Having some plans for trev over the winter... here's whats being done on the engine:

Installing the mc1 cam kit I bought
Sticking on stage3 big valve heads when they arrive smile
Ported intake to match the heads and carbon flared trumpets
Heat insulator between plenum and intake
Tin headgaskets to up the compression a bit
Might go for an EFI build if theres cash for it

Its fully decatted now and with a lightened flywheel, should be nice and snappy when all mods are done. When all is done and efi working good, might consider the turbo some time in 2014...

Just wondering if I should do a couple of other mods while at it... like regasketing waterpump/oilpump etc... any tips here?

Whats your plan??

Mine is to put my 4.6 back together, (wheels, brakes, suspension & seats) give it a good clean up and sell it!

BTW, sounds like a good plan what you,re doing at the moment Ole.

How many miles has the engine done?

If it's a high mileage engine it may be worth new oil and water pumps while you're there.

It's done 51k miles now, cam change feels right... Its serpentine type oil pump, dunno if this is better than the earlier type?

Serp is better.

At that mileage the oil pump will be fine and if the water pump shows no signs of leak or spindle wear, might as well leave that too.

Hello my old friend again from far.

Some parts of your project are contraproductive with target - projects for 2014.
With a thin steel head gasket youl will grow up the compression which will be to much
for a later turbo/commpressor.

I work for a compareable project at moment.

I am going for full decat, then get the induction/inlet matched to the potential of the 5.3 V8 Dev engine, then remap Lucas or change that out as well.

Hopefully business will be good in the new year to pay for this lot!

Hey buddy, I sort of know this. I have a normal gasket here if i go turbo...

But how do i know what comp i have now? 9,35 like the 4.6 or 9,8 because the 3,9 has flat pistons? I am confus...

If you are unsure of your compression ratio and it is important, you can measure it.

It is a complicated process that someone else can explain.

Carpets out ,going to see if I can get the MGB one`s to fit laugh

Already got the battery in the boot so the next job is the fuse box to be fitted behind the passenger seat and a new "loom" and get it leaned off in some cruise areas. Runs a bit rich around 13.9 up to 70mph.on low load.

Still got the crazy speedo problem so that needs sorting .

13.9 is not rich up to what I have just seen

Up to 55mph it`s 13.9 then jumps to 14.3 then at 70mph to 80 above it`s 16afr.Maybe it`s rich because in lower gears at lower speeds it in the same window to stop shunting .

At that speed I would expect at least 14.7

You could be in fourth gear at 30mph so it needs to be a bit rich to iron the shunting out ,it will sit in the same window in fith at a higher speed, so will be rich in that area . Why can`t it jump on another VE table to counteract this.
