Posted November 7, 2015 I'm asking what the 8 1/2" and 9" were measurements to??? Obviously the holes aren't 9" or 8 1/2" so they must be the distances between the holes? or what??? The flex plate on the left is from an L20B. Can you show where you measured the 9"?
