My bad. I thought you were refering to the ls motors. People are giving away aftermarket stuff for these ls motors.

i didn't see many 5.2 time slips, most of the times are for 2nd gen rams but here's a 13.9 sec one on a 96 ram 5.9. it has exhaust, intake, PCM, gearing and sticky tires but still nothing major done to it.

I dont want to change the subject, but i know that the PCM becomes a major problem when you get into more serious engine work with these trucks, but what would be the disadvantage to eliminating the PCM? That would get rid of that problem. I know there are obvious disadvantages like no more fuel injection, but anyone who has been around an older carbureted engine, knows that carburetors can be tuned very well and can match or exceed the performance of fuel injection with very little sacrifice of reliability. So other than the obvious reasons, what would be big disadvantage of removing the PCM?
I think a worked 360 or 318 with a carb would eat a 5.3 with equivalent mods....

The atomization and fuel distribution of EFI is light years ahead of carbs, plain and simple. No "can" be superior it IS superior. The more of these threads I read, the more it looks like there are a TON of people on these forums giving advice that truly have no clue wtf they are talking about.

You are incorrect. Even with the old Bosch systems in early air-cooled VW's, Porsches, Audis, and others, the FI system can be tuned for efficiency per cylinder. That's nothing a carb can do.

Some racing applications prefer carbs. based on simplicity and cost or intake design. i also never said that a carb can be tuned for efficiency per cylinder so i'm not sure where you got that. i simply found your "controlled fuel leak" comment entertaining. injectors "leak" fuel also.

I wasnt trying to start an arguement. It makes me laugh how some guys on this forum get so into trying to force their opinions on everyone to prove theyre correct about an issue... BUT I was simply throwing that out there as a suggestion to overcome the PCM probelms. Take it or leave it. Would it not stand to reason that: since the PCM creates such a problem, and there is only so much you can do with it, that you could make more power with a carbureted engine with no PCM than you could with the fuel injection and PCM in place? (at least on these trucks).
I know FI is superior, if it wasnt it wouldnt be on every new car since 1983-ish. But if you want the power, you gotta do something to get around the computer...
