Camshaft advice for 1275 engine

Post by tysonn »

My car has a midget 1275 engine with a hot cam(probably Piper if the sticker on the rocker cover can be believed but I'm unsure).This is what was fitted when I bought the car as an unfinished project.To be frank I don't like it.I aren't a boy racer(very far from it)and although it goes like hell when its "on cam" I would prefer something more sedate and a bit quieter.Can someone please advise what cam to buy to make it as "standard" as possible.I might even explore the logistics of swapping this setup for a 1098 engine.Its wasted on me.

Personally for the requirement you desire I would put a standard 1275cc MG Midget camshaft back into the engine and sell the cam currently fitted :D
If you go for a 1098cc engine try and find one with 2" mains. Much more durable.

If I was purchasing a 1275cc Midget camshaft I would rather go for a good S/H one rather than a re-profiled one as you never know what profile the re-profiling has been done too unless you know the company that did the re-profiling.
Standard cams for the 1275cc Midget and which to look out for are:-
AEG 577
AEG 323
AEG 538
Also fitted to the Marina 1.3
All with 1/2" wide lobes.

You will be very disappointed with a 'standard' cam after running what I assume is a 544/286 profile cam. If possible - find an MG Metro cam which was developed for the 1275 engine - up to 6000 rpm. Not many about these days - a near equivalent is a 256 camshaft which will run nicely. I too would not buy that 'reprofiled' camshaft...who knows what it is!

I would either go for a standard cam, or something like the Piper HR255 cam which gives more gains in the low-mid revs range

That cam runs very high lift with 'soft' timing. Note they also advise 'high lift' rockers to be used with it :roll: .....these are not included and are extremely expensive.... They also forget to mention that a duplex chain will be required, although your engine should have that already if it has a hard cam at the moment. If you are willing to spend that amount of hard-earned......good luck with it! It would not be my choice......

Problem is - it may be exactly what you have, or very similar to what's in your engine at the moment. Keep looking for an MG cam - or a 255/6 at the right price. It is almost certainly an engine out job to change the cam..... Only hope is if you pull out your cam and it is a peg drive - then you could refit another cam with the same drive arrangement. Cam followers held up with 8 magnet sticks of course..
