engine and dry sump
is there any way to tell if an engine will need to be fitted with a dry sump, before sticking it in a 7 style car, or is there a list anywere of
engines that can be used without dry sumping

There's no way of telling Im afraid although an experienced engine builder may be able to make a qualified guess given the sump design etc.
There's not even a definitive answer for each engine as some of it depends on things like the type of use (road / trackday / racing etc), with
how much grip (tyres / downforce etc), and which orientation the engine is installed.
Having said that, assuming "Normal" use of road / track driving on road legal sticky rubber (Yoko 48s / R888s etc), then there's
only a couple engines that needed dry sumping, off the top of my head, which are the the Blackbird and debatably the busa.

Depends on how fast you go round corners. In my TR7 the V8 had no problem with oil pressure - installed in a lower chassis with sticky tyres it
suffers from oil surge badly. Beware the cost though its not just a pump and sump you have all the pipes and reservoir not to mention exorbantly
priced fittings to boot.

If you post up a list of engines you're considering, I'm sure we (LB members) could give you some advice.

i m in the process of building a MNR RTIB with a bussa but can make up my mind wheather to dry sump it, i ve been speaking to different people some
say yes and some say running a sump baffle is fine
i think if you ve got the funds ie 1K quid then do it but if not go with the baffled sump and take it easy round corners lol
i will prob dry sump it once i ve got all the other things done and get it through its SVA but in the mean time i will just run a sump baffle, also
MNR advised that their bussa demonstraighter just runs a baffle
cheers
