Important!: 4.8L Dyno Numbers

[Low01silveradO]

My 01 4.8 ECSB put down 333/309 on the dyno. I'm very happy with it.

The tuner stopped at 130mph and the graph was still climbing and would've made it to around 345ish hp but he didn't trust the stock driveshaft running that fast.

I'll get 4.30s and truetrac one day and put it back on the dyno for a full pull.

can you list the parts that you used to build the engine ?

^Read his sig. I'm curious as to how much of that was from intake swap alone

I used:

214/222 .595 .602 on a 113 + 2 EPS Cam
243 heads milled .040
NNBS Intake Manifold
Stock 78mm Throttle Body with FAST adapter
Longtubes/ORY
7.375 hardened pushrods
Ls7 lifters
Ls2 trays
Tr55 plugs
MSD Super Conductor wires
160 thermostat
And hoped for 330+


The tuner said that intake must do a lot because he was surprised by the numbers. And just as I've seen many many times, he said 90mm throttle body would make it much more difficult to drive. And it would lose low end considerably IMO from what I've seen. Need as much low end as u can get in a truck. I'm lovin it, and very happy.
