Finally making some time for this in between working on the ongoing M715 build
Here’s the FJ40…
I’ve owned this since 2000 when it was a bone stock rusty basket case. It’s been through the standard evolution of changes.
In 2003, I installed the Vortec 5.7 from a 1996 Suburban and at that time, I think that swap had only been done a handful of times in an FJ40. Fast forward 21 years and the truck has driven all over the western US, back and forth to Alaska on the Alcan and has tackled some decent trails. The engine has always been SOLID but I’m looking for more horsepower than the maybe 250HP it’s cranking out
Bought a 2001 6.0 LQ4 in 2017 (yeah none of my projects happen fast ) now it’s time to install it
Engine was fully rebuilt although it only had 40k on it. Looked like the previous owner treated oil changes as highly optional and the motor was full of sludge. Did a mild Texas Speed camshaft and after a LOT of research, installed 862 heads from a 4.8 LS engine. Had the heads milled .035” also.
The 862 heads are already higher compression than the standard 317 heads on these engines. It “should” be about 11.5:1 compression and will need to run on 93 octane. Looking at dyno results from others, the engine should make all its torque and HP under 5,000rpm which should be ideal for wheeling. Guesstimates say the 6.0 should be right in the neighborhood of 430HP
Tore the truck down today…
