There needs to be some Hemi guys chime in on this thread. It seems everyone thinks a stock 5.3 can take a stock hemi. In my experience I havent seen it that way. Hemi guys tell your side in that thread. Later.

 

I have only seen a few stock hemis run at the track and on the streets but from the numbers and times that i have seen, i believe that a stock hemi will beat a 5.3 most of the time given that the trucks are of similar style(ec, sb, 2wd/4 etc). I saw a stock 2wd qcab hemi run 16.0 @ 85 and a single cab 2wd hemi run 15.5 @ 88 if that helps any. At the same track as the single cab hemi, there was a 2wd single cab 5.3 running 15.7/8 @ 86.

 

Im not a dodge guy but the hemi would win 99% of the time most of the guys on here are biased.

 

Having owned both I would say Dodge 99% when it is apples-apples. The GM's respond better to basic mods and have more potential, at least for now. Someday we'll get a full computer tuning kit and life should be better.

I made a phone call today. I don't know if you've gotten wind of what's going on with my truck right now or not (i cant say, had to sign nondisclosure) but soon I'll have to have a tune. If it doesn't come back with enuff tune I'm seriously considering the Megasquirt. Did a lot of reading and made taht phone call and it seems like it could be the answer. We may see

 

I've owned both and my 04 4x2 Hemi Ram QC would have beaten my 00 4x2 5.3L EC Silverado, no question. The Silverado had 3.73 gears and 255/70R16 tires and the Hemi has 3.92 gears and came with (don't have them now) 275/60R20's. The 20's are alot heavier and taller which cancels out the lower rearend gear ratio. Didn't have a G-tech back the so I used a stop watch, the Silverado did 0-60 dead stock in an average of 7.35 seconds, the Ram did it in 6.75 dead stock. Both would have produced slower times now that I have a G-tech and realize my stop watch times were to fast but, it did show me that the Ram was faster.

Colt, I will be watching with open eyes/ears for your progress. I looked heavily into the MS unit when I had the turbo and liked it a lot, mainly for the price. Downside was that it could not control timing unless the Furd EDIS crank pickup was used ( like the Hot Rod magazine test ). I understand that MS was going to figure out how to use the GM/DC crank pickup and coil-on-plug signals which would then allow control of spark and timing. This would put it above the SMT6 unit for price and adjustability.
Keep on truckin' and posting results!

 

Yeah the hemi's gonna take the 5.3L, but they should really be putting the hemi against some ppl that have stock 6.0 swapped in or the 5.7ls1 engine. The 5.2 need to be compared to the 5.3 and the 4.7 compared to the 4.8. I think if you take each motor and put in a 2wd rcsb truck that the chevrolet will come out on top on all of them in stock form. Yes i know that's not what the thread was saying, but that IMO is how they should be compared

 

Agreed, the DC 4.7L motor is nice but the GM 4.8L will smoke it. Likewise the "LS1" motor I built would eat my Hemi alive ( although it is 5.7L vs 6.3L ).

 

You should match your 6.3 to a 6.1 Hemi. That would be a nice match. 425 hp and 420 tq right out of the box.
