Thanks for all the answers
Bored and stroked FE as far as I am aware - I will getting hold of it in a couple of weeks so I'll post some pics then if you like. (the spec was a copy/paste from Huddart's spec sheet so it should be an FE)
Its getting mated up to a Porsche 930 transaxle via an adaptor plate the chassis people are developing for me
Edit - Stentor I've just checked the spec sheet again "FE Ford @ 452c.i. (7.4Litre) 500H.P." sorry for the confusion.
