I must be missing something.
Why would a (relatively thin) stainless flange cause these problems when the cast iron block does not, if the block has a lower rate of expansion and has a larger temp difference to the Al. head?
Also why would a manufacturer use a mild steel flange on a...
Hello again
Once more I need some technical help from the experts this time on a header system that I am looking at building.
I have a fairly old straight six engine with an aluminum cylinder head that comes with two cast iron manifolds. I want to replace this with a stainless header system...
Thanks for replies. I have accepted the large ratio was just making sure my only problem might be a harsh ride, I didn't want any nasty surprises.
It's not a truck just a car on a truck like chassis, not my design and components had to be chosen on what was available not what limitless money...
I am referring to the complete car not just the IFS
Wheels and Tyres are 80lbs combined - 320lbs
IFS is 50lbs (hubs and brakes) a side.
Rear live axle is 200lbs without leaf springs.
So at least 620 for unsprung.
Chassis is 300, body is about 600 (composite) including fuel tank, seats...
Thank you for the reply Greg.
Your point about 'driven condition, not kerb weight' is duly noted, and I assume you mean with driver, passenger, cargo, fuel etc. I can only assume the rest of the suspension geometry is good as my knowledge is pretty limited.
Which leads me to another question...
Hope you experts can help me once more with the project I am working on.
I am installing an independant front suspension based on the Mustang II. This is an aftermarket unit built for hotrods etc something like this one.

Sorry - mistake on the tyre size.
That should be 255/70R18.
So if it comes down to parking does that mean in regards to steering the car if I go with power steering I will lose some feedback and the ratio will be different but otherwise no other bad/dangerous problems? ---- I was concerned...
Here are a few stats - you will probably be able to make a much more informed guess than me.
Weight around 2500 to 3000lbs. (Rough guess)
Weight split about 50/50 as near as I can calculate
140 inch wheelbase.
18x8 inch wheels with 155/75's.
Very mild street use.
Mustang II independent...
I have a basic question regarding the installation of a manual or power steering rack on a car I am building. What are the basic parameters used to establish the installation of a power rack, obviously weight on the front wheels would be one but at what weight would a power rack be necessary...
Hi
thanks to everyone esp. Pat for that very detailed reply.
Some reasons why I get confused -
In my very limited experience with engines I noticed non-coolant manifolds getting pretty hot quickly after start up just by conduction. Won't coolant be the last thing to get to operating temp...
I thought this was a simple enough question when I first asked it but turns out I am still not sure of the answer.
Why do some carbed manifolds have coolant running through them and some don't?
Even on the same engine there can be different designs where sometimes coolant flows and sometimes...
Thanks for the replies. I will bond all metal parts that are connected with the fuel system including the filler cap.
With my truck I get a major static shock almost every time I get out of it sometimes even when it is raining. My passengers don't seem to be affected. Not sure if it is the...
HI
On a fibreglass (epoxy) body with a stainless fuel tank are there any issues regarding buildup of static that I should be aware of? The tank will be connected to the stainless filler with non-conductive fuel hose.
I am not sure wether it is best to bond everything or leave some parts...
Thank you for all your replies.
Greg, your second reply was the answer I was looking for. (Sorry my question was not well asked). Before yesterday I thought all springs had a forward bias and I wondered if there was an ideal ratio, but after looking at some more closely I did find some that...
On a leaf spring/live axle suspension why is the distance shorter at the front of the spring - from axle to eye, than the rear? I understand it has something to do with axle wrap but what exactly does the shorter distance at the front do? Also what problems would/might occur if I reversed the...
