theres 3 of them around here..flatbeds

 

i waxed the floor with an 08 chipped duramax with my 5.4....

 

I smoked a 5.4 towing a fifth wheel with my 4.2.......

 

I smoked a Firebird...

From the 80's...

Which was beat to hell...

Probably had 100K miles...

Probably wasn't running on all 8 cylinders...

 

I beat a modded 99 gt..... but it was on my trailer behind me....

 

i wouldnt doubt it!!!

 

this dude i know saw this thread and swapped in a 4.2 in his f800 dump truck..i told him that was a GREAT idea!!!!!!!!!!!!!!!

 

the '99-'09 super duty trucks have that as a base engine

 

haha i really doubt that

 

I just owned a quad turbo v12 bugatti eb110 gt in a race with my 4.6! I imagine it would have been better with a 4.2 in there. Either way the bugatti owner was crying and he said he was going to buy the next 150 he could get his hands on as long as it wasnt a 5.4

 

there is a big difference between a 10 second duramax and a straight piped edge chipped duramax

 

 

dude you woulda butt raped it if you woulda had a 4.2!

i think i should let my grandad read up on this thread so maybe we can swap out the v10 in the farm truck for a 4.2!

im ready! itll haul the tractors and bulldozer the same as the 6.8 AND get better gas mileage!

 

I've seen the 5four smoke those built Duramaxes. Joey (built54) has a cool video of that somewhere. Made the guy eat his words, that's for sure. Awesome vid!

 

well if it was the early 80's like 82-84. it could have been brand spankin new and you would beat it. if it was a 350 and you beat it, then yes it was beat to hell. but it also could have been a V6. and they offered 2 different 305s and one of them only came with an auto and one of the rear end ratios they offered was horrible. made the car go from about 7 seconds to 60 to about 9-10 just from the different rear end ratio.

I used to beat GTs all the time....when i had my trans am lol. i tried in my 4.2 against a SVT cobra. kinda pulled up beside him both going about 40 and i took off since i knew i would need a head start. he blew by me but it took him longer to pass me than i thought it would take. my trans am would still have beat that thing.

yeah, like 150hp and 400Lb-ft of a difference. ive seen a video of a 12 second powerstroke beating a turbo honda civic and that would take a little work to do...on the powerstroke AND the civic
