Camshaft specs V8S

[Marcello]

Hi,

I'm new here.
I'm the owner of V8S. I'm busy with a slight engine overhaul at the moment. THe camshaft is worn (50,000 miles...) and I asked for advise. The Piper 285 is recommended by RPI. Seems like a good choice to me. Does anybody know what the V8S engine gaines with this camshaft (44/72/72/44, 296 degr., .440 valve lift) .

Thanks,

Thanks for your replies. I already ordered the Piper 285 and I think that I will lose a little torque at the lower revs but gain power in the higher revs. With the old Cam it accellerates like hell, but it seems to be over at 5000rpm. So I guess that the original power bound is from 1500-5000rpm. I think (hope?) it will be 2000 - 6000rpm after I fitted the P285. I will let you know.
Why are you having others Cam's on your cars?Just for fun or was it necessary?

Cheers,
Marcel

Harry,
About balancing , you are right. I already brought crankshaft, clutch , pistons etc to the guy who will balance/weigh it all. For the rest I have not changed anything. Since you say that the power bound goes up to 6500rpm I'm bigin to wonder if it can get enough air...
At what mileage did you have to replace your camshaft?

rustoni said: The guys have said that if im lucky i might be able to keep the current push rods etc is this wise or should i bite the bullet and replace these as well ?

Also Marcello how does the car go now it has the piper cam and would you recommend it ?

I only changed the camshaft and the followers . The pushrods were still perfect (50K miles), so that probably woll not be an issue. It might be wise to change the Timing chain as well, because the one from my care was quite wide (?). I bought a Piper kit, including camshaft, followers, duplex timing chain for 255 GBP, ex VAT.

I'm still rebuilding the engine , so I can't tell you much more about it.

Good luck,
Marcel
