LS1 408ci engine

[36vette1]

pmsl ... a true ignorant comment ! name a jap v8 that can reliably make 1000bhp with a £10k budget ?? . let me guess your either a supra or skyline owner .. the amount of idiots who seem to think there`s makes around this figure with a few k spent is truly comical !

[InShatteredMolds]

589 hp, holy poop

[rodneys0909]

mustangmike from the "fix or repair daily" camp...lol- top fuel dragsters use push rod engines- ask Sainty engineering- they cant make 4 valve engines last on Nitro- they only use 3 valve heads and still cant beat the pushrod Hemi's. Ford is the absolute pits car maker ever- always behind the world in every tech advance, so STOP talking up your 4.6... LMAO- you yanks are a weird lot- MPH speedos , but you measure displacemnet in CC's these days- Guess 5.0 sounds "wicked " to rapper kiddies?

My 408is a 1970 400small block 40 over and with the dart heads its right at 520hp at flywheel not bad for only 2000$ the car only weighs 2600lbs 488 gears its real nice and quick

[SHTFzombies]

i want to put a ls 1 in my chevy cobalt :D

[mustangmikeca]

pushrod piece of shit

[MrRandy1971]

you are ignorant

[1986z28owner]

Go suck another mustang owners dick, and think your POS 4.6 is fast.

[AKxALLxDAYx]

I love the 408 its a good engine.

[PhiLambByDamnn]

I read in your comments that you wouldnt recommend boring out the ls1 but thats what your engine set up says as the vid starts...are you having probs with the ls1 or what? reason im askin is that im back in forth on the ls1 and ls2 block to build my 408

thanks, ryan

Don't even bother building a 408 with an LS1 block, unless you have access to free machine work, and 4.030" sleeves on hand. Thats what you would have to do, remove the stock 3.9ish" sleeves, and press in new 4.030" ones. But then the best way to fit a 4" crank in the Gen III/IV block is to use longer than stock sleeves. It keeps the bottom of the piston skirt from coming out of the bottom of the cylinder, @times a problematic issue. In which case, go ahead and use an ls1 block.

[madtownmadman]

The LS7 is the only LS-based motor to use longer sleeves in its bores, as it is the only one to have a need for them, with its 4" stroke. Everything else is a 3.62" stroke, and shorter sleeves, (or cylinder bores in iron blocks) are used. You can run a 4" crank in a short sleeve block, but you may or may not run into the issues I mentioned earlier.

[titoramair01]

well this is my build ideas stock ls1 block forged internals for nos, nice cam,afr mong. heads, headers intake my opinion

[kdog122]

HAHA HA HA did you hear the trans break go off lol

[italianmobsta74]

theres no trans brake...

[thacrunkmasta69]

Its sad how little people know about cars an yet still try and talk about them.......

[andyg256]

hmmm i think my vy2 clubby might be due for a bit of an upgrade

[rodders188]

Im in New Zealand having all sorts of dramas with my LS1, if i wanted to do a drop in engine and was looking at spending 16000 Aus what could i get done, the engine now is a 300 KW CB4 Engine,

[comeracing]

The LS engine is frankly hard to beat from a production engine potential.

We just built 3 440ci versions, pump fuel, with 600ft.lbs torque and 610 bhp @ 6000 rpm and they are very tractable. All with production GM heads and intake manifolds.

Hey bro I may be buying a 99vette with a LQ9 in her supposedly the car was built for up to 1500bhp. The guy had a D1SC on her putting out 735. Now it is a N/A engine. Do you think with a piston swap I would have a beast at 11:1 compression vs the 9"5 it is putting out now? Or should I enjoy the streetability and go with a 200 shot N20??

[eikichi2009]

Just about any Japanese v8 of similar displacement is superior to the LS1 in terms of both power potential and technology.

I am a Ford guy but I must admit I am a fan of the LS series of motors. Light weight, compact and big cubic inch potential. Us Ford guys need a motor like that for F150s and performance applications. Cobra motors can be built to run hard but I just like naturally aspirated big inch motors. I believe the LS series is a terrific engine for swaps.

My toy: 66 mustang and a 372 cleveland (stroker)- 518hp @ 6400 rpm - cheers.

[JLards]

sponser me ill drive it around all day,and throw people left right and centre at come racing

[a43468camaro]

so its really a ls2

[a43468camaro]

how did u get a 408 out of a ls1

[comeracing]

Using 6 litre (4" bore block) with 4" stroker crank and all the LS1 top end parts. The 6litre block is a direct swap for 5.7 LS1 block aside from minor differences to timing case cover and valley plate.

[marshn8r]

hey, i hear you can still use the ls1 block but a larger head gasket on it to take from 3.905" to 4.000" bore as required. i am looking at buying a stroker kit for my ls1 that i have pulled apart in my shed. maybe you could point me in the right direction. 383 and 408 strokers are 3,300 au correct??

[comeracing]

Would not recommend boring LS1 block to 4.00" Not enough meat there in the sleeves. Pointless sleeving these blocks when you can buy a 6 litre 4.00" bore block. If you must stay with 3.9" 5.7 block go to a 383 stroker kit. Or, replace block 6 litre block and use LS1 top end to make 408. Very effective combination. Yes all stroker kits are $3300.00 but we also have several versions. Email me directly from our website.

[ezcondition]

the iron truck block right?

[wadelavender]

i want that in my vy monaro right now !!!

[madtownmadman]

Damn, 571 lb. ft.!

[bucko1671]

Men, you do excellent work. If possible can you post a video of one of your engine dyno runs with your new release 439 CID LS7 block L92 heads L76 intake combinations.

[35057]

What facility is that? Or did I miss it? Good work! I'd love to get paid to do that stuff!

[AutoPainter7]

Those headers have to go lol ... ceramic would do it more justice appearance wise ... but i guess its not the looks that really matter ;) ... nice motor from what i see ... i have a ls2 l92 408 in an 05 silverado ext. cab .... always good to see more people building them

[comeracing]

You are right about ceramic coatings. Been too busy to send those pipes away to HPC. Will actually do it soon while we have a break in the LS1 engines going on the dyno.

Sam

[saxuak]

awesome. admire your work and keep it up.

[saxuak]

put more videos like this of different engines pls.

[comeracing]

Will be posting as many as we can.
