]2eDeYe Posted September 8, 2015 Report Share Posted September 8, 2015 Yeah that's an annoying bolt to lose. If you know the exact length you could possibly source one on mcmaster.com they ship with a quickness. 2 Quote Link to comment
hobospyder Posted September 9, 2015 Report Share Posted September 9, 2015 which l motor is it loren? i have an l20b torn apart in the shop i can do measurements on, and i can possibly lose the oil pump gear if it's the same as the one on a z22 edit: status says l20b, let me know if that oil pump gear is interchangeable, i'll get to looking for that bolt when i get back down to the shop 2 Quote Link to comment
banzai510(hainz) Posted September 9, 2015 Report Share Posted September 9, 2015 I see the head dont have the water passage holes. Most L16s in 510 and 521 run the water line to the manifold to heat it so the carb dont freeze. If running sidedrafts carbs then waht you have is perfect and dont leak. if you live in a warm climate this is OK also and just plug the L hose by the fuel pump and not waterline is needed. The oil spindals and bolts are EZ to come by. I have tons of them 2 Quote Link to comment
Loren O Posted September 9, 2015 Author Report Share Posted September 9, 2015 this truck will be running SU's from a Z, on a manifold made for me by Z therapy. Steve saved my ass there! I bought the carbs from a friend from Facebook. we have talked so much about this truck, that I assumed he knew what I was using the carbs for. He assumed I knew what I was buying,& that they had come off a Z. Luckily for me, the Z manifold, etc were parts that Z therapy wanted, & they had what I needed to make the carbs work on my L20b. 1 Quote Link to comment

Loren O Posted September 9, 2015 Author Report Share Posted September 9, 2015 I'm not sure why I didn't notice it was the wrong manifold for my FOUR CYLINDER. I guess I was just too excited about finding a set of SU's that I could actually afford,& I needed a carburetor for this truck, so I jumped on the deal. oops! THANK YOU to Steve & Bruce at Z therapy for fixing my mistake! 1 Quote Link to comment
bilzbobaggins Posted September 10, 2015 Report Share Posted September 10, 2015 So they are building you a custom manifold or selling you a used one? My 220 su manifold has been ported and I need a unmolested one. Great thread by the way 1 Quote Link to comment
Loren O Posted September 10, 2015 Author Report Share Posted September 10, 2015 I think they're modifying one to work with those carbs. and thank you! sometimes I think this thread drags along without enough activity, much like the project itself. ah well, what can I do? 1 Quote Link to comment
banzai510(hainz) Posted September 10, 2015 Report Share Posted September 10, 2015 I would just bolt a stock manifold on the and a cheap weber down draft to get this going first 1 Quote Link to comment
Loren O Posted November 28, 2015 Author Report Share Posted November 28, 2015 I need to find a manifold gasket for this head. Will any square port manifold gasket work. if someone has a part number, that would help. the engine is supposed to have come out of a '78 620, but I don't know for sure that this was the original head. any help would be greatly appreciated. 2 Quote Link to comment

banzai510(hainz) Posted November 28, 2015 Report Share Posted November 28, 2015 510 intake gasket is the one to get and will be the same for all square ports . Felpro works common part buy 2 , 3 for spares and a valve cover gasket also fuck front cover set spare also remember you don't have the holes n the head to warm the carb if using the stock manifold. This head be good for Mikunis later as you wont have water leaks 2 Quote Link to comment
Loren O Posted November 28, 2015 Author Report Share Posted November 28, 2015 Thank you ! I am going to be running the SU's pictured above, using a manifold that Z therapy made for me. I still need to get air cleaners, and a choke cable. 1 Quote Link to comment
banzai510(hainz) Posted November 30, 2015 Report Share Posted November 30, 2015 I would run it with the stock carb or weber first as its ez to bolt up to get car running first and broke in. to have a set of SUs ready to go that mean you got one off a recent running car otherwise it might no idle off the bat or needs tunning up first 1 Quote Link to comment
Loren O Posted January 26, 2016 Author Report Share Posted January 26, 2016 Time for an update! Shawn Drawdy & I made some progress on my truck yesterday. My rebuilt L20b is in it's home I'm the engine bay! I'm pretty happy about this news,since it has been difficult for me to make time to go work on it,these last couple of months. Due to the damage to both transmissions that I was planning on swapping into this truck,we have decided to run with the factory 4 speed,at least until I can find another transmission, or repair one of the other 2 that I already have. We also have decided to start with just the 2" lowering blocks for the rear at first, then see how the truck looks after re-indexing the torsion bars. I can always swap in the 720 4x4 leafs later ,if I decide it needs to sit lower. I am going for more of a 70's mini muscle truck look,so I want the back to sit a little higher than the front. I may eventually go with wider rear wheels,once I find some that match the front ones,& a pair of rear "Fontana " style fender flares. 1 Quote Link to comment
Loren O Posted January 26, 2016 Author Report Share Posted January 26, 2016 I'm going to put these side pipes on my truck. 1 Quote Link to comment

banzai510(hainz) Posted January 26, 2016 Report Share Posted January 26, 2016 you prime the oil pump? since you head has not water ports you got to plug the up spout on the water inlet where the lower radiator hose comes from. motor looks good 1 Quote Link to comment
Lockleaf Posted January 26, 2016 Report Share Posted January 26, 2016 Nearly there. Very cool 1 Quote Link to comment

One question.. in the last picture to me it looks like the motor is tilted to the passenger side a bit much like maybe the mounts are backwards..??? Idk just looks like it to me.. I haven't had a L in my truck a while so I could wrong haha 1 Quote Link to comment
Loren O Posted January 27, 2016 Author Report Share Posted January 27, 2016 You know,I wondered about that too. I just went back & looked at some pictures of my truck,before we pulled the old engine, it seems to sit at a similar angle. 1 Quote Link to comment
uberkevin Posted January 27, 2016 Report Share Posted January 27, 2016 Hmm. I guess I just thought I remembered the exhaust being flatter then that. But if that's how it was.. haha must be right. 1 Quote Link to comment
banzai510(hainz) Posted January 27, 2016 Report Share Posted January 27, 2016 clean up that engine bay while you had the motor out motor is leaning correctly so mounts are fine. get new battery cable and the engine degreaser 2 Quote Link to comment
Loren O Posted January 27, 2016 Author Report Share Posted January 27, 2016 Yeah,I probably should have done that. Shawn is going to be doing some rust repair on that flat shelf like area,directly above the pedal assembly. I will clean up the rest of the engine bay when he's done with that. I need to get this truck moving under it's own power asap though. 2 Quote Link to comment
