so, finally i made it, my dream come true and i finished the new engien for my hebmüller.

the plan was to buld an vintagelooking engine, nearly :wink: :beer: period correct but with some hard modifications inside.

some parts i collected:
*356 crank (lightened, balanced, regrounded)
*356 rods (lightened, balanced, new bushings)
*356 cylinders and pistons (82,5)
*356 super 90 rockers
*rebuild 36hp case (linebored, sandseal modification)
*wolfsburgwest Okrasakit (was for me the best decicion to modify thes things, not original suff)
*356 flywheel (lightened, 200mm clutch)
*oilsump (modified to fit on a 36hp case)
*26mm schadek oilpump
*fram setup
*Oilcoolinglines
*383 dizzy with flat cap
*starcoil, OT pulley

the enginecase got it's treatment, also the heads (welding, bigger valves, modified ports, and the main thing, modification of the rockerarmsetup with porsche parts)

the last things i searched for have been the carbs, a set of Solex 40pbic from a Porsche 1500super (2pc case). i got a set final, and after a hard rebuild the look really good on my also modified okrasa manifolds. i also have flipped the mechanic of the linkage, becaus the trottle bodys open inverse to the original okrasa setup.

so following are some pictures and final the video's

--------> machining the case 


modification of the heads:





--------> machining the heads 

--------> some stupid shit after grinding :lol:  

the rod's prepolished and balanced:




some enginestuff:








manifold modification




carb puzzle :lol: :roll:




some valvecovers with eastereggs :lol: :shock:






and the time came some days ago when i installed the engine:






last modification: aircleaners to fit under the heb decklid... (i'm not he fan of hammering the lid or installing empi eybrows for bigger airfilters :lol: [-x :lol: )

and finally on the easterweekend the engine got it first start.... (i changed several times my undewear before i was able to start this engine :shock: :lol: )


--------> finally it runns well :d  



so know i need my rims to drive it, but they are still at the welder :? :cry: :cry:

---

Wow! Damn!! Can´t wait to see how it runs.:beer: 😎

Whats happening to your wheels to need welding?

---

me too James :lol:

after the fact that i used my spare rims and 2 painted ones for the heb (only for the feature in HO'09 i tock my chromed set from my 57) i was forced to do the chrometreatement on an further set....








and now the are at backwelding the centers... he has prommised to shipp it this week and i hope i get it until friday :-)

thanks andreas, i hope it will run long enough :wink:

Great looking and sounding motor - nice work 🙂

---

...and finaly on the dyno after 3500kms...

sure, carb setting could make some minimal improvement to get the 90ps, but it runss great and i will not change anything at the moment...

Sorry ,you are way ahead.Maybe some gearbox mods with tall gearing for the new power.

Sell it to me!!:lol:

---

Nah Rob, you are too stingy!!!:evil:

:twisted: ET

Andi, lets go to the Santa Pod raceway and try to beat me! :lol: :lol: :lol:
Great work men!

[-x 😳 😳 not for sale :d it's MY driver 😛 :beer: :lol:




yes pascal, wich gear should i lock :?: :lol: :beer:
thanks :beer:




yes indeed a good idia, but i try a search and get zerro result :shock: :evil: on that topic. any input or idea??

---

What gearbox do you have at the moment ? my knowledge of early porsche boxes is limited but a final drive of 4.12 works well with that kind of power .If you just want to cruise at speed a high final drive is good but i prefer better acceleration .I believe early porsche boxes have closer ratios as well.I am thinking the porcshe forum on the samba is the place to be for this stuff as i have only ever used VW boxes.

i drive the standard crashbox none synchro @ all gears.... i want to keep it, i like the shifting and handling.. but an longer 4.gear would be very helpfull 🙂

---

Its a long shot but could you remachine a late model mainshaft to fit a split case box ?ring gear would also need swapping but it would give you taller gearing on all four cogs
