Chev 305 appeared in the "bad years" - small bore, long stoke
to keep the left-wing people happy in the 80's with shitty engines,
when Al Gore's wife tried to ban Rock & Roll (seriously), like
something from the script of a stupid TV movie with Kevin Bacon.

I think you're referring to the completely different Chev [b]302[/b],
which had the 4.0 inch bore of the 327/350 but the short 3.0
inch stroke crankshaft of the 283. Famously used in the 60's Z/28
which was a Trans Am series car. Highly modified, of course. They
acid-dipped the body to make it super light weight.
[quote]When the journal size increased to the standard large-journal size, the crankshaft for the 302 was specially built of tufftride-hardened forged 1053-steel and fitted with a high-rpm 8.00 in (203.20 mm) diameter harmonic balancer.
It had a 3/4-length semi-circular windage tray, heat-treated, magnafluxed, shot-peened forged 1038-steel 'pink' connecting rods, floating-pin in `69, forged-aluminum pistons with higher scuff-resistance and better sealing single-moly rings.
Its solid-lifter cam, known as the "30-30 Duntov" cam named after its 0.030 in (0.76 mm)/0.030 in hot intake/exhaust valve-lash and Zora Arkus-Duntov (the first Duntov cam was the 0.012 in (0.30 mm)/0.018 in (0.46 mm) 1957 grind known as the '097, which referred to the last three digits of the casting number) the "Father of the Corvette", was also used in the 1964-1965 carbureted 327/365 and fuel injected 327/375 engines.
It used the '202' 2.02 in (51.31 mm)/1.60 in (40.64 mm) valve diameter high-performance 327 double-hump `461 heads, pushrod guide plates, hardened 'blue-stripe' pushrods, edge-orifice lifters to keep more valvetrain oil in the crankcase for high-rpm lubrication, and stiffer valvesprings. In 1967, a new design high-rise cast-aluminum dual-plane intake manifold with larger smoother turn runners was introduced for the Z/28
In 1969, the 302 shared the finned cast-aluminum valve covers with the LT-1 350 Corvette engine. Conservatively rated at 290 hp (SAE gross) at 5800 rpm and 290 lbâ‹…ft at 4800, [b]actual output with its production 11:1 compression ratio was around 376 hp[/b] with 1.625 in primary x 3.00 in collector Sanderson tubular headers that came in the trunk when ordered with a 1967 Z/28, and associated carburetor main jet and ignition timing tuning[citation needed].
In 1968, the last year for factory headers, they had 1.750 in primaries x 3.00 in collectors. A stock 1968 Z/28 with the close-ratio transmission, optional transistorized-ignition and 4.88 gear, fitted with little more than the factory cowl plenum cold-air hood induction and headers, was capable of running [b]12.9 second/108 mph (174 km/h) 1/4-mile times on street tires[/b].[/quote]
and what shitty tires they were. Skinny bias-ply IIRC. You wouldn't put them
on your lawn mower, today.
Factory headers in the trunk. The good old days, back when my Uncle Pete
was the Chev/Olds/Cadillac dealer in King City, north of Toronto.
