How is there going to be a vacuum created in the crankcase?

Overheating would be a likely cause - heat one side of a steel plate and leave the other side cool and it will pull in the dircetion of the heat.

It should just bolt on. There is a guy running carbs on a 4.6, so it's certainly doable. What part are you struggling with? By the way, the manifold in your picture isn't the twin SU one, it looks like a Holley/Weber type manifold. It's the twin SU one modified to take a 4bbl carb. The 4.6 pump doe...

Darkspeed that's amazing thank you so much. That helps immensely. With all of those dimensions we should be able to make one. I can't thank you enough. This is the one thing that's stopping me from putting the engine in at the moment. Great stuff. I've got to also thank you Gdcobra for planning to ...

I need the lower diameter, upper hole diameter and vertical height. llochins Lower OD = 47.5mm Material is 1.2mm Upper hole ID is 34mm Vertical height 32.5mm Base to the narrowest diameter of top hole 28mm Slots are 20.5mm high and 8mm wide The elipse cut out is 11mm high and 33.5 wide - which make...

Good photo's save an awful lot of speculation.

What size master and what size slave?

It will be fine - especially having an easier time in a much lighter car.

Hi guys, finally got the engine running for the 20 min cam run in. Now trying to set the timing with a strobe light, when i set the timing to 2 degrees btdc the engine runs really rough with the occasional popping. When I turn the distributor back further to what looks like 30 degrees btdc the engi...

At the end of the day the stat only really maintains the minimum engine operating temperature - once it's fully open it has no effect on the cooling capacity or effectiveness of the colling system apart from providing a flow restriction that ensures that the heads and block are at system pressure + ...

I always run Mini summer 74 degree stats in mine. Do you drill a hole in it? Depends on if I think its needed really so many different applications. Well I assumed you were talking about your Rover engine when you said "in mine". I have had quite a few and they have had different manifolds and cool...

As there is no point running an engine hotter why do you need 78 or higher? If I could find a 70 degree stat I would fit that.

Biggest issue I find with almost all engines reporting low power or lack of performace is the throttle not achieving wide open.

Then just follow the usual logical approach

Health check - compression etc.
Electrics - big fat spart in the right place - and leads on the right pots
