datzenmike Posted February 22, 2012 Report Share Posted February 22, 2012 That's just a stock picture. I just noticed the manifold. Probably the 'Hyper Pack' option for marine applications. I think it was a 4 bbl.... Hell it says so right on the air filter!!! Includes a special cam too. Mine I made an adapter and ran a 318 2 bbl and split the exhaust into two and ran a second set of pipes. Sounded like hell with glass pack Walker Continentals but improved the 30 to 90 acceleration some. Talk about lean... the dizzy and oil filter were a bitch to get a.t Quote Link to comment
ggzilla Posted February 22, 2012 Report Share Posted February 22, 2012 Lean broke my distributor! At least I'll blame that. I couldn't see (because the engine leans over so far) that the cap wasn't put on fully and when I cranked the engine the rotor caught on the cap and the plastic gear on the distributor snapped right off. haha. But other than the manifolds cracking, the Slant 6s were tough and reliable. Here is my slant six, same color as your stock photo: P.S: My Datsun wasn't broke, didn't need work. Was just following the maintainence schedule, which means I worked on it regularly. Quote Link to comment
TENDRIL Posted February 22, 2012 Report Share Posted February 22, 2012 i heard that it leans for fule to mix into it better :unsure: Quote Link to comment

Was just following the maintainence schedule, which means I worked on it regularly. They are a tough motor. I was like 18 or so, burned the clutch out in 2 months. Eventually had to get help from my neighbor to re-ring it. That's when I put the big 2bbl on it. One night I was 30 miles from home and a rod started knocking.... nursed it all the way home. Piston/rod/crank later back on the road. Man I was hard on that car. Traded it in on a new '70 340 Dart. Quote Link to comment
Stupid_fast Posted February 22, 2012 Report Share Posted February 22, 2012 i heard that it leans for fule to mix into it better :unsure: Well, that's not exactly what I meant when I told you that. The L engines are designed to lean, and designed to have a downdraft carburetor, so the intake manifold is at an angle, so if your engine is straight your intake puts the carb at an angle. This means the carb isn't sitting straight up, I heard from Troy Ermish that it will make it run a bit better when its sitting at the correct angle. Quote Link to comment
Dime Dave Posted February 22, 2012 Report Share Posted February 22, 2012 How is this for lean, 1965 152CI IH Scout 4 cylinder (right half of a 304 V/8). Quote Link to comment
Z-train Posted February 22, 2012 Report Share Posted February 22, 2012 Pontiac had leaning 4 cylinder(half a 389) 4 years earlier. :P Quote Link to comment

datzenmike Posted February 22, 2012 Report Share Posted February 22, 2012 Slant six came out in '60 IIRC. They were aluminum but dropped because of cost in '61. Was the Pontiac 6 befor that? Quote Link to comment
Dime Dave Posted February 22, 2012 Report Share Posted February 22, 2012 The Chrysler slant 6 was introduced right around 1960. It was a CI pushrod engine that was used in about every vehicle they sold. It came in 225CI and 250CI versions (the latter used in trucks). I think it was used right up until the Omni was introduced in '78 I had a '74 Duster with a slant 6, 3 speed on the column and a non synchro 1st gear. A very fine peice of American engineering.

datsunaholic Posted February 22, 2012 Report Share Posted February 22, 2012 Slant 6 actually survived into the '80s. My folks old '83 B150 van had the 225 version. They wore it out twice in 180,000 miles. Not big enough for a 8-passenger van. Chrysler used the 225 until '87 in trucks. There wasn't a 250ci version. 170, 198, and 225, with several 225 variants.

Siempreloco Posted February 22, 2012 Report Share Posted February 22, 2012 http://www.youtube.com/watch?v=AwbxuL0jqps Gangsta Lean. Actually a good song, haha. Quote Link to comment
screamer510 Posted February 23, 2012 Report Share Posted February 23, 2012 Take your valve cover off and lay it on a flat surface and you can measure the angle. FWIW, I think the original ('50s) Merc 300SL Gullwings had their engine mounted at an angle around 30* off vertical to clear the hood I know early '60s Alfa Romeo TZ1-TZ3s had this too. Talk about an expensive intake manifold! Makes you wonder how those engineers make everything "fit" when they are designing cars, especially back in the days without computers! Quote Link to comment
bananahamuck Posted February 23, 2012 Report Share Posted February 23, 2012 Maybe the slant 6 had to lean that far to keep the carb out of on coming traffic.. Quote Link to comment
ggzilla Posted February 23, 2012 Report Share Posted February 23, 2012 The Pontiac slant engine was a four, 1/2 of a pontiac V8. So it was a 45-degree lean. And overweight as a consequence. Slant-6 came out in 1959 with the 1960 models. Used through the 1987 model year. The first ones were cast-iron. Quote Link to comment
TENDRIL Posted March 3, 2012 Report Share Posted March 3, 2012 so is there a direction someone can point me to get the proper motor mounts for the l20b into a 510 wagon? Quote Link to comment
albyneau Posted March 3, 2012 Report Share Posted March 3, 2012 Its lean injection Makes the fuel flow faster to the combustion chamber :huh: Quote Link to comment
albyneau Posted March 3, 2012 Report Share Posted March 3, 2012 You guys are all SO WRONG~! Do you know nothing of the ultimate conspriracy??? Those leaning engines emit electromagnetic waves that cause an imbalance in the earth's gravitational field. It's slowing the revolution, causing longer days~ and hence global warming. We are all destined to die, and that's when the aliens who fed us this self-destructive technology will come and take over our earth. Only v-8's can counter this phenomenon, restore that imbalance~ and save our planet! I saw it on HULU.... Quote Link to comment
