Thanks GM.

mfw Gen IV LS engine in heavyfuck vehicle just waiting for some love paired with anemic transmission.

So what do I do, build a 4L80E and perform the fuckery needed to have it work with the current ECM.

Risk one of the janky 6L80E kits for a notoriously hard to tune, still weaksauce transmission

Rip all the wiring out of a modern vehicle, bolt a TH400 to my block and carb the cocksucker.

less power than the ford raptor

Transmission torque ratings are dependent on the weight of the vehicle they're in and the amount of grip it has. Stick that transmission in a Daihatsu Charade and it'll hold a million billion horsepowers.

The solution is simple: make your truck lighter.

looks like the engine and transmission match well together. whats the problem again?

460>439

Which one? Old Raptor, new Raptor, or both?

Want to moar power.
Cannot moar power, tranny is maxed.
Can't even bolt ons without exceeding what the tranny can handle.

In stock trim its fine.. in stock trim, but if I wanted to even approach 500bhp it looks like my transmissions gonna kerplotz.

The GM is a 2011.

It's a crew cab with a longer wheelbase than the Raptor.

Also,
2011 Ford Raptor Crewcab specs
379 cu in, 6210 cc
Power: 411 hp @ 5500 rpm
Torque: 434 lb-ft @ 4500 rpm

Also the GM isn't a Ford Motor Company built abortion so theres that.

...

The 2017 Raptor has 510 lb ft of torque, LOL
