just to share:
my current bug.. has a 1600dp , pulled the heads, and working on it as a 1600sp stocker for cruising.. whilst i build sumthing "funner" LOL
super dirty workbench, bug in the background, helmets etc :P
:D la entrada unica :lol:
intake port, looking into number2 intake valve
intake port , looking into number 1 intake valve

chamber 1 looking into intake port
chamber 2 looking into intake port
closer shot of chamber 1 into intake port
exhaust port
still have to finish it up , do a 3 angle valvejob/cut and back cut the intake valves,
and a lil flycutting..
still woud be just a stock 1600sp.. just maybe it could add a lil pep to it.. |

The engine is apart right now. I'm upgrading to a 1835 turbo and going to use the heads on my girlfriends car.
I put about 20k miles on them and the car was an absolute screamer. Bone stock bottom end, 87mm forged mahle's, dual 34's and a lightened flywheel. Its putting out 70hp. I had this car past 110mph... who says single ports limit your top end. |

| Ive never done any single port stuff but it looks like theres a lot that can be done to them,and I bet they sound wicked with what would be a mild cam in a d/p motor. the D port is nice but I would widen it out a bunch & go 44x37 if possiable.I have always thought about doing a set for my brothers lawn mower/tractor,( we use it to move the boat,car trayler, just about everything,)I doubt we would see much if any preformance addvantage porting it. never know I might have an early bug one of these day to do it to just fro fun(as a spair motor) |

....great job on the heads should wake up your motor a lot what all you guys are doing with single port heads does not cost a lot of money and your haveing a great time doing it...thanks for the pictures great help spencerfvee ............................................................................. oquote="ralf"]just to share:

after i built my 1600 single port motor i must tell you the truth i was shocked it reved so high and still pulled the car to the et times i turnned i have just put on taller stacks put a 180 main jet in it sounds better goint to the track on friday to see if i can get the jetting right all you guys have got me pumped up to go faster i went to the shop today and guT a set of single ports heads cleanned up going to port them open up the intaKE SIDE BIGGER going to make a set of 36 mm intake valves AND a set of 34mm ex valves aND FLY CUT THE HEADS FOR 11.1 CR sorry about the caps i keep hitting the key lol i allso got a set of empi end castings going to port them i think they will flow better than the dds ones i dont want to weld the heads for bigger intake port i want to do things that any one can do i have a set of 1500 pistions and cyls lol what would a 1500 turn in the 1/4 lol good luck on your turbo motor they run great my friend ohio tom simpson runs a street car and races it with a turbo on it ..his best time with street times is 11.30 1/4 turbo are great for makeing hp spencerfvee............................................................... quote="Almost Alive"] spencerfvee wrote: hi great job love the heads you have good old JB weld we have all used it lol again great job thanks for the pictures how does the motor run ? spencerfvee

Get a singleport fix and enjoy some singleport racing on my youtube channel. 30 videos all singleport related, except for the 2 broken flexplate truck video's.

| update i am shocked that there are a lot of guys out there building single port motors and all the guys that posted pictures of how they ported there heads and the great info every one has offerd ..if any one has pictures of there motors please post them i am realy getting into the single port thing its does not cost a lot of money and it works great . any one that has pictures of differnt carb set ups for single port heads post them many thanks to every one who posted this is what sambas all about spencerfvee spencerfvee wrote: so you say single port motors wont run . read this i built a single port motor for drag raceing only ... i got tired of people here on samba saying a single port motor wont run ..or dont use single port heads .. i built this motor with what some would say is all the wrong parts for a drag race motor .and i am tired of hearing guys on samba say you cant make a single weber or del run well they allways say run dual carbs ... i used stock crank stock rods stock case 85.5 pistions engle 120 cam single port heads ported by me .. dual springs SS valves stock size... cut the heads for 10.1 cr 40 del carb single carb ... dds signle port end castings... i ran a gen and fan... headers stock fly wheel .. i put this in a drag car thats 1,500 lbs... took it to larrys vw show here in ohio this week end.... ran a best time of 9.41 at 69 mph 1/8 mile thats a 15.14 in the 1/4 mile i shifted at 7,000 rpm pulled the frount end up in the air when i left the line... you can have fun for under $1,000.00 in a motor ...i beat a lot of dual port motors . i ran pro class in have not gotten the motor jetting right yet... but i will... it will run faster needs more tunning. it was the first time out for this motor did not have the time before the race to dial it in ..jetting is not right yet i hagve 180 airs 188 mains dels like big main jets lol people would come over to look at my motor and shake there heads ...they could not belive it was a single port motor ..that ran that well my point is you can build a sigle port motor that will run well ... you can run a single port motor on the street maybe with a 110 engle cam 9.1 cr a del single 40 carb god a love del carbs ...they do the job well ...you can run a stock crank but i would not go over 5,000 rpm for the street .. a stock crank will last for drag raceing only... AT 7,000 RPM ...I HAD ONE THAT I RACED THAT WENT 5 YEARS BEFOR IT WENT BAD lol its been fun building a under dog motor next i am going to take it a part and put a set of 92s thick wall clys &pistions up the cr to 11to 1 take the 30mm venturis and run no venturis ( C Berg trick i learned ) yes dels will run with out venturis i have done it in the past and it works great for drag racing cheap way to get a bigger carb out of a 40 del lol spencerfvee |

I´m currently building a 2017ccm singleport with 37mm inlet- and 33mm exhaustvalves :D
I had to modify the heads a little bit, to make my speedwell manifolds fit.

i am blown away ..super job... just when i thought i saw evey thing .. your a god lol i cant tell but what did you use to form the intake ..it dont look like a welded head but my eyes fooling me lol and how much time do you have in the intake port ..would like to here how you did it ..did you use a milling machine ? to get it flate again great job thanks for shareing spencerfvee..............................................................

| thanks for info it was bugging me so i went throught my old books and found out that the 311 101 353 A heads have 20% bigger intake ports and flow better than the other heads there 1967 to 1970 heads so your right as long as they have 35mm intakes you got a good head spencerfvee..........

A friend of mine did the welding on the heads, he is a genius when it comes to welding on alloy :)
I did did the porting by myself, I think it took me a week or so to finish one head. Next up the holes for the spark will welded up and new holes will be drilled. I want to use the spark plugs with the smaller diameter :)
Then the heads will be machined to fit 90,5 barrels and the compression ratio will be raised to 9,5:1.
that`s the plan so far :D |

yeah i have noticed the 311 heads, being 35.5 intakes, i think so far has the better potential amongst other SP heads,
except ofcourse if you're workin on a 36hp then you got to work with what you got.. |

| I dont want to piss any body off, but I was wondering about that head that had all of the welding.witch was very nice. but if you were to put in 42x37 valves, unshroud the chambers to the size of the cylinders at the valves&add a swiril to them, then do all of that welding and weld it kinda deep so you could seperate the ports,make an intake that looks like it is just 1 tube but in fact 2 tubes then add the 2 bbl carb that looks like a 1 bbl (with opened venturies) mounted on each manifold. would it still be a single port??? or when welding it up add the center devider so it comes up to within .050 of the top of the head serfacecarb mounting flange but still use single port type manifolds. but now you canaim the charge at the valve much better for better flow,and it is still a single port but with revised runners that will use the inerta supercharging effect much better now. sorry but my brain is always running.it's a shame I cant catch it any more. |
