when you use the calculator on the page and enter the track at 84.9 degrees the DA is 1948'. For stock engines the corrected time is 13.567. i'm not saying that's not a good time but even with the nitrous and 4:10 it just isn't a 13.0 sec run. a cam adds 50-60hp the nitrous added 100hp.

 

Where does it say that was a nitrous run? I'll msg the guy and ask, but again I ask you to go over there and just look at the times those guys are turnin in. They have time slips and vids to back themselves up? I don't see many of those over here and I know I wouldn't even waste my time runnin my 318 sport at the track, 15's is slow no matter how you slice it.

 

I still want to see some 5.2l timeslips.

 

i can run 15's,,, but i need a 3sec head start.

A whole section devoted to swapping the LS series engine (4.8, 5.3, 5.7, 6.0) into EVERYTHING. I dont see many people banging down doors to stick a 5.2 or 5.9 into much of anything.

I wonder why that is?

 

expensive and limited aftermarket support.

 

LOL! Couldnt be farther from the truth!

 

I think he was answerin your question lol I love the 5.2/5.9 magnum engines, they are perfect in old dusters,darts etc for a nice strong street engine, but in these heavy *** trucks, they just ain't enough cubes. When you stroke and try to build them up too radical the PCM becomes the stumblin block to try and work around and usually from what i have seen on these forums and in person at disastrous results.

 

yes I was answering the question as to why the 5.2 and 5.9s aren't commonly used. The 5.2 and 5.9 blocks are solid.

 

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....
