the gears come with a dot punched on each, line them up together,the cam one is down to the crankshaft one and the crankshaft one is up to the cam one so that they are exactly in line with each other almost touching each other
yes
4, to 6 degrees advanced, or BTDC.
4, to 6 degrees advanced, or BTDC.
stock timing on a 400 small block Chevy 2/4 bbl engine is 4 degrees btdc. depending on how the engine is built however, i.e. rebuilt to stock or built for performance, the timing may be up to 8 degrees plus or minus tdc or more depending on valve timing and cam timing.
30 degrees and 8 before tdc
4 degrees BTDC / Before top dead center.
Many ways. Pontiac 400 has a cast aluminum timing cover, that mounts the water pump directly on it, Chevy 400 has a stamped steel timing cover, water pump mounts to the block. Pontic 400 has fuel pump on the drivers side, Chevy is on passenger side. Pontiac has a separate valley cover below the intake manifold, Chevy intake IS the valley cover. Pontiac distributor does not go through the intake manifold, Chevy does. Pontiac has 10 head bolts per side, Chevy has 17. Pontiac has long exhaust ports that bend 90 degrees from the side of the cylinder head, Chevy exhaust ports end at the face of the cylinder head. Pontiac spark plugs are above the exhaust manifolds, Chevy is below. Pontiac 400 is physically larger than the small block Chevy 400 also.
was just checking myself, but to give you an idea mine is 12 deg btdc.
There are 3 foreward gears and 1 reverse gear.
4, to 6 degrees advanced, (BTDC) initial, or 30, to 32 degrees total.
The timing mark on all 305 to 400 small block Chevrolet engines from 73 to 87 is on the hamonic balancer which is the pulley behind the crankshaft and has no belt grooves...smooth with a split line on it....that line is the timing mark.
You are probably thinking of the turbo hydro, 350. It was Chevies base automatic, after the powerglide. It had 3 gears, and was fairly tough. The turbo 400, was the heavy duty version.
