Piper Cam

[stewart_2004]

Hey all I've just purchased a 2nd hand piper cam bp285HY for my 14nv engine I have a couple of questions if anyone can help me out with answers. I've been told this cam will be fine for standard hydraulic lifters will it be ok with standard springs ?

Im im gonna use the standard pulley until I get a vernier pulley do I set the timing with original marks ?

Thanks in advance.

It's more or less an ast2, which runs fine on standard timing settings and yes fine on hydraulic lifters and springs

Thanks for reply Stuart engine is standard apart from 4 branch manifold I was told if I use standard timing with cam it won't give full performance unless a vernier is fitted I'm only using car for normal road use will the pulley make much difference ?

[Stuart]

Did someone who sells pulleys say that to you?

ive seen many many of these sub 300degree cams fitted with vernier pulleys which were all pulling great power and driver while sat on oem settings...

[stewart_2004]

It was the person I got cam from who said about pulley and performance. So would I need a vernier pulley ?

[Stuart]

Imho, no. Or course it's up to you but you'll find it's on near standard settings if you do get one. Although I've seen some where the marks have been offset to make it look like you did need one lol

Should run ok without vernier. Optimum setting not quite right but still should see a difference.
lumpy tick over is probably the biggest trouble.

Right I've got cam now and about to fit it just took my dizzy off and cam has 2 holes in it but new piper cam also has a slot from side to side will this be ok.

[millworm]

Yeah, just means you can fit it to different dizzys. Will be fine

[stewart_2004]

Cheers for reply I have cam carrier off now does the cam come out seal end or dizzy end

[Royston]

Dizzy

[stewart_2004]

Cheers it feels tight does it need knocking out with rubber hammer ?

[Royston]

Have you removed the locking plate/2 bolts?

[stewart_2004]

Yeah removed the plate mate

[stewart_2004]

Just tried to fit new cam and it won't fit into the carrier also the cam seems to be slightly longer I was told it would fit my engine the cam is the BP285Hy

[Royston]

I have a Piper 285 in my Sport fitted OK, mechanical fuel pump not in the way, i.e. have you removed it, if you have one.

I would also check the length and diameters against your old cam

[stewart_2004]

The cam won't even start to go into the housing I've also noticed that the dowel for the pulley is also bigger when I put std and piper cam side by side piper is longer and the lobes don't match up the guy I got it off said it was removed from a 2.0 8v but would fit any 8v.

[Stuart]

Ahhhh, no it won't fit a small block 8v

[stewart_2004]

Stuart what engine will the cam fit ? And which one do I need for my engine ? Best put it back up for sale

[Royston]

Looks very similar, but different .......possibly 1.6/1.8/2.0 OHC 8V Vauxhall?
