piper 255 cam

[plasticpig72]

i wondered if someone has tried a Piper 255 cam (high torque i think) in their car.
I am finding the Piper 285 fitted at the moment very tiring for pleasure drives. Keeping the revs above 2200 rpm on Sunday drives a pain in the butt. I don't intend to do circuit driving and i would like something more agreable to drive with swmbo as passenger.
my car is a 1600m

[plasticpig72]

the 285 splutters and just about starts to operate from 2200rpm.
Looking at pipers own cam data the 285 operates from 2000rpm to 6000rpm and is good for track days.
My Lotus Elan Sprint pulls smoothly from 1000rpm.
My 1600M splutters untill it reaches 2200rpm and then just starts to think about delivering the goods which is no good for me.
My boy racer days are in the past and i don't drive round the Goodwood Track anymore.
So has someone fitted a Piper 255 to tow a caravan behind their TVR or for retired peoples Sunday drive to the pub to talk about the good old days

well that settles it Piper 255 or if price is better Kent 234.
Many thanks chaps

i have just removed the camshaft from the spare engine block which came with my 1600M. It is supposed to be the original one from when the car was made. The markings on the camshaft are IM-6250-DA and in another place RB4 and ford. I have measured the profiles heal to toe and they are just under 33mm (32.85mm to 32.98mm). Is this the ref n° for GT Capri cams
many thanks if someone can help to identify the camshaft please

the engine runs very Well and clean but under 2200rpm it is very flat(crap)piper 285.
imho it is just a case of changing the cam for a normal relaxed road cam such as Piper 255 or Kent Cams X/flow "GT" CAMOHVGT from Burton. The engine is very solid and for sure it's not necessary to change the complet engine but only the cam.
With a milder cam it will also pass the polution contrôle for the mot much easier.

hi Frank,
you are 100% right.
I think i will put a milder cam maybe Kent CAMOHVGT from Burton. The head has been flowed a little but not too radical about stage 1+ a little. Carbs twin 40 dcoe's.Duplex timing chain balanced and lightened. Dizzy Lucas same as Lotus Elan/ Cooper S no vacuum advance.
With the Piper 285 keeping it above 2200rpm for me is not relaxed driving.
If someone wants to buy it for track days and boy racing it's on the market for
12000 €uros

If you don't want to turn the engine over small magnets from a toy shop or e bay glued to strings works for me !!

now that sounds very interresting indeed
I'll play with my spare block and followers

just placed an order for a CAMOHVGT from Burton, so maybe i can fit it in a couple of weeks.
I'll try the magnet trick for the followers and keep engine in car.
Since the engine was rebuilt with a piper 285/2 cam it has only done max 500 miles, so i will not change the followers which are new.

in the past i have used STP oil additive with good results when rebuilding engines.
