I've heard about the *-10'* and Blazers getting better gas mileage when a V-8 is dropped in. Is this because the V-6 isn't "economical" enough for the weight its trying to carry?

i never did like the blazers except for the k5 my dad had but they loove gas, now a c10 would be nice except all the ones i see here or near me were in a mud hole or just rusted out completly or all custom i like mine semi stock for myself to build. ive had issues with that once

the 4.3 is not an efficient engine. if you put a 5.3 in any truck they get better mileage and a ton more power.

i like third gen f-bodies, light, tons of parts available for cheap. easy to mod, etc...

Thanks for the motivation to upgrade my engine Justin. And the good thing is, my PCM can be setup for either V-6'* or most of the bigger V-8'* with just a couple mouse clicks.

What is a good exhaust I could put on the car, something with more performance than sound, Ive been leaning toward magnaflow'* but ive never had them before so I wanna get a second opinion before I go get one and be disapointed

It'* next to impossible for anyone to offer any type of exhaust upgrades because everyone has different types of hearing/likes/dislikes. What sounds good to one person, may not sound good to another.
You might be able to do a 3.3 liter exhaust upgrade search on Youtube and compare side by side what every ones exhaust sounds like. But don't let the audio fool you. Cameras and PC speakers don't re-create the full audio spectrum very well.

yep everyone like something different. im not a big fan of the 60deg engine with a loud exhaust. imo the best ive heard it is when my firebird had the 2.8, i put a stock 350 exhaust which was just a single 2.5 cat back to a single in dual out 2.5"

mike sounds like it was an easy push

do they make headers for the 3.3? or would another set work i need to redo my pipes here soon

how did i miss this? anyway welcome!! nice car
