COME Racing 420ci LS Engine
A 420ci LS Chev V8 engine built from a new 6.0L L76 donor engine. We took a new 6.0L factory alloy block. Bored it +.030" and fitted one of our 4.100" stroke 4340 steel LS cranks, our 6.1" "H" beam 4340 steel rods, Diamond Racing custom high compression forged pistons, Total Seal rings, King rod and main bearings, new GM stock volume oil pump, Dana single row late model timing set, factory VE-VF Commodore oil pan, Powerbond steel harmonic balancer (not underdriven), COME LSCH-923 camshaft 236/245 degrees duration @.050" ground on 114 degree lobe centres, .617" lift on both with production 1.7:1 rocker arms, PAC conical springs, stock unported L76 square port heads with a competition valve seat job, stock L76 intake manifold fly by wire throttle body fuel rails and fuel injectors,
factory coils, dyno tested with Pacemaker of the shelf 1 7/8" primary 4-1 headers. Tuned using HP Tuners software.
In room power 606 bhp @ 5750 rpm and 596 ft.lbs torque @ 4750 rpm. This is a pretty simple to emulate combination which would make an incredible heavy street car performer.
For those who like to see corrected power for a perfect weather day this was 617 bhp @ 5750 rpm and 606 ft.lbs torque @ 4750 All testing was done on our Superflow 901 dyno at an acceleration rate of 600 rpm per second.

Our Project Holden V8 has been completed. We missed out on publishing the teardown of the donor engine, machinework and final assembly. This has been filmed and will be uploaded eventually. We decided this engine combination was just too good not to upload the Dyno test running so any of you Holden V8 fans can easily emulate this great street engine. In fact this is a great daily driver with gr...
COME Racing Holden V8 oiling system mods
Переглядів 39 тис.9 років тому
There are so many complaints about the Holden V8 oiling system, that it's actually quite annoying till one puts things in perspective. Do you realise the Holden V8 was designed in Detroit Michigan for General Motors Holden in 1965? Given the engine began life in production Holden vehicles in 1969 we need to step back and give our Australian built "plastic" V8 a little breathing room. Considerin...

Project Engine receives a new cam
Переглядів 44 тис.10 років тому
After grinding several cams which may be used in our Project Holden EFI V8 engine we pulled the stock cam out. After cleaning old gaskets and preparing the new cam, we installed the new cam, and new timing set. New lifters were fitted along with some LT-1 valve springs to increase spring pressures to handle the extra valve lift, duration and aggressiveness of the lobe design. Lifter pre-load wa...
Project Holden V8 Engine comes off the Dyno
Переглядів 13 тис.10 років тому
As the initial dyno tests are concluded our Project Holden V8 comes off the dyno. The stock 5 litre EFI engine is found to be in great mechanical shape making 296 BHP when tested with Pacemaker 1 3/4" primary header size Pacemaker Tri-Y extractors. With the 1 5/8" Pacemaker Tri-Y pipes peak power is a little lower at 282 BHP. The torque curve for both pipes is very similar in shape with a peak ...

Our donor engine (Holden 5litre EFI V8) is given a wash and an oil change prior to mounting it on the engine dyno. After installing the engine on the dyno a fresh load of mineral based "Martini" 20w-50w oil is added with a new GM filter. New NGK spark plugs are fitted after a compression test on all cylinders is performed. Ideally the engine should be warm to test compressions but our main goal...
COME Racing Holden V8 buildup project
Переглядів 6 тис.10 років тому
Take a Holden EFI V8 cutout engine out of a VN-VS Commodore. Run it as is on the engine dyno to baseline it and begin to make changes to evaluate the costs versus the performance gains. We find many enthusiasts make changes that are not always cost effective. The biggest mistake is often over camming these engines with a resultant dramatic loss in acceleration of the car.

Excellent information, where are you now
what size is the restrictor hole
How did you get the cam out so easy haha
COME engines are a top engine building team. My opinion i have cut the back part from the rear main journal off an old worn scrap crank that i use to set the rear rope main seal in place.
Why wouldn't you change the valve seals while you had the springs out?
I don't know why, but old mate talking about the typical lifter tick on startup made me chuckle a bit. Love my 5Ls. Even with all their faults
Are you guys still in business? Thanks!
Handy tool for the shed
Nice 🇦🇺
Can you make titanium or Inconel cams and can they be hollowed out?
I didn't end up using the hvh-234 cam I bought off you. sold it. But mark my words, "that is a Far better grind cam than the crane 286 everyone on Facebook thinks is the go.
Great detail in the video thanks
Hit the water jacket on mine on one cylinder, welded it myself, it never cracked or ever leaked. Crankshaft I used was a highly modified fully counter weighted, offset ground FORD Y-block steel crankshaft, 7/16" H-Beam Rods and ground the block to achieve .060" clearance to the Rod Bolts.
Standard rope or "low drag "??
That thing sounds nasty! 👌🏼
Makes me wonder if you hone the lifter bores…?
Niiiiic I assume we are already running high volume oil pump…..?
Leaky rear main seal is factory spec on these
Plate cam grinding machine video send me
I faithfully built this engine a few years ago an it’s changed my life. I stuck to the exact brief with a 2200 stall and 3.45 gear. Great daily driver that does low 12s at the local unprepped track. Since then I’ve tried a 2500 stall, then a 3000 9 inch stall. I love the 3000 stall and it really unlocks this engine down low. I blew my Th350 a few weeks ago and I’ve just tried a powerglide and 3.72 gearing. What a great combo with a 4K converter! I’ve got a bit of nitrous and racing in a few weeks. I’m also building a 355 with COME gear. That’s a power adder forged engine. But this 383 is the envy. It just works!
This is greatly helpful. I have to do the rear main rope seal on an aluminium Rover/Buick 215 ci/3500cc V8 and the Rover people on Facebook pointed me in your direction. I'll have this video on a loop in the shop. My issue is that the crank will be in the engine, kind of. I have the engine upside down on a stand, the rods still bolted to the crank, and a chain block strapped to the crank holding it up out of the main saddles.
I just found your video, loving it
10:00 That's very informative thanks! I'm restoring an Opel Rekord P1 1959 1700cc engine and this video helped a lot with understanding these kind of seals. It seemed so hard to install at first because the Opel workshop manual mentions all kinds of special tools needed for installation, but after watching this video I feel more secure with installing the seal! Cheers!
can you do a tutorial on basics of camshaft grinding and how to setup and operate?
Great video guys with heaps of excellent info. I am going to be rebuilding my vs clubsport 304 this year sometime. I freshend up the top end last year, vn - vs ported heads. Next a full tear down and off to the shop for the treatment you have shown in this vid. Great vid guys. 🇦🇺
👍👍
Is it true it has to be clocked quarter inch so it wont leak ?
Edge orifice solid lifters and the cam bearings installed correctly works pretty good too, oil flows to the path of least resistance so if your clearances are loose then that's were the oils leaking ,good info for higher end engines but obviously these mods should be left to experienced engine guys, good post
GREAT MACHINIST !
COME RACING THOSE GUYS ARE GREAT NOW THATS A ENGINE BUILDER!
Thanks very much for the good videos. My question is my 308 is stripped down for a rebuild. My motor will only be used on the street for mostly normal driving. Is this modification really necessary for my application. I would really like decent oil pressure when hot at idle as this will ensure the motor last. In the past I have relied on thicker oils to help bump up the pressure. I would appreciate your input. Thanks
I was 16 years old had just driven my ht home when I first watched this and I still watch today..
Yes what happened to the cam dyno run. I assumed the engine crapped out as the next dyno run it has a sump and alloy head fitting.
Can l come and pick your brains on Holden's because you know what you have talking about Holden's
Hi where did u get your camshaft moly lube? Ive looked everywhere?
you can do this to crank too
Don't need that bullshit, love it!
What a pain in the arse
I reckon you could pull 400hp from the 304ci...I think 480hp from a 383ci is embarrassing really.Thats a big engine capacity.Seen 400hp in 4 cylinder vehicle's.i mean there's 600hp 355's getting around,so this 383ci seems a little redundant really
Excellent vid. I’m just about to start an LS1 build. Always great to see what the machine shop is about to do to my short block.
Thank you for your time, much appreciated.
Thank you so much for this amazing series of videos, finally here is some very informative and professionally done videos on an iconic Australian V8 engine. Sir I hope that you continue to make more amazing videos. All the best.Regards.
Your floor are so very clean, how could that happen
Best
excellent explain so nice
Deadly mate I'm sending my 308 to them
Terrific video thank you for posting!
hi can you please tell me is the vt -vy v6 cam lobes r 1st lobe intake followed by 2 exh lobes then another intake lobe. ive been measuring a new cam & im getting mixed figures.
It ain't a Holden if the rear main isn't leaking.
Why is it you check deck height without rod bearings? Thanks for taking the time to do this video.
