Al - talked with folk at Pierside Parts - with the 1.4 rockers and the XV304 cam (SLR) would be for heads that are 46/40+ - and, as t's pushing .600 lift, recommend having the lifter bores sleeved.

1.4 would not be just a bolt on addition for power for this particular cam in my current configuration.

and so, with the ever evolving nature of these projects - - here goes:

out with the cast crank with porsche rods (that will re-emerge in the winter driver motor (2007) Actually, thef 2007 will be resurrected with the same original heads, same crank and rods, same p/c's - - so, really what I am now giving birth to is a whole new engine?? In the winter, I'll run heater boxes and just not jump on it quite so hard.

here's the rundown on the 2074 -
AS41 case: decked, clearanced, welded 3rd etc by Paradise Motors.
TW 92s with Mahle pistons
78mm forged bugpack crank
berg 12.5# flywheel
stage 2 pp - with daiken disc.
(all of these have been spun/dynamic balanced)
Scat 5.4 rods
SLR SV304 with scat lifters that have been "SLR'd"
L-5 DRD opened for 94 : flycut to 49cc
.04 deck for 10.3:1 cr
full flowed

let's see what we can do to get this motor together for the May 14 Oregon Dub-in - at Champion Raceway.

received rods and bearing,.
Crank is going in to Lindvig's for its first cut on both main and rod journals.
Got engine bay cleaned up. -but still haven't decided what to do with the diagnostic plug- remount or clip the wires, seal it off and call it good until the body off restore at some time in future.
Now to:
Weigh and balance the Pistons and rods.
Check lifter /case clearance
Mock up-
Set deck height and end play
Check rocker geometry

Disassemble
Clean everything good one last time and reassemble.
Easypeasy - voila- 2074

Short block is ready to be buttoned up.
Deck is .045- with the 49cc chambers gives a 10.2:1 c/r.
Hopefully, this weekend I'll fire it up and break in the cam.
Then install it and put a few miles on it before Woodburn on June 4.
Gonna be tight.

Don't remember who balanced the crank/PP/ and flywheel. Should probably ask again and remember it.
Pistons I used came within gram of each other (3 were on, one was out)
Rods came from SCAT -one was under, but when I installed bearings, all evened out.)

Rimco did the balancing back in 1999-2000.

Shortblock is together.
All rotates well, smoothly. No binding, no pinched bearing/dowel pin. Off to a good start.
Let the long lock assembly begin.

Of note: the oil pump, when I pulled it I payed no attention. In preparing g to install that, I did notice some binding of those gears. On closer inspection, the individual veins in the gears looked like a micro serrated knife.
Compared it with one I had on shelf, and there was notable difference.
Discard the serrated geared pump and put on list to purchase another for the next build.

Got motor together and in and fired last night.
Was not without 'issues' -
Installed distributor 180 out while assembling the shortblock. Did not realize til I was adjusting the valves. Oops. After futzing with it- could not get the drive to come free enough to re-orient - it's 180 out for a while.

On mocking everything up, I had zeroed in on a .004 endplay- when I assembled (without main seal) I had .008. I thought I could do better.
Collected the right shims and installed. Torqued it down - nada. No endplay. Zero. Smh
Before readjusting the shim pack- pulled main seal and tested- sure enough, main seal was the binding factor.
N nob b. B n. V vvvbnbnn (sorry bout that. Fenris wanted to contribute- Fen is a 4mo. Siberian Husky)

Main seal. Installed fresh main seal- counter sunk it (not flush with case-) and have .0035 endplay.

Trifecta- building oil pressure (oh of minor report- cross wired the 3/4 plug leads- even after labeling them - Fen probably has more sense than I at this point.)

Building oil pressure- it wouldn't.
I had filled filter and primed the lines and the case (gravity fed) Cranked cumulatively less that 2 min. Nothing. Fired a couple of <2sec bursts. Nothing. Pulled oil pressure sensor- oil there.
Pulled oil line to filter- (verified I had not swapped the in for the out) no oil.
Asked my partner in life and in crime to turn key while I watched the unattached line- nada.
Why is pump not pumping.? Primed the pump and repeated previous test of watching disconnected oil line- we've got oil.
Reconnected and voila- we've got oil pressure.
Connected. Uffler, and spend 20 minutes sitting in driver's seat drinking a Guinness while holding the car between 2500 and 2700 rpm. Now, I get to pull it and pull heads, insert the center springs in the heads, look at/for and oil leaks and address. Reinstall. Drive it like a batouttahell and be ready for Woodburn on saturday. No problem.

Glad to see that case was only cursed for me...lol At least someone is getting use out of it. Laughing

I'll be looking for you at Woodburn this weekend... think I can switch shifts with someone so I'm going to try and swing it.

2074 is. And running.
1st pass at Woodburn - 14.52 @ 96
Last pass- 14.09 95.5

Once we get the launch down, I believe we may be headed to the 13's

And with a valve adjustment, oil/filter change, removal of stinger in favor of the dual quietpack, and swapping out the power pulley for the standard, we go from speedy drag car to mild mannered daily driver.

Replacing locking spindle bolt in front passenger assembly, and then I'm ready to put more miles on.

Oil had a bit of pearl essence, but I guess that's to be expected with only 30 miles on it?

Question- what led there be any difference between power pully and a standard pulley were I to (at the track) loosen them up to allow for slippage ??
Thanks in advance.

Pearl essence? Like shimmery metallic? I would watch the valve adjustment carefully.. Hopefully your cam is not going bye-bye Confused
