71/72 Buick Riviera Cam Help
Hello everybody,
My wife and I Bought a 1971 Buick Riviera from a chap in Nuneaton UK who imports cars from the US, He had 3 and broke 2 up to make a good one, however shelved the idea in 1992 and nothing was done until we cam along and bought it. It had an Oldsmobile 455 engine in it but it wasn't original nor in a working condition so the chap gave us a 1972 Riviera engine that we are rebuilding. Car wise the restoration is going well, have done all the chassis and suspension work and rebuilt the back brake's.
Engine wise everything has been stripped, ground and skimmed and the block has been painted (original red) however I have a question and need help in determining what I need, I am debating as to use the Camshaft I have or replace it, but when I measure it, it just does not tally up to any other measurements I can find. below are the measurements of my Cam lobes, if there are any clever people out there could you please tell me if this is within tolerance for the year and what I can upgrade to easily if possible? thank you (just to be clear it is a 1972 Buick Riviera 455 engine)
So the lift measurements I get are these...
0.418
0.356
are these okay?
Can I upgrade and if so what do I need as I am still to get valves, lifters and rods etc
Thank you anyone for your help, its greatly appreciated.
