good kill, any track times? or any idea wat u should run?

Is that the TBI 454 engine from the early 90's? If so, those TBI 454's are known to be pigs/turds.

Good job though, a win is a win.

Congrates, but even though its a 454 doesn't mean much, this isn't the 70's anymore..LOL

For comparison my 440 ran a 15.7
now with the ls1 swap......14.0.....what the hell? LOL before and after weight was a 600lb difference...

your 3200 stall pretty much makes up for any low end tq the 4.8 doesn't have vs the 454...


is there any more to the story? any trash talk before, what did he say after?
Many people told me i was going to miss the low end of the 440...I don't..if anything the 4l60e with the low 1st gear feels tourqeir then my 440 with the 727.

Yeah I think it's a 93 454 ss original ..... Yeah there's a lot of **** talking still... That my truck was cammed... Supercharged ... That I was squeezing ... Etc... That truck smoked my homies truck 07 rcsb 4.8 intake... Superchiped.. On stock 17's.. By 3 car lengths... So I was like it will be a close race... I just did my Lt 's and exhaust... So maybe that help too... I still watiting on a retune...
Also isn't his truck way lighter than mines???

my guess is the other 4.8 driver couldnt drive. TBI engines are the biggest pieces of **** ever.

some tv show tested these once, 15.8 all stock. If he was stock then I would of guessed you could of took him ease but I thought I would of been closer myself. I know they dont hook up to well did he spin?

U can tell the converter from the launch, and yes it does wake up our low torque 4.8 however our trucks are heavy as **** so that was a good kill. One day I will be winning. Maybe when n if I ditchel the rims. Seriously thinking about selling or trading for a blower lol
