Chevy Gen V LV1 (LV3) v6 at 7000 RPM on Westech Dyno

[@timorgano]

Sounds good. I love that as soon as the video started I recognised the legend himself operating the dyno

[@MrNeildrake]

350Hp at 6800 and 317 tq at 4900. Headers are 1-7/8 long tubes for 2014 silverado with 5.3 V8. I removed one primary.

[@Selmerpilot]

Made a good bit more with the Webers didn't it. Same exhaust manifold in this dyno run as the one with Webers?

[@MrNeildrake]

@@Selmerpilot it did, however the webers still made 337 hp with this combo. I ran the same long tube headers as well.

[@Selmerpilot]

@@MrNeildrake Good stuff I see! I am actually trying to make a Weber 48IDF manifold for this Maserati Merak engine I have, know anyone who might be able to knock one out similar to yours? or if you're interested please let me know. Best - J

[@MrNeildrake]

@@Selmerpilot a good start would be to buy the weber flanges (can be found on ebay) and see how close the ports on the head will line up. I chose the IDA mostly because the throats are spaced wider and lined up with the cylinder head better than IDF. My job was made a bit easier because the head flanges were off-the-shelf from ICT Billet (I used 8cyl ones and cut off one cyl). You would have to dimension/draw up those flanges to have machined or cut. Then it's just a painstaking time of connect the dots with the IDF and head flanges using tubing. For runners, I used 0.120" wall 5052 aluminum. It's easier to bend/beat than 6061 and still welds well.

Cam specs?

[@aaronmcconnell9369]

Awesome. Great to see development of this engine. Always loved the all aluminum Nascar v6 engines. LV3 might not be far off

His wife packed him a cookie for Dyno day. What a keeper

[@Sdpartscenter]

Hey now that sounds healthy!

[@MrNeildrake]

Thanks. The Texas Speed 660 spring kit you sold me was still keeping valvetrain in control at 7200. Help me find another short block and I'll make a 5.0l version.

[@Truck-vd8sh]

@MrNeildrake shop in Ft worth has a few.

5.0L v6?

[@dennisrobinson8008]

Sounds incredible

[@luckautofab4461]

What did you use for ignition control on this engine? I saw you modified an HEI on another engine

[@MrNeildrake]

I used a PE3 IG2 from Performance Electronics

[@boostedbird4799]

Who made the long tubes? Any power numbers available?

[@bryanhallman8183]

Hell, yes! How does the LV1 like forced induction?

[@MrNeildrake]

Check out Scoggin-Dickee Parts Center. Nick has helped me out and he has gotten 700+hp on his LV3 on boost. kzbin.info/www/bejne/oaCkp4iDadyJmbM&feature=share

[@bryanhallman8183]

@@MrNeildrake Yes, I saw that one. The LV1 lacks the variable valve timing and the MDS, so I was curious about that difference. I still love your 6-bbl intake that you made.

[@MrNeildrake]

I’ve built one of each LV1 and LV3. The rotating assemblies and heads are identical. The LV1 is a bit cheaper to hot rod because it has non-dod “LS7” lifters already. For boost and big power, the LV3 might be better because it has piston oil squirters where LV1 does not. Both are VVT but I eliminated that and just run an LS3 style single bolt cam sprocket.

[@bryanhallman8183]

@@MrNeildrake One more quick question. Would an LT-style bellhousing work with these engines? It could make finding adapters or transmissions that fit much easier. Thanks for the responses.

[@MrNeildrake]

Bell housing pattern is identical to LT and LS v8s. I have a T5 going behind this engine using standard sbc bell housing.

[@stevenrhoads8707]

What is the reasoning behind removing the vvti? I am preparing to build something very similar for an airboat

[@wed3k]

Piston to valve clearance

[@JTsMechanicShop5748]

One question why did the oil pressure went from 92 pounds to 70 when the engine was sill climbing up in the rpms

[@MrNeildrake]

The Moroso oil pan that I used has no windage tray/scraper plus it’s only about 5-6 quart. Good eye, we’re probably getting oil aeration at high rpm.

[@MrNeildrake]

@@bishop94z I didn’t know that. Suppose I’ll keep my eye on it when finally running in car

[@MrNeildrake]

@@bishop94z no worries. Please link article, I’d like to check it out

[@ArmenianLegend]

Have you had a chance to weigh this engine? Would be great if you made a vid about it can't seem to find numbers anywhere

[@MrNeildrake]

The long block weighed 315 lbs.

[@SparkysAdventure]

What manifold?

[@MrNeildrake]

It’s an ebay single plane LS3 manifold with 2 runners cut off. It’s mounted on ICT Billtet LS3 to gen V intake adapters with 2 ports cut off

[@artjomslivenskis429]

Wow! Which intake manifold is that?

[@MrNeildrake]

Manifold was a single plane Holley ebay knockoff for LS3 v8 mounted on ICT billet gen v to ls3 adapter plates. I blocked off the rear ports

[@artjomslivenskis429]

@@MrNeildrakeWow) Your ingenuity fascinates.

[@rustystick]

@@MrNeildrake what ignition setup?

[@MrNeildrake]

@@rustystick it’s a PE3-IG2 from performance electronics. It’s run off just he crank sensor driving stock coils
