hi dojj i had read about them being too high on other forums but there are ways around this without doing owt to the bonnet it just requires lowering the engine (made it sound easy lol) which i was going to do on my chv anyway to make it a bit easier to fit my mtx75 gearbox for clearance around the brake servo.
the engine will be getting dummy fitted before ive spent any money trying to turbo it anyway and if it doesnt look like its going to work its not a big loss as ive got it really cheap anyway and should be relativly easy to sell on
