I have a 85 Oldsmobile cutlass with a stock 5.3, 350 transmission 3500 converter and 4.10 gear, my 60 foot 1.62 330 5.06 594 7.42 1/8th et is a 7.96 @ 84 mph. Could anybody have any idea to why my top end falls off so bad ? Could it be lack of fuel ?

Its a stock 5.3? Power peaks at just 5300 in a stock LM7 and starts to fall off. You haven't really said what "top end" is.

What is the fuel system on your setup?

JoeNova

Yeah there's a lot of questions that could be asked here. You didn't give us any real information.

Data logs could help with the supply of information.
As Joe said, need more info.
