Hi, i need a new cam for my 454 1972 engine, and Im completely lost... There are hydraulic ones solid flat tappet ones?? COMP cams is what JEGS recomend me.. my garage recomends the Standard one... but what do you tech guys recomend??? If I can get a bit more of power im always happy.. If its not worth it etc.. just let me know...

This is what my garage ask me to order:

Gasket set for oval port heads.
TIMING CHAIN (while we are at it)
TIMING COVER GASKET
CRANK OIL SEAL (IN TIMING COVER)
SET OF HYDROLIC TAPPETS
CAM SHAFT...

This is what JEGS recomend me.

The following is a list of part numbers I would recommend for your 454 Chevy engine,

249-CL11-242-3 Comp Cams Cam & Lifter Set
249-911-16 Comp Cams Valve Springs
249-2110 Timing Set
720-4405 Cam Change gasket set for oval port heads.

you need to define what you want as far as drivability and power requirements.
I can't imagine putting a stock spec cam back in.

I'd recommend a Competition Cams 268H grind. You can get one in a kit form that includes new springs and hydraulic lifters. All you'll need in the way of gaskets is an oval port intake manifold gasket set, a timing cover gasket, and a pan gasket. And a new timing chain set (comes with a new chain and both sprockets). Solid tappet cams are rarely sold anymore as the hydraulic cams are so good.

A "roller" cam uses lifters that have a roller on the bottom that rolls on the camshaft whereas a "flat tappet" cam uses lifters that are flat on the bottom and slide on the camshaft. The roller lifters are quite expensive and you can figure a roller cam and lifters will cost you somewhere between $600 and $700. About 2-1/2 times as much as a "flat tappet" cam and lifters. A flat tappet cam will usually last as long as the engine but a roller cam will last virtually forever.

flat tappet cams won't last as long as they used to due to oil formulations being changed

ZDDP levels ( I think that's the name ) is being lowered
