ESPSIX

Its funny, when I see people here and on FB asking for parts like these, my first thought is, “ha, didn’t realise they were that hard to come by, I’ve got half a dozen sitting in the shed”, but things like lip spoilers, I got when you could get them for $10, now, I just feel glad I’m not trying to build a car now days.

You call it hoarding, I call it, having spares of parts that you can’t get anymore.

Yes you will, but as chestnut said, will be the larger, so better for less cavitation.

I’ve done it, on the car, no issues in years, but went slow. but why don’t you just buy the non viscous fan water pump?

From memory ( I did it 10 years ago ) the original boot works, but I got rid of the rubber block thing on the gear stick, then bolted the top half of the stick to the wrong side of the bottom half so the top half lined up better in the console hole. sorry, don’t know how else to explain it. and don’t have pics.

That is the HKS set up.

They’re both AIT set ups.

I use Castrol TransMax Z.

I think you’ll find they are supposed to be blocked off, when you open up the holes the water will just find the path of least resistance. the water is supposed to flow to the back of the block before it enters the head, where it then flows forward to the outlet ( thermostat) and in to the radiator for cooling . by doing what you doing, the water will just flow through the block to the first opening to the head, before flowing back to the radiator for cooling, leaving the rear of the motor to run hot, causing the head casket to fail.

As Bear351c said, are your fans spinning the correct way, are they coming on at the right temp, are they fully shrouded?

A tired old 302 to a nice tight 351 with a bit of core shift might just be enough. it doesn’t sound like it’s over heating, just running hotter. some people love the Aussie desert coolers, the few times I’ve had personal experience with them, I’m not a fan. easy to swap out a radiator to find out if it is the issue.

See my first comment.

I only mentioned the head gasket because it is an easy mistake to make, it blocks the water gallery where the water passes from the head to the block at the front from memory, but it makes the motor run quite hot, so that would be the last thing I’d check and if it’s only one, only the head affected would be hotter.

Yep.

Apart from the crappy radiator, is the thermostat actually working, do you have the resrictor plate under the thermostat, what kind of water pump are you using, the ones with individual blades can have cavitation issues, are the fans fully shrouded, and are your head gaskets on the right way, although it doesn’t sound bad enough for that, the heads would be getting very hot.

Get rid of the desert cooler for a start.

Message bullfrog, he reproduces the black wheel nuts.

The T5 loves the transmax z, the shifts are much nicer! im doing a full seal and gasket change on the single rail on the weekend cause it leaks from everywhere.

What oil is everyone running in their Single Rails, I run Castro’s Transmax Z in the missus’s T5, can I run that in my Single Rail?

Correct, But whether any of those boxes are behind a 6, or a 8 makes no difference to the gear in the box, or the gear on the transducer. eg: a single rail out of a V8 will bolt in, and plug up in a 6 cyl car and read correctly as long as the transducer gear is right for the diff ratio. as did the 6 cyl T5 I put behind my missus’s 351, but had to use the XE transducer, which was a 6 cyl one. OP didn’t say which box he is running now, but if it has a later than XE transducer that would make the speedo play up as XE and later have a different plus rate.

I don’t think so.

Possibly missing the restrictor that goes under the thermostat. Or, head gaskets on backwards, very easy to do when fitting the heads.

There’ll be a roll pin in a hole that goes through both half’s of the selector shaft, knock it out with a pin punch. go buy a casket kit for a single rail and change all the gaskets while your at it.

Check the bleed nipple is not blocked, pull it all the way out, and try pushing the peddle slowly, and see if any fluid comes out. ive even had the Caliper blocked with crud.

I may have an adaptor from the plastic body to the teardrop body I'll have a look if your interested.
