Has anyone done any speed work on an L134? I can find a header but am looking for an intake?
Non-existent, unless you want to pay more for the intake than you probably did for the Jeep. They're rare as hen's teeth, just like the aluminum hi-po heads that were made in very small quantities 50+ years ago.
"Hot rod" and "Willys 134" = oxymoron-either version. Nope, I have never seen an aftermarket high flow intake but a die grinder might make some improvement. That said, a 134 ci motor with a max rpm of 4000 will not be needing that much more air. We haven't heard much from Lifesgoodhere and his juiced f head of late, but suspect he will know if one was ever manufactured.
there was someone on here that made an intake for his flathead...cant remember who it was..also,,were the supersonic heads the aluminum ones/..or something different?
I was looking to make a tubular intake for my L-head a coupla years ago but I nevr got down to doing it. A buddy made some flanges for me but that's as far as it got. Once the old manifold setup was out of the way I planned to use a cleaned-up F-head exhaust manifold.
I was going to use either a Weber progressive 2bbl or a pair of Solexes. The Weber would be a better choice, but I like the old-timey hot-rod look of the two-carb setup.
actually a hot rod L 134 would be a F 134.......
Doesn't the L134 have 2 intake ports, that each feed two cylinders? The straightforward approach would be to make a manifold for a 2V side-draft carb. A Weber DCOE is the obvious choice, but wildly expensive. A pair of motorcycle carbs (Mikunis?) would be another option, maybe dual Solexs or even a SU would work.
If I really wanted to put some effort into this, I'd research old hot rod books re how to hop up flatheads. I think there's a lot you can do with a die grinder to make them breathe better... though they will always be restrictive (that's why OHV and OHC took over all markets).
Then there's always boost...
This pic was taken from the passenger seat of my brother's F Head Jeep. This is the best performance upgrade we've found for it yet...
That's another reason why I haven't put much effort into this project. As for the sidedraft carbs, if you look at a stock L-head in a flatfender you'll see that there isn't very much space between the fenderwell and the exhaust manifold. That, along with my less-than-memorable experience with the sidedraft carbs on my MG Midget led me to look elsewhere...
Yer just jealous Patrick, that's all! R)
tsk tsk Patrick R)
Why is he pulling you backward?
I'm Glad that this thread popped up. My next project is going to require an L head + alotta mods (to the engine). Sorry, top secret. R)
Let me now what type of mods you are looking at.
I'll PM you when I start working on it.
I have a 52 M38 that has a cj motor in it. It is still 24v but I want to hot rod up the motor, and rebuild an MC motor for later. The Cj motor is too fresh to toss out, so I want to make it different. Clifford makes an exhust header. I am looking for a cam, head and intake.
About the only source out there for an L-head cam is Clifford, the same folks who make the header. Aside from the uber-rare Willy-Willy aluminum head you might go with a Kaiser Supersonic head and mill it down a bit. That's realy about all the options that are out there for the old L-head.
