Interested to hear what combinations people have used that have worked well for them.
I am interested mainly in the 1600 to 1776 cc bracket and a bit more on the wilder than milder side.
Love to hear about it.

Two of my engines that have been well behaved are:

1776cc with mild grind cam, all balanced, standard valves with 3 angle valve job, twin 36idf carbs, extractors. Went very nicely.

1641cc with similar except twin 36 dcnf carbs.

Now I'm keen to go the next step with a motor round this size.

:party

lol... [size=6]1916[/size]

And for those that don't want to?
Surely someone has done something with a 1776?

The benefit of a 1776 is it doesnt need an engineers certificate. It comes with in the 15% capacity increase.

My 1776 was 040 heads, AP2 cam, dual IDF 36's - similar to your set up

Personally i think the 36's were better suited for a 1600. I wouldnt use them again.

Would love a set of 044's and a better cam

So - for the next step
1776
IDF 40's with 34 chokes
044 heads
Berg 308 cam??
CR around 8:1
1.4:1 rockers
propper exhaust - no heater boxes

That said i now have a 1916 on a stock carb.
No power house but a crap load of low torque down low compared to a 1600

For a daily it is beautiful and no duals to worry about

I like the sound of your next step blue74l!

That is the kind of motor I want to build.
The budget remains manageable and performance should be reasonable. thanx

Anyone with other thoughts?
What specific cam to use with the ration rockers?

Stay with a mild cam
:vader:vader

I have a very nice setup,that has good low range torque, while also having good power

1776
w100 cam
std heads, but with a GOOD port and polish, 3 angle valve grind
fully balance std crank, rods, etc.
heavy singel valve springs
twin 40mm dells
cromool;y push rods
std rockers (strengthened, ie no wavy washer)
009
8.9:1 cr
extractors

spins to over 6k (limited to 5300 rpm)
but bends valves as 8k (found out the hard way,with and over rev on a down change )

I have progressed in thinking after looking at budget (ie, I can afford it), and will go with a stroker. I have the first part of the equation, a brand new pair of dellorto 45 drla's. Bewdiful...
Will stay with 90.5mm pistons but go to a stroker crank.
Who has done it?
What has been most successful?
cheers:bounce

Two trians here, if you are going to stroke then stroke go 82 .
Or short stroke and avoid clearancing , with a 76 you will not need any clearancing.
That said clearancing is not a bad thing just some more machining and cost , The real consideration I think is the reassembly with a 76 you can use standard pistons, the width of the motor will be standard or standardish.
With an 82 the motor gets wider you need different pistons , the lateral force (momentum?) will accellerate crank journal wear and etc etc.
The 76 route will be cheaper easier and safer , you will get a longer lasting motor.
BTW what did you pay for a pair of dells? carbs only? where did you get them?
Good luck Mitchll

one question that me be good for this thread. what is the best stroker combo for sub 2L motors? (yes i knwo an option is a 1915) but what is i want a sroker and still stay under 2l for class.

As I said already use up to 76mm stroker, no larger to avoid complications, I saw some cheap 74 stroke cranks advertised , a tad on the short side but cheap.

thats a yankee car !!! c/o the dyno figres ????????

i have this motor i got from d becker, i cant really say to much else about it because i dont know
it has

berg 74mm stroker forged crankshaft
berg stroker vw rods
berg 310 cam 294 duration 0.390" at cam
eaton lightweight lifters
berg oil pump cover and 26mm oil pump
mahle 90.5 piston and barrels
vw 044 heads, ported, 3 angle valve job
pauter dual valve springs, solid rockers and swivel feet adjusters
twin 44idf webbers, k&n washable aircleaners
lightened flywheel full flow oil filter
it has 8.0 to 1 compression

i cant say how it goes because i havent tried it , but does sound like what you want

A guy I know has a 74 x 88 (1800) berg engine. It has been together since 1987. He runs a K8, 40 x 35 valves, IDAs and a 50 shot of NOS. On the NOS it runs low 12s in the 1/4, NA it runs 14s. This thing revs to 8k and breaks gearboxes !!
Jak - look at his 1/4 mile times - 12.718 in the 1/4 @ 103 mph - hes making some serious HP to get there.

Adrian

You should bung that combo on the NZ veedub nuts engine thread- thats sounds an intersting combo.

I'm curious to try either 74 or 76mm crank with pistons in the stock case openings, so probably the 87's.... although I do have a set of 85.5mm cylinders lying around.

Has anyone tried or seen this combination, or have any comments?

Jak where did you see the cheap 74 cranks?

Cheers
Jeremy

Great stuff guys!!!
I have had a busy weekend so have missed the banter, but keep it coming.

Mitchell
The Dell's cost me just over a grand but they are fair dinkum brand new and have an electric fuel pump w- malpassi regulator, full hex bar linkage kit and manifolds etc.

The same guy I bought tham off has a pair of eliminator 2000 heads for sale for around the grand. Not the right timing for me (ie, near xmas)

It does sound something very much like the money.

Jak, why the 74-76mm crank? clearancing issues or motor longevity?

Adrian H
The NOS is a terribly tempting option once it is all together...nothing like a bit of extra horsepower for a short spurt!!

just use the wasser crank 76 stroke

did you think of going FI and forced induction?

that seems to help small motors make big horsepower. and the 1776 seems to be popular for a FI turbo motor in the states.


Just a thought.

Anthony

76 x 90.5 = 1956cc

82 x 88 = 1995

74 x 90.5 = 1904
I think Ben Durie used this combo
