Farmer Joe Posted March 22, 2010 Report Share Posted March 22, 2010 assisted a friend of mine with getting his L22b running today. i like to call it an L22 since it aint a Z block. anyways, this motor is about 5 years old now. he built it back in high school for his 510, but needed a motor for his truck. now the truck has been sitting for about 2 years with this motor in it. its only got about 3 or 4 hours of run time on it. its a l20 block with a z22 crank. its 30 over with flattops. a87 head with a little port and polish. and a stage 3 isky cam. its got a stock intake and carb for the time being. just to get it runnin. hes got a set of SU, but hes leaning toward just a 32/36. im actually suprised that it ran with a stocker carb with the massive amount of cam its got lol its kinda dirty, but heres a couple pics of his datsuns... and heres a video... http://www.youtube.com/watch?v=JxEWVNGWgEw Quote Link to comment
MicroMachinery Posted March 22, 2010 Report Share Posted March 22, 2010 Awesome. Drop that thing into the 510 and he'll be all set :cool: Quote Link to comment
420n620 Posted March 22, 2010 Report Share Posted March 22, 2010 whats up with the slots in the 620 bed, is he interested in selling ? Quote Link to comment
datzenmike Posted March 22, 2010 Report Share Posted March 22, 2010 An L20B block with 0.030" over bore and Z22 crank would make a motor of 2,124cc. I was going to call BS on this combo but I see now that Z20E pistons, late Z22E rods and Z22 crank would work for this and also have the required flattop pistons! Nice. Quote Link to comment
HRH Posted March 22, 2010 Report Share Posted March 22, 2010 Nice, you'll like the extra stroke of the Z22 crank. May I make one suggestion. With all the mods mentioned, a 32/36 will be a piece of shit atop a banana split. You WILL need more carburetion. Dual SUs, dual Webers, splitter manifold to run one big sidedraft Weber, like a 44mm. Investigate your options, a 32/36 will run that motor, but not well. Quote Link to comment

Investigate your options, a 32/36 will run that motor, but not well. I was thinking that same thing also. I don't even think 38mm su's will run it well but better than the 32/36. I would consider either Z su's or dual sides like mikuni or weber Quote Link to comment
Farmer Joe Posted March 22, 2010 Author Report Share Posted March 22, 2010 yeah ive explained to him that the carburation is gonna need some better addressing. this little motor moves alot of air now. im sure hell get it all figured out. its just cool to see this motor run after he built it 5 years back.

datsunfish Posted March 23, 2010 Report Share Posted March 23, 2010 That sounds pretty lumpy in the video.. Not sure of the specs on the isky stage 3 but must be like a .470 or 480. That would require competition springs. Just trying to get an idea what it has. Perfect candidate for some twin mikuni or weber sidedrafts with chrome stacks!. Why build a hot motor and not top it off. :D Su's would be cool too but maybe not cool enough.. Quote Link to comment
