I wish an aftermarket intake manifold with accompanying intake tube was available for this engine. I'd swap it.

Fun tidbit... the offset was done for a longer runner to increase torque production for pickup application most likely. Think the old TPI intakes. If one wanted a swap, the camaro/other 3.6 intakes are a standard front mount throttle body. Then you just need to figure out the plumbing. Being the architecture is identical they should bolt on. Looks like it should anyway. You may lose a little low range power...

Edelbrock makes one, but it comes with an extra pulley.

Why can't things be like my first car I ever owned... A genuine 1971 Plymouth Satellite with the 318 V8....

For perspective, this can also read as, "Why can't things be like they were 53 years ago?"

My first vehicle split the gap, technology-wise, between your Plymouth and our current trucks. A '99 S10 Blazer. 180HP 4.3L OHV V6. With a few tweaks (muffler, air filter, e-fan, underdrive pulley) it made decent power and got about the same mixed fuel economy as my current Colorado. Same body-on-frame, RWD construction, comparable weight (my Colorado is about 200lbs more). Except now the V6 is capable of about 70% more horsepower. Apart from the muffler, the other tweaks I made have already been done.

Efficiency and power are namely improved by Variable Valve Timing (common since the 1980s), higher compression made possible on 87 octane with direct injection (common since the early 2000s), and electronic accessory drives for power steering & cooling.

Apart from replacing some wear items and failed sensors that your OBDII codes will indicate, there's not much to mess with under the hood.

The engine cover was designed to reduce engine noise according to GM engineers in early Youtube videos with the ZR2 development team.

I've handled three different oem intake manifolds, they are cast as two pieces then glued together. All had a mismatch in the runners about 1.5" from the end of the runners, a 1/8th" plus lip that causes turbulence in the air flow. I bought a new intake from GM and ported it, cleaning up the mismatch in the runners and reducing the size of the air vane behind the TB. No effort was made at increasing the size of the ports. I just worked at smoothing the surface of the ports. This resulted in a noticeable increase in throttle response and low rpm torque. YMMV.

Well back when I had my TransAm WS6... That would of been a something I would of done
I was going to get teh GM Performance Kit that would of made my TransAm LS1 into a LS6

I was a working auto mechanic in the 1960's and fully remember the cavernous engine compartments and simple engines the original poster so wishes for. However, I also remember the need to do points, condensor, rotor, spark plug wires and valve adjustment every ten thousand miles, oil and filter change (if it had an oil filter, many did not) every two to three thousand and adjust or replace the drum brakes as needed, which was frequently. Oh, don't forget exhaust systems - they were rusted junk within a few years of installation. Shocks lasted a few years and maybe fifteen or twenty thousand miles.

Modern cars may be a bit more difficult to work on but you need to work on them so seldom that it balances out to a much easier situation now. Between superior materials, computer controlled functions and superior lubrication, most modern vehicles don't need much real maintenance until well over a hundred thousand. Change fluids and filters as scheduled and replace brake pads and wiper rubbers as they get used up and you are good for a long time and many miles.

Don't forget all the modern safety features as well - I used my employer's wrecker to pull apart many wrecks to the point where the mangled occupants could be pried out. Modern vehicles provide waaaayyyyyyy more surviveable situations than the old crocks. That said, I love the old crocks and am keeping a couple of them alive for short drives on quiet country roads. For real driving on modern high speed roads, I will use a modern vehicle.

enginerz need jobs but EPA makes them design stuff that gets more than 10 MPG with 8000 sensors, testing the air quality/water temp/exhaust temp/ intake temp/driver temp and on and on and on, reporting to a computer (?) which is sending ALL this gathered info to the Mother Ship, located who knows where, giving u a whopping 18 MPG combined
