During my strip down of my Jan 2000 built Tuscan, I discovered these marks on the followers and Cam:

After much deliberation about who to use and what to have done, I ended decided to put my faith and money with Dom at Powers Performance. Dom convinced me that the 4.3 was the way forward, so mid August 2012 I took the block & head for reconditioning and the gearbox/clutch for a check.
I've asked Dom to take a video/picture diary of the rebuild to add to my records, hence this post, which should be informative/interesting.
My Tuscan is a Cat d and for some reason I've always had the gut feeling that the car was deliberately crashed (insurance job). My suspicions may have been proven right. See the video of the end float play. (70 thou!)

This play, the knackered water pump combined with lots of metal filings coming out of the oil reservoir when being flushed out, shouts to me that the engine was on the way out when it the car was crashed.
Flywheel is rather rusty. It might be possible to salvage?? And here's a video of the new liners being bored out to 4.3litres.

I thought the Power 4.3 engine just had a longer stroke?I was under the impression they only bored out the 4.5?
By the way, thanks for posting all this info, it's really useful and interesting. I'm about 6 months behind you, and trying to work out which direction I want to go in on the engine upgrade.

My regret is not getting a lightened flywheel at my rebuild - additional costs stacked up on top and I was at the limit of my budget. If you have the option get it done. http://youtu.be/P6p21AMlhjM

No worries. Someone somewhere will always have a use for this kind of info. Its what the web was created for.I was under the impression they only bored out the 4.5?

I'm guessing the liners are for all applications, staring with the 4 litre, and they need to be bored/honed to get the perfect diameter. I understand that the crank is new giving the increased throw and + 0.3 litres.

No, apparently the 4.4 is not a stroker engine.
Dave is firm in his belief that this is not the way to go.
What figures are they achieving?Dave is firm in his belief that this is not the way to go.
It would be good if someone made a spreadsheet showing the various configurations of engine set-up and power achieved from the different companies.

There is a dedicated thread where people have entered in their rolling road measurements for the speed 6, but I'm damned if I can find it! I'm sure someone will be along shortly with the link!It would be good if someone made a spreadsheet showing the various configurations of engine set-up and power achieved from the different companies.
