People who have made a 408... I need a total cost!! I am planning to stroke my 6.0 to a 408 this winter. I need to know real world numbers of what it is going to take. This is how I have it figured so far. I am looking to see if there are parts I am over looking or things I am missing that need to be done.
$2000 for rotating assembly from TS (a few add ons to support nitrous)
Around $500 for machining(boring and other odds and ends)
$300 for bearings
$300 or less for gaskets
This make the build right around $3000. I already have a custom tune with free re-tunes from blackbear. I will probably need valve springs and need to pick out a cam but I think that pretty well covers it?! I plan to stick with a stock intake for now and port the heads wile they are off. I will get the fast intake some time in the near future after the build but that will have to wait.
How much did you spend building yours? That is the question. Please answer only if you have built one and have a price you spent. I really need to know what kind of money I need to get togather so I can get a saving plan in order. Thanks

I would wait and do the fast intake and cam when I did the motor... the intake is going to hurt your numbers and if you are going to be getting one why not do it right and all at the same time?

I think you can get a 408 from TSP for just a few hundred more than that if you thinking about building this yourself.

Our 408's are $4274 (Eagle,Scat), $4474(Callies) and $4600 ( Callies nitrous 300 hit or higher) in short block form.

I had $8000 tide up in mine when I picked it up from the build shop. I had $11000 in it by the time I put it in the car (myself). Now I have another $5000 in it due to the DIY GT-88 turbo, DIY dual fuel pump, and upgraded fuel system. I am close to starting it back up. My point is it takes more then most poeple think. Of course I started with all new parts, my original engine is on the engine stand and the other parts are all up stairs in the attick. Not to mention I started this project 5 years ago and the cost of the LS has dropped alot as compared to then.
All said I think you will have an easy $6000 in it before you start it up.

I know it will hurt my numbers conpaired to the fast intake but another $1000 is allot to add to a tottal bill. Also changing the intake is rather easy therfore not a big deal to change later.

People are forgetting one HUGE part of suggesting a 408 cube or larger engine - Stock LS1 heads, even ported ones, are not going to flow well enough to support the size of the engine. You'll have an engine that peaks way too early and is down a lot on total power potential. Especially a 427, which would need a set of L92s at minimum to achieve decent airflow in the 5000 RPM+ range. Can you put a 427 shortblock under a stock set of heads? Of course, but it's going to be a torque monster with a really narrow powerband. Not much fun IMO.

I don't know if they are the same but I have 6.0 heads. I would love to put better heads but ultimate power will come with time such as the fast intake, then maybe some better heads. I plan to port the heads so that will help.

These are the prices straight off my invoice.
Ross Pistons $797.92
4340 Tool Steel Tappered Wrist Pins $196.40
Oil Ring Supports $59.60
Piston Rings $165
Eagle Rods $450
Rod Bearings $64
Main Bearings $145.69
Timing Set $156.98
Dampner $229
Oil Pump $204.95
Moroso Oil Pan and kit $679.95
L92 Heads $450
Cam $345.95
Intake Manifold GMPP EFI Single Plane $380
Pan Gasket $53.95
Rear Main Gasket Set $33.39
Valve Cover Gasket Set $25.95
Valve Springs $189.95
GM Perf Lifters $319.95
Valve Locks $35.95
Retainers $58.65
Head Gaskets $181.90
Vat Block $48
Bore Block and Hone with Torque Plate $140
3 Angle V8 Valve Job $175
Port Cyl. Heads $700
Deck Block $75
Balance Engine $225
Assemble Engine $980
ARP Head Bolts $159.95
ARP Main Studs $185.95
Cam Bearings $36.95
Intake Valves $111.60
Exhaust Valves $108
Pushrods $108.25
Valve Stem Seals $32
Total===$8365.78
Notice I did not mention the cost of the crank or the block. This was the cost at the builders shop, I already had the block and crank. I bought the block and crank back in 2004, I gave $300 for the block and somewere around a $1000 for the crank. I also had to get valve covers, valley cover, front cover, rear cover, and all those bolts so I bought a 4.8L with bent rods in it for $200 to get those parts. This stuff added $1500 to the deal. So now I am at $9868.78.
I also bought the rocker arms, Lifter guides, SFI Aprooved Flex plate, and the Edelbrock elbow. I think all that stuff was around $300.
So now it is up to $10168.78 for my 408. That was not including the water pump, alternator rebuild, starter rebuild, belts, hoses, and fluids.
Then came the aftermarket radiator, intercooler, GT-88 Turbo, dual fuel pumps, Turbo hot and cold piping, two hot wire kits, electric oil pump for turbo, all the SS braided hoses to oil the turbo and all the ANSI ends. Not to mention the $3500 waisted on beafing up the 4L60E trans for this build (I should have spent it on building a 4L80E) and the $900 convertor or the $3000 I have tied up in the Moser 9" rear end both of wich you will need to beef up if you build the 408.
Yes the 408 cost me more then $10,000 to build, I am not over stating this. I am sure you can shave $2000-$3000 off this price if you reuse as much as you can off of your present engine (covers, heads, block, intake) and if you do the assembley yourself. I will do the assembley myself next time. So that puts you down to say $7000 - $8000 just for the engine ready to drop in.
