Boring 128 linkage stuff

 

 

 

 

I found some tubing that had the perfect inside diameter for extending the original rod, I modified the bracket on the end to bolt to a stud on the exhaust manifold.

Big valve head installed

Ready to drop the head on

These are what the DCNF's need!

Say goodbye baby

 

Michael Lemus will be the new caretaker of the 600, I supplied him with a short block that has high compression pistons, that should make baby go even better then ever.

Mo Powa for Mayuko's 128

I'm installing a big valve fuel injected head that has the piston outlines shaved off to bump compression, it has 40mm intake valves with stock exhaust valves. A Faza 35-75 cam will provide the lift and a set of DCNF's will supply the air and fuel. We will keep the stock 74 exhaust mainifold and custom exhaust. I am waiting for the new water pump from Midwest Bayless to arrive to bolt it all together.

Say goodbye to baby

X19 bumper mod

I'm sure this has been done many times, but here is my take on modifying the ugly 76 style bumpers with out spending any money. The whole job took abo+ut 2 hours. I disassembled both bumpers and used the upper bars. I turned the brackets that are part of the piston assbly. 90 degrees and bolted the top bars back on, the front brackets were bent a little to match the bar angle. I cut the rubber ends with a sawzall and sanded them with my 10" sander. Approx. 60-70% weight savings and much better looking. Before and after shots.

Fiats at the 2010 Oregon meet

This only about 1/2 the cars that were at the meet, blame me for getting the organizer back late to get everybody in one shot. The place is Howard Prairie resort in southern Oregon, they run a nice place and couldn't be nicer people.

GMC and 600

Piggyback 600

We hauled the 600 and boat up with my GMC 3/4t, the Starcraft is light at about 1200# and the 600 wieghs in at about 1200. I built a small ramp inside the bed and used 8' ramp boards. It was a little exciting getting it up there the first time.

RIP 903 engine

I blew up the 903 over the weekend racing in Oregon, there is some kind of metal on metal sound coming for the engine with a big loss of power. Anybody want to buy a cheap 600? Or does anybody have a used 843 or 903 short block for sale?

128 got cleaned up for vacation

We freshened up Mayu's 128 and painted the wheels for the upcoming Oregon meet. Mayu will lead the way and I will follow with the new toy hauler, it should be an interesting trip. Towing the Starcraft with the 600 in the bed if the truck.

New to the family

Couldn't help ourselves

low mileage X that needs a head gasket

Comes with the gasket set

36 DCD tuned and ready

The Weber 36 DCD has been tuned and installed, main jets 135 air jets 200 idle jet 50 with 25mm chokes
The head was match ported to the manifold, the choke was removed and a custom throttle lever was fabricated. Make no mistake this engine is fully capable of suking al the air and gas this carb supplys!

Rough specs here:
903 engine
PBS ralley cam
balanced and lightened flywheel and pressure plate
Weber 36/36 DCD carb
S/T cam gears
9.5? compression ratio
Fiat 127 water pump
Fiat X19 electric cooling fan
Flipped top spring in front to lower car
Cut rear springs new shocks
850 front disk brake conversion
Fiat 124 spider steel rims with RE potenza 165-65=13 tires
I will pull the engine soon to change to front main bearing seal to the reverse rotation style
Also hope to auto cross/solo this summer in the under one litre group

Spider rear end

A couple of notes when changing to a early diff in a late spider, chase the lug bolt holes with a 12mmX1.25 tap, I used a L bracket that was custom bent to hold up the bracket where the hard brake line meets the soft line it bolts on to an existing 10mm nut on the diff case close to where the caliper bracket is attached, we decided not to use a backing plate giving better brake cooling? All the upper and lower diff locating rods are the same and bolt right up.

Rear ends

Mayuko's spider diff was making a lot of noise, terminal noise. We decided to go with an early pre 1978 style as a replacement.

Here are the parts you will need for the conversion:

*early complete differential with axles (don't forget the shock attachment ears)

* early style straight pan hard bar

*pre 78 back half of drive shaft (or not)

The most common gear ratio was 4.30 we found a 4.10 which is a little closer to the original 3.90 her spicer style diff came with.

You just unbolt everything and carefully slide out the old unit, her springs were cut so no need to compress them, and the brake lines will move out of the way after cutting the wire tape that attaches them to the housing. You don't have to undo any brake lines.

Fill the diff with oil while it's out we used 80-90 EP oil, about 3-4 pints or until it runs out the fill up hole.

We opted to use the original drive shaft which is about 10mm too short, just loosen the drive shaft center support bracket and slot the holes a little then tighten the rear drive shaft to the diff then tighten the center support bracket. It's about a three hour job if you have two monkeys working together.

Photos shall follow.

More DCD photos

Those with sharp eyes will see that I made a cover in place of the choke assembly and I had to make a new cover for the throttle assembly so the lever would clear.

Valve cover side relief

Its a little bigger then the 30 DIC!

Head modifcation for 36 DCD

This is the area that needs to be ported out for the S/T manifold and 36 DCD carb, the head is pretty thin in this area so cutting it with a die grinder and cutting bit should be pretty easy, I will leave the head on and stuff it with shop towels to catch the grinded bits then vaccum it out and reinstall the head bolts.

36 DCD carb and S/T manifold

I will mount this manifold and carb to the 600 shortly, the intake hole will have to be ported to match the Scuderia Topolino manifold. Paul a S/T recommended jetting and 25mm chokes which I sourced from Pierce Manifold in California. The go to place for all things Weber.

John's 3P

Here is Scratchy Bottom reader John's sharp lookin' 3P. I have yet to see either an SL or 3P on Bay Area roads since I've owned mine although I did hear of a
3P going to the crusher not too long ago :(
