motor difference

What the difference bettew a factory intercooled truck and a factory non intercooled truck? is it the injection pump? How come when you put a set of PODs in a factory IC truck you can get around 30hp more than when you put the same injectors in a non IC truck? What would it take to make the non IC truck to make the same power as a IC truck?

The Non IC truck can have more HP for allot cheaper then the IC trucks. The factory injectors in a Non IC truck are larger then the IC trucks and only slightly smaller then the Stock Non IC injector and the non IC injectors can support 300+ hp with no issues. Not to mention the holes are 9mm for the non IC as apposed to the IC 7mm and the heads on the Non IC were prone to cracking between the injector bore and the valve seat. The other is I believe the delivery valves in the Non IC pump are larger. The other is the KSB works the opposite of the IC truck.

He covered it all ^

Piston bowl is different between non i/c and i/c....

and i've even heard over on 1stgen.org that the non i/c motor had a thicker block or something because it wasn't designed for a pickup, it was made for industrial use. 91.5-93 the blocks were thinner because they were for the pickups. THIS IS WHAT I HEARD.

also what iv heard is that the camshaft is more like a marine cam, which is a bit more agressive
i think the injector lines are bigger aswell

If I am putting this the right way the KSB is like a electric choke on a carborated veh. It either gives more or less fuel depending on the set up. I am still not 100% on the functionality on them but I'm sure someone who is will chime in with the correct answer.

The ksb will advance the timing depending on the temp, so yes it's like choke but instead of making the fuel mixture richer it adjust the timing

the reason you get more HP out of an i/c model than a non i/c when using POD's all comes down to comparison. POD's are a 4x.014 injector (4 holes, .014" each). stock non i/c injectors are 4x.012's (4 holes, .012" each) and stock i/c injectors are 6x.009's (6 holes, .009" each). as for the KBS. it is simply a cold start aid which advances timing at start up and cold temperatures. the non i/c KSB is a wax motor and when there is no power supplied, it is advanced. inversely, when there is power supplied, it runs at stock timing. the i/c KSB is the complete opposite. when there is no power supplied, it runs at stock timing and when there is power supplied, it is advanced. the KSB will also advance timing at higher RPM's due to increased case pressure within the pump housing. the delivery valves in the non i/c pumps are slightly larger than the i/c pump delivery valves. i've never heard of the non i/c blocks having a thicker casting than the i/c blocks. the only block i've ever heard of having a thicker casting is a storm block. overall weight increases of course. what else would you like to know?

If someone was running a non ic truck could they put the ksb on a toggel switch and add hp by taking the voltage away? and turning back to stock when not needed? maybe if they go to the dyno they could turn it on and have more hp than stock?

Yes, but the wax motor is kinda slow.

Too clarify this a bit... the injector bore is larger on the non i/c. Less confusion for noobs I think.

it probably wouldn't be a noticeable difference, but yes you could wire a toggle switch to it, but the wax motor takes somewhere around 5 mins to "switch modes". you're better off to just pull the wire from the terminal for whenever you wanna run advanced. not recommended for long periods of time though. maybe only in a dyno or a drag run.

yes, if i didn't mention it before. non i/c injector bores are 9mm and i/c injector bores are 7mm

Could a guy take non ic injectors and put them in a ic motor and get a slight incresse in hp?

no....

the injector bore in NON i/c trucks is 9mm and I/c is 7mm so the non i/c injectors are physically TOO big to fit in the head on an i/c truck.

but it can work the other way around...they make adapters to put I/C injectors into Non i/c heads...almost all 1st gen perf. injectors are 7mm and require adapters to put in a non i/c truck...

Clear as mud ?
