 |
|
The cam card info says it was measured with zero lash, Going to go back and do that and see how the numbers look This bug pack Adjustable cam gear came with Gold Washers for (+-4'), Silver Washers for (+-2'), and Black Washers for (0').
Any reason why advance would help MPG's?

What about Retarding the cam? To some extent it changes the valve timing to make the Opening Numbers a lot closer to a more stock-ish cam grind like the Webcam Type 1 Grind #86: If I retard this Webcam Grind #118 just 4' then the numbers I'm reading look like this actually pretty close to the 118 grind specs, still nowhere as tame as the 86 though!
Zero Lash:@ .050" Numbers:
Intake Open: 14' BTDC Exhaust Open: 49' BBDC
Intake Close: 52' ABDC Exhaust Close: 13' ATDC
Intake Lift with 1.1 .409", duration 246'
Exhaust Lift with 1.1 .405, duration 242'
Any advice, thoughts, opinions?

what is the lobe center of each grind? Also there is nothing wrong with calling Steve at Webcam and asking him an opinion.

The Intake full lift points or lobe center is 116' of crank rotation ATDC and the Exhaust lobe center is 120' BTDC, To get the correct 108' Cam Degrees LSA I had to use the Open/Close @.050 numbers then it comes out 108.25, I could try going on each side of the center say .1" of lift and calculate the actual lobe center that way because there is about 8' of crank rotation where lift is unchanged at full lift.

|

I have been trying to get back to building this spare engine. Finally got the Grant Rings for the 88's, and have been doing the balancing of the Pistons, Rods, Wrist-Pins etc... could not for the life of me get reliable end-balance weights on the rods though. Just settled for matching their total weights, they were already very close. Here are the Photos:

|
|
Ordered the Heads, going with L3's sent my ports to have them matched. Will be going with these: DRD L3 Heads. Ask to have them CC'sed to 53cc of chamber volume.
I need to decide where to run the retard on the Webcam 118, I found it's Open degrees to be similar to the Webcam 163 cam card. seems to be almost the same cam but with less lift! If I run the 1.25 Ratio Rockers it will have about .460" of lift. on both Intake and Exhaust.
I kind of hate to advance it because it's already out there and if I retard it that may take away torque so probably will just run it Zero Advance.
Have pretty much everything but want to get an engine stand before I start the final assembly.

|

The L3 Heads Arrived, Now just need to decide on cylinder shims.
Given:
Bore 88mm
Stroke 74mm
Deck measured 16"-18" Thousandths no shims,
53cc heads,
Calculations: CB-Performance Engine Calculator
With .020" shims and .018" it would be 38 thousandths total deck height.
Compression Ratio would be 8.6:1.
Without shims .018" Deck would give a CR of 9.1:1.

Were the head studs extremely clean and then oiled?

Did not oil them but they did have some paint on them! It did not feel like the head nut stuck or anything. Just a couple of sharp rings from each head when torqued!

I'm late to this party, but how did the barrels fit in the heads?, slight side play or tight?. Any lapping compound left on the sealing faces?. Any head gasket rings used?
Might try a loosen and retorque, but crunchy noises either mean something forcing itself past something or cracks forming, I assume you put a straightedge across the barrel tops to confirm they were all even?

The barrels were about right as far as hole diameter. Loose slip fit! You know I never did any surfacing on the cylinders as everything is new. The heads were pretty clean looking but may have been somthing still on them, I did not think to clean them! I don't know It may just be my case inserts! I think they may be moving! No gasket! Just .020 Shim.

So what should be used for the threads on the studs that go into the heads? Anti seize? Threadlocker?

If you mean exhaust and rocker studs nothing at all is fine, but a tiny drop of blue locktite on the rocker studs wouldn't hurt. Neverseez is handy on the exhaust studs later on down the road.

Thank "Bus Daddy" That was jsut the info I was looking for. I wound up putting blue threadlocker on the intake head studs and the Rocker studs! Anti Seize on the Exhaust Studs.
Still need to find:
a short fuel pump push rod or electric fuel pump and block-off,
fan hardware: shims, fan nut & washer,
alternator pulley, nut, shims,
Exhaust port gaskets that fit, stock may be ok not sure?
Carb and mainifold gaskets, Jets and venturi?
Carb linkage, stacks and air cleaners.

|

Next Which Spark Plugs to Use? I ordered the Bosch Super W7DC0 (which is what my 924S uses) thinking they would be a good choice for the L3 heads which have a 14mm 3/4 reach plug hole. But side by side with the 1/2" reach I have been running on my bus, I can tell they may be too hot! What about the W7DC0? Can I get away with running them in this (74mm stroke X 88mm Bore 1800cc type 1, 8.7:1 CR, Webcam 118, Dual 36mm Dellortos) engine?

I just realized I forgot these little deflector plates on the L3 Heads! Are they even needed? Will they even fit these Chineese 043 Style heads?

The deflectors on mine are a loose fit.. your heads look like the deflectors will fit. Don't loose any sleep over how snug they are.
