I had a brain fart earlier, I was going to say splitfires too, but I couldn't think of the name. i had split fires in my 76 Chevy and didn't notice any difference. 40.00 for plugs, I sure thought I would have seen something other than an empty wallet.

try all those supposed octane boosters you can buy at crappyzone and walmart. see if they actually do anything at all. if you got the money see just how much an auto tranny robs over a manual??????? just throwin out anything i can think of.

Not sure if anyone has said spark plugs yet...Standard,Platinum,Double Platinum,Iridium or the $25 a piece Pulstar Pulse Plug..Havnt sold a set of those yet!!!
I saw throttle body spacers, but no one mentioned the upper to lower intake spacer.
I have seen on other websites that some people have removed the engine coolant flow from the throttle body. I suppose it is to reduce the temperature on the air charge.

I thought the purpose of the coolant hoses on the throttle body was supposed to help the truck warm up quicker in the winter and even keep the throttle body etc from icing up in colder climates. I don't know if it can help keep it cool when its hot or not. My thought is that it was designed to be that way, so I don't think disconnecting it is going to make the truck run better.
As far as spark plugs go. I don't see how any of the split fire type or bosch platinums with the multi spark tip are going to produce more power when everyone says their truck doesn't run as good with them. It would be interesting to see if any of them do make more power though.

I only saw the throttle body heater hose removal on the small car websites, not sure what the affect will end up.
I also didnt see the airfilter modifications other than CAI, like the difference between OEM paper filter and the K&N drop-in/Fram airhog(if it is still around).

Yeah, removing the coolant flow from the throttle body is pointless. It's not like the air is flowing through a mini radiator inside the throttle body. Not to mention, the throttle body is smack dab on top of the engine where it's gonna get hot anyway. The coolant would at least keep it down to no more than 195ºF, which the incoming air would help with also.
Alot of guys remove the TB hose because they start to leak or they just want to clean up stuff under the hood . If you don't live in a cold climate you don't need it , the TB should run cooler with out it but i don't now if it would help performance wise ??? Lew
I have unscientifically "tested" some of these things over the years swapping parts and trying these simple things to see if they make any difference at the SOTP dyno. Nothing to do with the TB has any effect on the truck motors, on a HO there are benefits to opening up the upper to accept a larger TB but that's because it works so much better at rpm and the HO intake is so much smaller than the truck setup. With the engine at operating temp even fairy large changes in ambient air temp have almost no effect at all on air temp inside the motor, there's just so much heat energy contained in that massive aluminum intake the incoming charge is instantly heated. The way the EEC-4 computer works also rules out benefits from higher octane fuel, MSD style ignitions and Hi tech spark plugs. The computer is set to a base ignition profile and all it can do is take out timing if detonation is sensed(on knock sensor equipped motors). Unlike the newer EEC systems it isn't programmed to constantly advance timing to the limit of detonation so you won't see any benefits from these things unless you manually advance the base timing more.

I use the TB coolant lines are a way to bleed air out of the cooling system, other than that, they are another "$$$ problem" down the road.

i would like to see a cam swap (biggest one for speed density) and all of the other things you can do to get more air in with fuel injection different manifold injectors throttlebody air intake blah blah blah vs. a rpm airgap intake manifold with a cam that is reasonably larger than the speed density cam with more duration and lift than speed density can handle and a 750 holley if it's a 351 your doing testing to or a 650cfm holley if it's a 5.0
settle the debate, and don't be scared to wind the piss out of the motor with the huge cam in it to get that extra little bit of h/p hiding in the top end past 6k
