Stumps

Been digging through my shed and I found a Thermoquad of a XC 302, im pretty sure it was a manual it has the part number TQ 9091S on it. Has anyone ever tried one of these on a 4.1litre? I'd imagine the stock 302 jetting wouldnt be far off what would be needed for a worked 250. I remember Blue 253's having a quadrajet on them and they went pretty good with those. Would a 250 respond the same? I've seen plenty of holley 600's on 4.1's and they work pretty good, surely a TQ with its smaller primaries would be more economical at cruise and the secondaries would on flow as much as what the engine could use given the air flap restricting airflow to them. Anybody given this a crack?

I measured up the input shaft its the 6 cylinder one 167mm, the V8 one would of been 20mm longer if I remember correctly. Doesnt really matter at the end of the day...a T5 is a T5, it'll break once I put some power through it....wish I could be as certain on winning lotto.

According to goggles that number correspondes with a Non World Class mustang T5....confusing Pretty sure its to box that'll only take 300lb's of torque...better be gentle with it

Pretty sure the first gear is 3.25, the ute was effortless in smoking the rears in 1st or 2nd and first ran out wayyyy to quick. I could be wrong but I think the XG longreach had a 3.25 as the first gear...I'd have to find the service manual to check.

Hi Guys, I recently picked up a very clean low kay (76000km's) XB falcon 500 sedan and I'm looking at putting some decent wheels on her to give her the look she deserves, it currently has the stock 14in wheels with 205 rubber and looks pretty ordinary, for some strange reason the arse end has been lowered 1 inch with lowering blocks which I intend to get rid of...I hate those damn things. I'm not intending to lower the arse end as they sit pretty low from stock, but I'll knock an inch out of the front to bring things more in line. I need to find out if the wheels and tyres I'm looking at will fit under the arse end without having to roll the guards. I wanna fit B45's or V5's in 15x8 on the front with 245 tyres and 15x10 with 265 or 275 rubber on the bum. Will these fit the sedan? I have seen plenty of XB's with 10's on the bum in the past but never really bothered to look at the actual fitment.

I'd have to climb back under the car to take a pic, but i've measured the input shaft and its only 167mm so pretty sure the box is a six cylinder one, maybe the extension housing is from a v8, thats what i took the number from. Its marked 0552-0662903. Once I clean the rest of the box I'll see what numbers are on the the main housing. I do know the box has a lot less kays than the rest of the car. It'll do until my funds start to recover and I can get a TKX in to it

it's a 3.27 and yes it's out of an XG. I'm trying to figure out what the T5 was from as the ute originally had a 4spd auto in it and was converted to a T5 about 10 years ago by Dellow's. The number that I have found indicated that the box is from an EB2 V8, but thats just from a google search, gunna have to drown the poor thing in degreaser to find the rest of the id numbers on it.

this one pulls pretty good down low, it runs out of breath after 130km/h but still is pulling ok, havent had it flat out but I reckon it might hit 150ish if the road was long enough. Around town the 3 on a tree lets it down, first is useless above 20 and you spend most of your time swapping 2nd and third, I can't wait to get the 5 speed in it, still collecting parts to do the job properly.

Thanks, been looking for a colour code 5 deep aqua XB for 28 years...after I crashed the v8 futura that I had as a stoopid stoopid teenager. Wife finally let me get one, she's only a 250, but as we all know they can be made to go real hard. the Vinyl roof has slight damage on the driver side near the chrome trim, so I'm weighing up wether to remove it and get the turret cleaned up or fork over and redo the vinyl.

Pulled these out of the ute over the weekend got a nice surprize found the diff is an LSD which is handy....also discovered that I'm way too fat and old to be climbing under cars in the cold..

Just thought I'd give an update on this one, went for 15x8 and 15x9 12 slotters with 225/60 and 265/60 rubber, came out looking better than I expected.

still looking in to carbs for my 250 2V engine, do I want vac secondaries? or can I go with mechanical secondaries on a 4 barrel carb, will it make any real difference using one over the other? I remember old street machine articles about carbs and they used to state, go vac secondaries with auto's in heavy cars and mechanical with manuals in lighter cars. My XB isnt a light weight but it's certainly nowhere near as heavy as a late model falcon, and I have a manual gearbox?

Yup it sure is, im in the hole right now for $3200 for the suspension I just put in my XB...still got lots more to do..lol

Was the quickfuel a DP or vac secondary carb?

What cam were you running?

What about Edelbrocks, the AVS2 seem to be updated versions of the old AFB carters that Val Pacers ran....did they ever fix the hard left hand cornering fuel starvation issues those old carters had, surely 50 years on that would be well an truely sorted with the design.

Thanks for that, mechanical secondaries make 100% sense on a turbo for sure. Just dont know about the non turbo route. Most of the carbs Im looking at are vac secondary carbs like the TQ or Quickfuel 450cfm carbs. The 4360 economaster carb is a mechanical secondaries so its the odd one out. Feel like banging my head on a brick wall, way to many choices...

Does anybody know where I can get a knob? ok, get ya minds out of the gutters...... Does anybody know where I could get a custom gear knob that looks like a 70's falcon 4 speed knob but has the pattern on it to suit a 5 speed gear box?

Has anybody tried out a Holley 4360 economaster on 4.1's? Being only 450 cfm I'd assume that they would be almost right on the money for a mild cammed 4.1.

Hmmmm N2O...now that could be fun...shame its illegal for street use.

Yup 100% agree and its a shame I always wanted a supercharged 4.1 even as a pimplely teenager on my P's back in the 90's cruising around in my XC. I have messaged CAPA about this kit to see what sort of pricing, I'd expect around 7 or 8k from them.

But if the blower could be wound up to 10 psi, it'd probably come close to the power i'd like to have. Shame CAPA kits are notoriously expensive for the power they produce. Would be very cool however.

I'm a bit wary of the ebay kits given all the cheap chinese knock offs floating around. The DSM kits look alright but never really heard of them before. Are they cheap chinese crap or considered pretty good? I was looking at possibly converting either the factory dizzy using a pertronix kit or getting one of the xe or xf dizzies that I have modified to suit.
