Thread: stroking a 3.5 motor

Er, the liners can and do move up.
The fire ring of the gasket is outside the liner so it can move up until it hits the head. On a steel gasket that is about 20thou.
The theory in "Tuning Rover V8s"' is That when the liners are put in a hot block they sometimes do not sit fully on the ledge. This gives them more room to move.

I also cant see how a liner can move UP because of the head sitting on top.
I have heard rumors about liner shift on these engines before and would welcome some comments based on my observations.

G'day Mark,
I had a 3500 rebored with two new liners fitted some years ago. After
10 000km it started ticking, which developed into a bucketful of rattles fairly quickly. The engine reconditioner and I (like you) couldn't see how the new liners could move. The short answer seems to be that the original liners did not have the top-hat and it is probably they that have moved. I still haven't had the nerve to strip it down and check
Cheers Chazza

So put in an English made copy of an obsolete Detroit aluminium lump, redesigned by Rover so they could make it on their 1928 vintage engine plant and machine shop.

The difference in weight would barely be that of a steel bullbar.

Is the adaptor for an LT85 the same as the adaptor to an LT95?
In other words, would it bolt up to an LT95?

I've been thinking about replacing my 3.9 with a second hand 4.6 as it is the easiest replacement. do any of you have any idea what the 4.6 is like?
