94 GMC Sierra 5.7L 350 2wd. I have an MSD 6A Ignition and wires with MSD GM Blaster Coil and Bosch Platinum +2 Plugs. I want to get a flowmaster ehaust, but I am unsure which to get. Any ideas on any mods or any other performance mods would be appreciated.

Thanx,

Meldog

You have the TBI injection, right? I would go for a TBI spacer, definately work well.  increase in low end torque.  flowmaster 40 series if you want a real throaty sound, flowmaster 50 series delta flow if you want more of a mellow tone.  I have the 40 series and when i put on my shorty headers it mellowed it out more.  another good mod would be some kind of cold air intake (K&N F.I.P.K, air aid, etc...)

I have a 92 with the 5.7 TBI, I put the 40 series on it. It can be pretty loud when your into the throttle, but it isn't too bad at tamer RPM's. I get a lot of remarks on how good it sounds.

 

Mine is a K1500 Blazer, and I don't have exhaust tips. They just dump over the rear axle, and end without hanging down below the body. (I like a clean look)

 

These things will make the resonance a little different than what you will get from a truck. It will also sound different if you use tips, and let them go all the way out to the rear bumper.

 

The SOTP dyno can feel the increase in power a bit too. That makes it all worth it.

 

How do you like the MSD ignition/wires/coil combo? Does it make that big of a difference?

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
