5.3 vs Hemi thread in the racing forum
#61
If you think that's heavy look at a new Ford lol. What do the new GM trucks weigh compared to the old ones?
What's the deal with the displacement comparison? GM could have put an LS1 in their 1500 RCSB 2x4 if they wanted (it'd be a big seller if they did) but they don't... Ford biggest engine is the 5.4L in their RCSB 2x4 so that's what everyone compares to. To me apples to apples is the 5.3L/5.4L/5.7L comparison

Sorry, I dont believe the Simular trucks, one Hemi one 5.3 that the Hemi would win.
My ext cab 5.3 with only free mods, flow pro muffler and K&N drop in ran 14.7@92.?. I have yet to see an ext cab Hemi get closer than .5 to that. Even the reg cabs with 20's dont hit those numbers.

Has a company come out with cams or stall comverters yet for the Hemi? Thats when the numbers will get really good I bet. They seem to be more mid and top end engines like the LSx's.
