3.8 V6 231 Engine modifications?

[CenturyAero]

I improved the power and acceleration noticeably on my 1979 231 V6 simply by switching to non ethanol clear gas.

Here it goes again. Please use the foam bats when everyone starts to beat each other.

I rather use my Lucile bat as she is awesome!

The non ethanol gas will help mileage if nothing else. It will probably improve performance slightly.

$2400 buys you CNC'd cylinder heads which flow about as well stock LS castings.

What cc are the factory iron heads? Those Champion aluminum heads is the shop Cutlassefi uses I believe for his Olds V8 builds.

Ebay turbo kit, headers and Chinese turbo(8-12 psi) then top it off with a Fitech system. Gear to 3:42-3:73 and stall to 2400-2600 rpm. Feed it E85. All else remains the same save for fuel system upgrades and exhaust, basically.

I had no idea that they started offering Chinese turbos for Buicks... Might be a nice upgrade once my stockers go.

Funny thing about the Buick V6 is how it came out squeezed in the middle. You have to get the revs up before it starts catching its power band, but the stock designs are choked off at the top end, and don't rev very high anyway.

However, these little motors weigh considerably less than a small block, and sit almost entirely behind the front axle line. That almost makes a G-body handle fairly well.

I never really thought about that but my 84 seems to like to corner better the the 83
