Pic 1. The 2 inch timber is to hold it in position, which shows the portion underneath that has to be trimmed.

Pic 2. Friggin big lump of a thing..... i'm still having trouble getting my head around the HP these things make.

Pic 3. Once we remove the timber from behind, the engine will slide back enough to clear the radiator support panel. Keep in mind, the radiator sits in front of this panel. Could've cut it out for an easier fit, but that's just being rough and lazy.

Pic 4. Had the Caddy out yesterday and bumped into Cadillac Jack in my travels.

Can't drop the front end out and bring it in from underneath?

Nah, not really.

The engine needs to be able to come and go through the top.... and it will.  ;D

After you've reshaped the firewall, it will just be a matter of what angle it gets rotated to, and how much height you have/need.

Gunna be fun..... ;D

Your changing the firewall, tunnel, steering, springs and brakes but ya keeping the top of the radiator support 'original' even when it makes life difficult sooo.... you can lean on it self righteously when you pop the bonnet?
I get that you know and trust the th400 but could you have added a few more gears it's 2020.
The wifes merc has an 8 speed and the box handles up to 6-700 hp before  upgraded clutches and solenoid work and it seems smaller than I remember  my old tonner box same with the diffs.

The radiator support panel is a load bearing portion (not by massive amounts however) and as we are cutting the firewall, it stays in as a brace to help keep the car square.
It doesn't really cause an issue, even with it missing, the firewall still has to be trimmed anyway, so there is no advantage to cutting it.
If you look at Pic 1, I have a block of timber behind the engine.
If the firewall was cut away yesterday, the engine would have gone straight down and into position.
These things are always, a steady as you go situation.
I only want to cut away, what is needed, not just cut out bits to make something ever so slightly easier.

Geez, I need an 8 speed auto like Custer needed more Indians.
The 4 speed Ford box was a consideration and the 6 speed Ford box is stronger, depending on who you talk to.... however.

I need gearing to suit n 1/8 mile strip as well as a 1/4 strip and still be able to cruise the highway.
To use an 8 speed box, i'm making 7 gear changes in 9.5 seconds with the diff gearing done to suit. That's getting pretty busy.

We are also using a transbrake set up, which can be done  easy on a T400 trans.
A 2 speed powerglide would work well too, but the gearing isn't there for 1/8 mile tracks.
Not too sure, a Merc 8 speed would handle that sort of abuse.
We will hold around 3,500rpm while the transbrake will lock up 1st and reverse together.
At this point, I have my foot off the brakes, the gearbox is holding an engine that is now making boost.
On the drop of a button, all hell is unleashed on the driveline.

If I was just tootling around town or down the highway..... for sure... an overdrive everyday.
I have the option if I want to, to fit a Gear Venders overdrive, as they can hold up 3,000HP, but aren't cheap.   :'(

Keep in mind, this car is being built to compete in a Drag Challenge event.
You race Day 1, hand in a time slip and get you route map to the next track, often around 350klm.
You race Day 2, hand in a time slip and get you route map to the next track, often around 350klm.
You race Day 3, hand in a time slip and get you route map to the next track, often around 350klm.
You race Day 4, hand in a time slip and get you route map to the next track, often around 350klm.
You race Day 5, which is back at the 1st day race track again.

Depending on where its held, you also have the klm to get there and get home.
The gearbox cops a hiding in these cars, I really want to attack this with a boxing glove, not a mitten.

I can’t imagine a chassis that has had a fire ‘near’ it being structurally robust enough for just returning to stock, let alone the sort of power these guys are talking about  ??? ???

Willowbank, Warwick, Roma, Bernaraby and back to Wally bank.

There is also mackay and Spring Mount, even Stanthorpe has a little 1/8 mile.

And yes, the car will piss it in. With Footy Shorts Shane and myself twirling the spanners, if we won, we'd do a victory lap.  ;D

Not defending Ford, but the Barra which is what is being used was/is tough as nails, Penty of reports of them doing over 1,000,000km in Taxi's back in the day, wouldn't expect anything like that with the boost jeepers is going to shove up its clapper, but still plenty of high power boosted barras being quite reliable. With the Haltech, he can easily switch tunes to make it very road drivable as well.

The plan is for only 20 or 22lbs of boost when racing.... 26 tops. (race motor)

The plan is for only 8 or 10 lbs on the street.  :angel: (street motor)

The ones making the huge HP figures, are getting up to 50psi up  their blurters, even these ones still street drive ok.
Hmmm... Haltech.... that's the go.

Back on the Z car today, spent yesterday working on the pool. (still digging Shit out of it)

OH PISSER......

With the Skyline front end, we gain a bit in the front track.
To keep the engineers happy, and stay in spec, I ordered some 3 inch back spaced wheels.

The guy had 2.75 or 3's, 3's were good.

Then he rang me, I have a pair of 3.25 inch back space.

Hmm, yep, should just sneak it in and work a tad more in my favour...... pisser, just fouls by the tiniest amount on the friggin caliper.

So, box 'em up, send 'em back and get the 3' inch backspace ones I ordered in the first place.

Plenty of room for the plug change. There is more room than the photo shows.

Compression gauge is a screw in unit on a flexible line.

The foot wells aren't too bad. Again, the pics don't show it as good as it could.
More foot room then my V8 Datsun 1200 had and it was pretty comfy to drive.

Because we are using head studs and not head bolts, the head won't come off in the car.
Funny enough, 30 years ago, the V8 1200 used studs as well and they didn't come off in the car either.

Not sure who it was, but someone mentioned fitting the engine from below.
When I do the final fit up after paint, it may just get fitted from beneath to ensure we don't chip the fresh paint..... time will tell.

Is there science behind the #1 pot sitting inline with the strut towers?

I would have thought with that much hp a little more weight in front of the wheels could be a good thing?
