Prospective engine build: 2007

[Mikedrevguy]

Well, okay, first problem
Attempting to remove valve springs, could not budge the keepers from the collars. A little persuasive ball peen freed them, but the mushroomed valve stems won't allow the valves to exit the guides. Plus, the intakes appear to be a bit loose and the exhausts are tight. So, looking at new guides and valves. Yeehaw.

sounds normal to me. Probably not "right" but it happens all the time.
Yes you will have to file the burrs off the keeper groove area to get the valves out. most valves have hard tip inserts now, if the tips are mushroomed you..... had some antique valves? perhaps old manly valves

[Mikedrevguy]

Well, the project I had intended on doing before the drag season will continue: ordered the topline disc conversion kit. Will be in Monday- to be installed. The following Saturday.

Now, if I only had a motor to test them out. Soon and very soon.

This thread has been a fun read!
I've learned a little bit from your ups and downs, and looking forward to seeing how the next iteration goes.
What were your best times with the Kadrons? I'm going to be running Kads on a 1904 for a little while, since I already have them and don't have the extra coin to drop on a set of Webers at the moment.
I'm hoping to get my little ride out on the 1/8th mile tracks near me a little bit, and possibly on 1/4 mile tracks if it does worth a damn.
Are you running full interior and spare tire and all that? Or have you taken a few things out to get weight down? I'll be driving my car on the road quite a bit, but when I am trying to see what kind of times I can get, I'll be removing a few things such as the back seat and trunk goods, and possibly the passenger seat. The cheapest way to adjust power:weight ratio is to drop some poundage.
keep having fun, man!

Thanks Chief - it's been a fun process. I try not to take things too seriously with the ups and downs - it's all a learning curve, and if i learn on the way (and if someone else can learn from my mistakes) cool.
the car and driver weigh 2100lbs - no spare (I live dangerously) and no bumpers. but full interior, rear speaker deck, etc. I may be taking the rear seat out and exchanging it for a platform, more cause it's easier for the dogs to ride along, but may cut a few lbs.
best time with kads - 16.2 @ 80mph - that was with 40/32 heads (non ported)
installed the 44's - 16.2 82mph - with the same heads.
wasn't till I dropped the $$ for the L-5 heads that times went down by almost 2seconds (that and more seat time at the strip?)
what's your motor combo?

most importantly, have fun.

Rev.

Kadrons
Cheapo Empi 1.5 " merged header with a stinger
I'm hoping for close to 100hp, but we'll see....
Entire rotational assembly dynamically balanced.

So, top line disc kit installed.
Everything was included and went together smoothly.
Only downside, couldn't push the car fast enough to really sense a difference between the drums and discs.
Guess I'll have to wait till motor is back together to road test.

I had CB's 2.5 inch drop spindles on discs on my '70 Bug with a mild 1776 and the discs made a serious difference in braking. You'll definitely appreciate it with even more power out back.

I have to admire your stick-to-it-iveness as my frustrations in building a 2017 led to me bailing on high-performance VW stuff altogether. I discovered I'm more appreciative of a stock VW engineering. lol.

[Mikedrevguy]

Heads opened up for the thick walled 92s
Fly cut to 49cc (will double check when valves reinstalled)
Cylinders cut for .04deck - (thanks John)
Shooting for 10.3:1 c/r
I've got Mahler 92 cylinders (2sets- 1used, one new) gonna run wrist pin buttons racking case today to replace bearings and, while I've got the cranks stripped, am installing set of CB straight cuts.
Have new stainless steel valves to lap in and install
Gotta lap the cylinders to the heads.
Then put it all bad together again.

On the chassis side of things- have new rhino trans mounts, rear sway bar (and am ordering a HD front sway bar.
Will be good to go by the 30th ?
Hope springs

Added: grant rings with total seal 2nd.

[Mikedrevguy]

So, while I, here, may as well crack the case and replace the bearings. Right?
Sure, why not.
Well?
Upon initial cracking, revealed the cam and lifters were toast- pitted beyond reason- and lobes worn down.. Oops.
Mark from STRICTLY Foreign researched SLR cams and came up with the XV 304. With same lift, a bit more duration, should be very comparable to what I had, plus, when I move to 1.4s- it'll work there, too?

Crank is going down to get turned- rod journals to be polished



Always something to keep life interesting.

Cam and lifters pitted? that NEVER happens on these
yeah, ok maybe it happens sometimes.

Scat cam, but what kind of lifters were they? I think if they were scat they'd have pits but the cam would be ok

[Mikedrevguy]

The cam/lifters that were pitted were the chilled iron DRD. Talked to Darren; he gave me a run down of possible factors.
-bad break in
-high oil temps-
-too high RPM
There was another, can't recall right off hand.

The new cam is coming with scat lifters that have been SLR'd

Moving on up.
Gonna be a whole new engine, that's for sure

[74 Thing]

What exhaust are you running?

What ignition too and what timing? I was reading the thread and an earlier post you referred to a miss (wonder what the problem was) and a lot of total advance.

[Mikedrevguy]

I've played with both 1 1/2" and 1 5/8" merged -

the errant jumping I was reading at the Tach went away when I changed the hot spark back to points in the 050 distributor.
I've got a 009 in now - that's been reliable/solid.

Pulled bearings, crank being turned - will be done mid week.
Cam is on order- will be in mid week.

Installed rear sway bar.
Purchased the necessary installation pieces parts.

Am installing in another case - one that's been prepped by Paradise Motors.
Will have a deep sump (need to get all the requisite studs for this motor. )

Excited to get this back on the road . . . Again. . . .

[Mikedrevguy]

yeah, Al, I hear you on the question/concern. was surprised to see the SLRs advertised for 1.1 1.25 1.4 rocker assemblies. Iv'e got that question out there waiting to be addressed.
my heads DRD says are good to .600 lift, and with the 1.4 i believe it puts it at .588 - but, we'll jump off that bridge as we get there.

So, just stumbled into an MSD 6AL kit with the distributor and Blaster2 coil and all requisite wires.
so, that'll add a new curve (all pun intended) to how the motor, engine bay, etc is assembled.

thanks for the feedback.

[Mikedrevguy]

any hints, heads-up, warning about installing MSD?
anything i should be aware of? Blaster2 coil, can it be installed horizontal?

this will be a new venture in this motor
