I put the longer serpentine belt back on to have AC.
I have also detuned it in search for more MPG but that was last year.
Pulled my 280H cam and 3.70 gears and went 268H and 2.75 gear.
WOW what a putz of a car.
I have 3" exhaust through straight through mufflers dumped at the ground before the rearend.
Pulled my pontoon Saturday to Tbird lake and the exhaust was loud enough that I decided this morning I would
take some of my scrap 2.5" exhaust and make some tail pipes that would exit past the rear bumper.
Lots of cutting welding and grinding later I have it finished and it seems quieter.
BUT WAIT!! That's not all.
My low end TQ feels like it gained a bunch and throttle is much snappier, but was pretty snappy before.
Years ago Well 30 years ago I tried many different exhaust systems on a 350 Olds I had.
Duals with glass packs then turbo mufflers and then single with glass pack and single with turbo and single with pancake catalytic converter out the side.
All of them went out the side but most power was had with the Cat out the side..odd how that works sometimes.
No it is not the added back pressure that makes more power it is more like scavenging and Wave tuning.
Give it what it wants.
Now I need to find or build a center console to add cup holders to this car and I will run AC duct through it and have side ports and then dump it under the seats to help
cool the back seat area.
It gets pretty cool back there now but more would not hurt.
Froze the wife saturday on the way to the lake so it works well.
