416 Reliability?

You can get an NA 416 ci to the same level of performance as the FI bolt on if you add some goodies to reconsructing the long block...ie, nasty cam, heads, headers. The engine will be stronger too. Just be sure about your end goal. You don't want to build an 11 to 1 compression shortblock then later decide that you want a supercharger too.

Exactly!
The 11:1 vs 9:1 is where I am a little hung up. One builder did suggest 10.3:1 as a good middle ground. Would limit the max boost later to 8-10lbs, and still give really good NA numbers.
10-12 pounds on a built 416 is 700hp+ for sure.

what all goes into stroking the LS3? does the engine have to come out of the car?

I just have to decide forced induction or NA, for the long term.

You can't go wrong with an HKE built engine. Erik knows his stuff and builds great engines.

I'm going 9.5 to 1 with a Jannetty blower cam, other options would be a livernois 2c cam or the ZR1 cam. Either way, with a 416 ci, SC, blower cam and adequate fuel system you will make plenty of power. I'm actually trying to keep it under 700hp at the crank. The higher you go the more stuff you have to change, already doing a total suspension but if you go higher...rear end, axles, clutch,...

the other poster asked about what stroking involves...it is taking the bottom core block and replacing the internals with forged components and changing the stroke to add more cubic inches.

Agree, I was involved in my buddys 416 build with Eric and that thing is a beast and a excellent daily driver, He's raced at least 6 forced induction cars and has had no losses. He most definitely will be doing my build soon.

Anyone have a link or some info for HKE? Just curious. I wouldn't mind getting some info incase I decide I want to go this route one day.

I had my engine stroked by Eric at HKE and i am 1000% satisfied!

The biggest mistake I see alot is running the compression too low. With the old school motors you had to run low compression to fight detination. These LS motors are much more efficient.

For a turbo build you would want a 9-1 compression.
For a roots you want around 10-1
For a centrifical you want 10-1 to 10.8-1 compression

These compression samples are just that. The Cam choice makes a big difference on the static compression choice.

Blowers pretty much raise the compression. When the static compression is higher it takes less blower too fill the combustion chambers. Meaning you don't have to spin the blowers so hard to make the power.

I would definitely go HKE on the engine build. He knows his stuff. There are only 3 engine builders in the country I would trust and he's one of them.

We use a Callies C-series crank and Eagle rods, Wiseco pistons and GFX rings, ARP mainstuds, ACL coated race bearings.

honed, line honed, decked, balanced.. ready to go !

We can upgrade the rods and crank to Compstar for a bit more money. The C series crank is a favorite of Erik's to help save some money. The Compstar is the next level up and then the Dragonslayer. We use this combo in a lot of engines to keep costs down."

You will never get 900 + hp out of the Edelbrock. I am already on the smallest pully available, already stroked and even using E85...just sayin!

You have to have your engine machined/ honed anyway to match to pistons. You might as well do it to 4080 and go for the 418. The 416 is probably only a quick shop hone to 4070 and wont be machined to match steel rings imo.

Personal opinion, for the small cost to upgrade to Callies series I would go for it. Wiseco pistons are nice but I went with CP . ARP2000 bolt upgrade is a good idea as well. ls9 head gasket upgrade suggested. Install LPE or ADM dual fuel pump. Upgrade timing chain and tensioner, Blower Cam and springs with pushrods. This is going to be closer to 10K than 4K imo. Callies rotating assembly, pistons and rings, bearings etc is around 2500 just in parts. Cam kit 1500. Fuel pump 1000. Bolts, gaskets and labor 4K +

Sounds like you got a good build going on though..I like your style.

Good luck man!

Very good advice and right on target. I am at 10.02 to 1 compression. Dont rush and just take whatever pistons are available. Get exactly what you want to build. 4080 with a -13.8 dish for mine!

I love how so many folks are finally catching on to a proper ls3 blown build. Wish it was like this when I started....I would have saved so much money and time trying to learn.

We are the preferred distributor for Erik/ HKE
If a person needs an engine please come see me as we are the sponsor of this board and pay the bills
To be honest Erik would appreciate it as well, it frees him up to build the engines and take care of that end of things. If he is on the phone he cant get production done. I'll be honest; he and I are on the phone together when most people are sleeping probably 6 days a week. anyone in Texas I can save you the 8.4% sales tax as well

Yes Eric does work some crazy hours! I went personally to pick up my engine around 11 pm and he said he was working through the night. I shoped around for LS engine builders and HKE keep coming up. Nobody had any bad things to say, nothing but great things were said about HKE. This guy blew my mind away with his knowlege on LS engines.

I forgot about the tax break. How much is the shipping though?
