Ok so my 1986 gmc c10 short bed ran a 15.1 with a stock 454 big block its got headers wieand intake and edelbrock carb i want in the mid 14s with out dumping alot cash i live in higher altitude and its got 2:73 gears posi axle what yall think i could do thats easy?

[zieg85]

3.08 or 3.42 gears

[fxrsrider]

you will get gains both by taking the choke out of the carb and with ram air.

[Kren420]

I definitely second swapping out the gears.

[FlatBlack77]

rear gears.

what kinda tires you running?

[454c10]

I got 373s from my uncle and i ran slicks for tires

Definitely go with a gear swap.Assuming you have a TH400 behind that BB 3,73 might be
a little steep for highway use,depending on what tire you are using.3.08 with a 28 inch
tire had me around 2600 at 70.If you are running a tall tire like 31.50's,you could go to
a wider lower profile tire simulating a gear change.Next I would do a cam swap,biggest
bang for the buck in my opinion

Will do thanks for your time
