yeah no chrysler started OHV production in 1951

on the left is a flathead engine also called an L-Head, on the right is an OHV engine

OHV standfs for overhead valve

the problem with flatheads was despite the lower cost of production and simplicity of design it was limited in horsepower and efficiency

because the fuel mixture had to go up to the side and into the cylinder efficiency was horrible and compression was extremely low

leading to gas guzzling tendencies and higher emissions alongside slow speeds and low horsepower, which was a problem in the post war economy due to the trend in larger heavier vehicles for growing family households

the T valve flatheads had a particularly bad habbit of emitting high amounts of NOS gas due to insufficient combustion in the cylinder

during the horsepower wars in the mid 50s to the early 70s engines in the 60s started going through some radical developments due to chrysler's new 426 hemi in 1964

places like ford and gm started making their own performance engines in the mid 60s to early 70s

ford came out with its SOHC version of their 472 FE V8 in late 1964

it was the first successful Single Overhead Camshaft engine produced

and it put out 657 gross horsepower when fitted with dual quads

that vastly overshadowed chryslers 426 hemi that only plut out 425 HP at max

oldsmobile started experimenting with DOHC or double overhead camshaft engines in the late 60s with the W43 engine

but the project was shut down due to the damned government emissions regulations and fuel crisis

btw the ford SOHC engine was dubbed the 472 Cammer to differentiate it from their OHV counterparts

this is the difference in said designs

the latter two are more powerful due to the increase of valves

SOHC and DOHC have two intake and two exaust valves

OHV has only one of each

DOHC has a mechanical advantage over SOHC

and thats because if one camshaft rockers break in one cylinder....

there are still the other set pof valves that keeps the cylinder functioning

almost all vehicles nowdays are powered by a DOHC engine

sorry if i'm flooding the chat with all this technical stuff 😅

my dad and grandpa worked for chrysler before the plant shut down

although i find flatheads to be one of the coolest things to work on

lots of aftermarket parts and tons of modifications that can be done to maximize horsepower

with a hilborn injection system you can get 300 horsepower out of a flathead

some with superchangers and NOS systems can reach 400 horsepower

So i have a custom transmission concept.... 5 speed with an external overdrive, you then essentially have a double overdrive transmission. If it's gonna be a column shifter it should be like the dog leg 5 on the floor transmissions with reverse over first, this is ideal for road racing too. if 5th gear is 0.71:1 ratio then the external overdrive gear ratio should be 0.59 to 0.62. You get two advantages with this configuration, 1. you can split all 5 gears in overdrive with 5-Over being the fastest ratio and essentially an Overdrive within Overdrive, 2. it also means less wear and tear on the engine than a conventional 5 speed. The only disadvantage is the fact it may not be as fast as a 6 speed but its pretty damn close.

@everyone yang gang vs Ben Shapiro is today

@Indigo Lucifer not sure if you know what transmission clutches are

You have holding and driving clutches

You have clutches inside and outside the input drum. But your dual overdrive wouldnt do much

so much for "based gook"

cucks out for the kike
