So here it is...

125" chrome molly Mark Williams chassis 23T
9" sheetmetal diff housing
Strange bolt through carrier
35 spline Strange spool
35 spline Romac axles
Strange carbon brakes and calipers (4 wheel)
Willwood master cylinder
DJ Safety 5pt harness
Stroud parachute
Custom alloy radiator, thermo fan
B&M Pro Bandit shifter with electric solenoid
Spritzer carbon wing and scoop
Sheehan Nose Cone
Fiberglass body

I will be using the motor which I had built for the previous project, but will be making some changes as the motor will be run naturally aspirated for awhile (more details to come later..)

Transmission is a Powerglide built by Protrans, SFI rated casing etc, with a transbrake. Converter is the 4200 built by TCE that I was using in the previous project as well.

I will race this in A/MA trim (Modified) bracket. This is group 3, dial your own racing, so consistency is key. I will be retaining the stock GM ECU - obviously retuned, however this combination should prove to be extremely consistent, reliable and mostly maintenance free.







And lastly, have been busy over the last few nights getting an old LS1 block and the powerglide into the chassis for mock up purposes, so I can get the front engine mounts made up to suit.

New motor specs, afew things have been changed due to running naturally aspirated:

5.7ltr LS1
Mahle pistons
Eagle rods
Stock crank
238 242 @ 108lsa custom grind cam
Lunati Dual Valve Springs
Morel "Street" Tie Bar Lifters
ARP Head Studs
ARP Main Studs
SLP High Volume Oil Pump
Double Row timing chain
Edelbrock Super Victor Manifold
Edelbrock "Competition" 4-Barrel Throttle Body

Heads will be a set of "241" castings which have been CNC'd - I am waiting until we get the cam in the motor to check PTV clearance, and then heads will be decked accordingly.

Compression with 0.40" decked will be 11.05 : 1

With 0.60" decked will be 12:1

I really hope I can deck 0.60" to get higher compression, and in turn run "E85" (race fuel - really E95) and get better results. Time will tell I guess.

I have done some small things not really picture worthy, mounted the delay box, finished removing unnecessary things from the LS1 loom.

Alot of the parts I had to order have turned up, so I figured this was at least worth a photo, just mocked up:



Cam has turned up, so this weekend I will be pulling the heads / cam / lifters / pushrod from the engine, installing the new cam and then checking piston to valve (PTV) clearance. From here I will be able to make a decision on how much the heads can be decked. Then once the heads are back, I can measure how long the pushrods need to be.

Also been working on the front motor mounts, just have them sketched on a piece of paper for now, which I will take into the local aluminum fabrication shop who will cut them out via laser for me. Also going to be putting a nice rebate in the back of the plate so it will fit the stock LS1 water pump gaskets in nice and flush. To give you guys an idea of what the plates look like, here is a similar picture borrowed from another forum:

Front engine plates being made up:



Not much else going on, awaiting more parts to turn up - specifically the heads at the moment, so I can check for PTV clearance and then send them off to be milled.

Just done some little small things lately..

1. Design new parachute handle that is abit longer, old one had literally 1cm clearance above my leg. Not my idea of fun at the end of the track, so a longer one was in need! Just a template obviously, new one being CNC'd out of aluminum.



2. Swapped switches on the dash from the left to right side - all the important ones are now on the right side, which allows me if necessary to cut the fuel & ignition, and hit the parachute with one hand as everything is now on the right hand side. Previously I would have needed to hit the chute, then grab the wheel, then hit the switches with my other hand. Just a little thing that could be handy.



3. Mounted, and wired up the delay box and started to make some headway into identifying what wiring I need, what I need to relocate etc. For those who do not know a delay box is, I stole this:

Some people don't like them as they consider them "cheating" - but at the end of the day, you still have to react to a light, you can red light or have a horrid reaction just like releasing on the bottom bulb.

That wiring box mounts on top of the gearbox. Room to mount things is kind of limited in this sort of "car"



4. Lastly just some more engine ****. My CNC'd heads turned up today, so some real action should start happening soon!

Have been working on plumbing up the race car this weekend. Did as much as we can until a decision is made on the sump. All SpeedFlow gear of course.

Got the CNC'd front engine plates back, and installed them tonight. Forgot to take a pre-install photo showing the rebate CNC'd at the block side of them for the gasket for water. Will try and remember to get one when I pull it apart for final assembly (still got the mock up engine in it)

Latest update is I am *STILL* checking engine clearances.

PTV came up really big, like 0.350" of clearance +

This is probably just due to the pistons having 4cc of valve relief in them, but I just want to be really sure before I go and get the heads milled.

This has meant going back to step 1, checking if the cam is degreed correctly, checking pushrod length and then checking PTV clearance again.

Just waiting for a pushrod length checker at the moment.
