Default Improving top end power.

So ive got the low end torque like a bat outta hell,when i pop the gas pedal your head turns into a bobble head,but once it hits 4,500+ rpm it just sucks. Heres what ive done some far.


Accel wires
msd coil
timing 6 degree's advanced
ngk v power plugs
ultimate tbi mods done
quarter mod,Now running at 14 psi fuel. Cool.
glasspack exhaust. No cat
K&n classic style round filter w/ that purty chrome housing.


Ive lightened the heck out of the blazer. No more 4x4(didnt work,didnt care to have it). No more front diff,cv axles,front driveshaft, 4x4 shifter. I still have the tcase.
Rear seat removed as well as carpet etc from rear seat back. Spare tire gone.
Going to build a flatbed inside since i use it for work etc. Hence why i removed the rear seat.
Has 3.42 gears with 30.9.50,15 in the rear. 235's in the front. Gonna go to 225,60,15's soon on all 4. Only have this weird combination since tires arefree.



Like i said,it has TONS of low end torque power,but once it hits Overdrive and at 60 mph it feels so gutless when you floor it. Yea maybe my expectations are a little high since its just a 4.3. I dont wanna put in a cam,or intake manifold etc. Id rather shell the beans for a v8 since you can get one for 200 bucks at a local pick n pull. But for now i figured id play around a little.


Im almost thinking about getting some 4.10 gears,but its just gonna spice up the low end,and still be lacking on top. So its not gonna help me much lol

The only thing coming to mind right now for the biggest top end is a turbo.

Turbo along with the required marine TB will give you more top end.
