My question is how far can you upright a 4k before you need to do any other alterations such as adjusting the oil pick up,sump,etc.

Are you looking to do a half upright? :)

Not much, if at all. The stock sump pickup can be a little prone to brief starving as it is, uprighting will only compound that.

 

Why do you want to upright anyway?

Fitting the engine in another car and the carb almost fouls on the suspension and the ex. manifold could use a little more room to fit the pipes so thought that if I upright it about half way it would give me clearance.

Hmm. Simply put, it you're going to the effort to half upright it, you might as well fully upright it.

What's it going in?

A morris minor that has hydraulic dampers as part of the suspension and they are mounted in the engine bay

Once you upright the engine wouldnt you need a custom exhaust manifold anyway?

Why not just make one to work with the room you have, same with an inlet manifold? Or is that not an option?

Just get an A12 out of a Datsun, that's the usual Morrie substitute and it is already upright.

 

What are you going to do about the carb angle?? They will end up at a funny angle that will have the fuel in half the bowl.

The 4k will fit in a minor,it is done quite often but yes,the datsun is the more common conversion.It will fit mounted at its proper angle but it just makes the transition of the exhaust from the manifold very tight,often people fit custom made extractors but I was looking for an easy out,how lazy of me!!

lots of room Pete ...

certainly is plenty of room if you are going to fab yourself custom extractors etc. but if you try to use the original ex. manifold the angles the engine pipe has to be to line up with the original manifold outlet are quite extreme,I know this because I already have a 4k set up in another minor and that was my main issue.Just thought that by uprighting a little I could reduce the angle and use an original exhaust.

By the way,nice pic,I like how you set the alternator up.

trying to use the existing exhaust manifold is doomed for failure

dammit every 4K should have come out like that!

 

Alty on that side, beside the battery (sitting on the chassis) & upright!

Is that your build Frosty??

Would really like to see a photo of the bottom mount.
