150 shot on a 4.3
#4
Only have one pic of the install, no videos yet. I have a spot locally that is marked out at a 1/4 mile, crossed the line about 91 92ish(bone stock trapped 78). My 5.3 is going in within the next couple weeks so I just wanted some fun out of the 6.

The 4.3s can handle some NX 
However the **** distributors can't. I wen't through 2 of them on my 4.3L within about 5 yrs.
The 5.3L is night and day difference and you will love being part of the V8 club!
Post some pics of the swap devin!

I will, my brothers got one more week of exams left then we're getting at it. I still have throw my heads and cam at the 5.3 then it's ready. Gonna throw the truck on the dyno this week just for ***** and giggles get some numbers with the 4.3 on the bottle. Be cool to see 300 but who knows.

Nice, what H/C setup are you running?! Pm me if you'd like to keep it DL
Make sure you have all your parts together before the swap. We did the swap in about 15 total hours. It can be done in a day for sure.




have you run it at the track?
