For an intake, we used a FAST high HP runner intake manifold part number 146104B. The high HP version of the FAST intake manifold has a bigger plenum volume and larger diameter runners. The FAST intake manifold is made of an advanced polymer material that doesn’t conduct heat very well. This helps keep the intake charge cool as well as being lighter than cast aluminum. The manifold also has integrated nitrous bungs and molded-in bolt locations and vacuum ports to work with all of the factory accessories. Best of all, the FAST intake manifold is 50 state legal with a CARB EO number. Another cool feature is that the FAST manifold is a modular design with intake runners that are removable. There are 3 optional length and diameter runners available so you can tune the manifold for your engine’s desired powerband. The removable runners can be easily ported and customized if you desire as well.
We will be running Radium high volume fuel rails part number 20-0232. Our NA engine will be running E85 which greatly increases fuel demand, these will help reduce the chance of any fuel starvation caused by fuel system resonance.
With better flowing heads and a bigger cam, we think this motor will make a lot better power than the one we built for Falken a few months ago. Stay tuned, we will be assembling the motor next and we will be running it on the dyno.

What did you rev this engine to produce 650whp?
7200 rpm
What’s the part number for the block you used? TIA
12673475
Hello Mike
Would you able to build for me Good LSX engine for Drift?
Of course.
Of course, we can, it just takes money.
Mike, great information! I was wondering to build this engine as you did on your channel but running off regular premium gas, what modifications would I need to make? How much power loss could I expect as a result? I’m eager to get similar horsepower at the rear wheels. But I’m sure the current setup wouldn’t allow for premium gas.
You would need a lower compression ratio. You would probably lose 40 hp or so.
How much did this build cost you total ?
Price out all the parts including the block and every peice needed to have a plug and play motor. Multiply that number by 2.5 and it will be close.to actual cost.
Actually, it’s a lot less than that. The parts are expensive. Labor and machining are about $4000, WPC of most parts is about $2700

Mike has $4000 plus $2700 parts = $6700
Pete’s rule of thumb parts [$2700] x 2.5 = $6750
Not too far off .
then there’s all the other stuff needed to have a runnin motor….Like Fuel ,Ign systems , ETC
There is no way the parts on this motor are only $2700! That is just the cost to WPC treat them.
What is the part number for the cam?
We don’t know, it was customer supplied and we didn’t recommend using it for drifting, not enough low end.
Will a 6.0l ls be able to use the same parts? I have a Pontiac G8 that I want to try and mimic this on.
Yes, but you won’t have quite the same displacement.
Thank you for the thorough explanation of everything. I wish more builders could/would break it all down as you have done!
hi mike, love your videos and information. can you please tell me the make and part # of the wrist pins you used in this build. thank you for your time.
Mike was $6700.00 around the actual price for plug and play
Mike said the labor, machining and WPC of most parts was $6700. That doesn’t include the cost of any of the parts. I would bet another $15000 in parts, my guess is $22000 to make it plug and play.
what about the core shift in the factory ls3 block?
what about it?
We notice some blocks are very thin on one side due to this. Some blocks are OK. Its just a cuation for people buying new blocks to do builds like this.
hello mike i am from holland and i want to build this engine for my volvo amazon 1966 project car
can i run this engine with 98 octane pump gas without race gas
or do i need to use another compresion ratio for that
i am planing to use it for street and strip use
hope you can help me
Yes you need to reduce the compression to around 11.5:1
Hi Mike. Love the content just one simple Question, Did you have the 6.2 Ls Bored over to a 6.8 liter for The Stroker kit or the stroker kit gave it the displacement to a 414 cubic inch?
It’s done with stroke, aluminum LS blocks can’t be bored out much, we said exactly what we are doing in the third paragraph, don’t be lazy, read!
Hi Mike. What oil weight do you recommend for drift ls3 with tight bearing clearances. Is 15w50 will be good choice or its too heavy ?
Thank you
Sure it is what we run.
Have you all ever experienced issues with the piston oil squirter mod to the main journals, and is there any reason to stay away from it?
