Kev has got the right idea, although in my opinion to see 150bhp you will need some headwork and some cams with the goodies he has mentioned.Kev_G said:mantzel power box

good free flowing exhaust and you should get 150-164 bhp

Build your engine.
Then post pictures when you've finished it. Then post pictures when your pistons weld themselves to the sides of the bores or you blow your inch thick head-gasket to pieces.
Don't under-estimate how quickly a head gasket will go through. I put a cheap head gasket on my 2.25 diesel land rover and it ate through it in 2000 miles.
