my 278 pipers make for a lumpy tickover if thats what floats your boat lol
but after 2k rpm the power really does kick in right through to the rev limiter.
but youll only get the best from the cams if youve had the headwork done to get the best of them.
what im saying is if for example, if your still running a standard turbo elbow and unported head then its a waste of money just slapping a set of cams in there.
its all or nothing, half a job is useless

its still ganna make a fair difference even if you are still running the stock elbow and head ports.

would have to be inclined to disagree there, as you cant get rid of the gases fast enough due to restrictions, standard cams will be an improvement if you use vernier pulleys and know how to dial them in correctly. theres a lot more to it than just sticking a set of cams on and away you go.
it will be of some improvement but i would not bother fitting them unless your gonna do the job properly tbh

you can have valve seats recut and angled! but i just went and had the head ported and gasflowed.
theres very good people and very bad people to carry out this work, if you want it done then i can recommend someone who does it properly but are always very busy!
your looking at between 350-400 to have head ported n gasflowed and thats with you removing valves yourself and giving him just the bare head.
down to you to do all the lapping in of valves and refitting, shimming etc.
if your going for a highlift cam then you will also need stronger valve springs as the standard ones will bounce and youll end up throwing all the rockers.
so its not a cheap job. its cheaper to rebuild an entire bottom end than have head work done properly!

If you want something that is free revving then you need the bottm end lightened and balanced with a lightweight flywheel.steve963 said:
Having a head ported and gasflowed just means you can flow more volume of air NOT rev it longer or harder.
If your having the head done then get the valves triple cut and get some bronze exhaust valve guides.

Those lumpy cams will get those 15 year old chavet's nickers wet quicker than a big Mc and Fry's :shock: :lol: :lol: :lol: :lol: :lol: :lol: .
And I'm sure once you tell the lads in the pub they will be creaming their pants and running to the toilet to beat a quick one off :shock: :lol: :lol: :lol: .

To be honest you don't want to be producing all that power so far up the rev range with a standard engine, Unless you've had a rebuild with all the balancing work and matching head work I don't see the point, And I doubt very much that your engine would last long.
If you want a bit more power and keep the engine with in it's safe operating range then bung a set of HKS 264's in it.

A good engine builder will check the condition of your springs before re using them, Mine where fine for the rev range I plan on using.Jonesy said:
For a high reving engine then you would need better springs I'm sure, Their are a few options to choose from.
