They are kinda naturals for coil on plug and EFI, if you are up for a technical learning curve. I am learning about EFI right now, and hopefully will be better able to speak on its merits or lack thereof in a couple months of testing. As a DIY, the learning curve is pretty steep. Having someone as a reference to lead you through it makes it about 80% easier and faster. Foxtrot Juliet Bravo | |||

I am looking forward to seeing the result of Larry Woodfin's LS build. Any of you fellas ever check out the Engine Labs website? I subscribe to their free e-newsletters, and just today it noted that Nelson Racing Engines has built a twin-turbo 447 CID LS that puts out 1100 HP through mufflers, on pump gas. Not saying it would make a decent bracket engine. I have not yet read the article, I am guessing it is very pricey, and there is possibly not a single GM part in that build, but the HP number is still very impressive. Here is a link for anyone wanting to take a look: EngineLabs.com 1100 HP Pump Gas LS Dan "Jim" Moore Much too young to feel this damn old!! | |||

Larry when it's time to get a cam talk to Martin Smallwood or Steven Balusik for camshaft they are experts. Embrace Daytona box they are great. If you have any concerns about setting up and programming Dennis King provides excellent customer service. Once you get comfortable with laptop it's a breeze. I used arp main and bead bolts. I like iron blocks better but that's just my opinion. I used high volume oil pump with .002-.0025 oil clearance and 10-40 oil. I know people are running tighter clearance and thinner oil for more power but that's where I felt comfortable for longevity of engine. You will love your ls | |||

It would be interesting to hear more on this combo, Like what heads and Cam you are running. What compression. Did you use a custom piston or off the shelf. Meziere Tech. Make sure your water pump is on whenever you check your coolant level. | |||

I don't know about the no GM parts thing. Lil brothers VW running 1.8L 6 cylinder making 750 HP with turbo and totally stock bottom end. He has started hurting parts lately but has lots of runs on it for stock 6 cyl. with turbo,not to mention some low 5's. New motor is being built stronger and bigger plus bigger turbo with 1000 to 1100 hp goal. So 1100 hp out of 447 ci shouldn't be too hard. America home of free. Brought to you by 2nd amendment. | |||

Larry Woodfin here is what my friends car did today won first race in sniper series this is engine I built This is what my car did in the 330 today, it is ridiculous, the first few hit moved around on brand new tires then it just literally locked down and didn't move, thanks to wholesale transmission, Davis racing engines, rupurt alky carbs. For a leaf spring setup going 6.60s off the foot I am happy. Also 6.0ls standard bore engine 4 years in car never had valve covers off, change oil and filter only. | |||

So how are the stock LS engines handling leaving on the trans brake? Will they hold up in a mild light car/dragster? Foxtrot Juliet Bravo | |||

It appears this is an older thread that's recently been bumped to the top, but I'll throw in my two cents: I've bracket raced my stock bottom end 5.3 since 2013. In my S-10 that weighs 2960lbs with me in it, it's been a best of 6.86 @ 98mph with a mild camshaft, a single plane intake and a carburetor. Since I have two cars, I rotate back and forth between it and my Cutlass, so it's kept the passes down a little bit over the years. With that said, this 5.3 probably still has almost 1000 passes on it. Other than general maintenance (oil changes and spark plugs), I haven't really done anything to it. I did recently change valve springs, but the springs that were on the truck before had lost ZERO valve spring pressure. This is where using quality valvetrain parts (Brian Tooley Racing) really pays off. I plan to build a 13:1 compression 6.0 this winter that should get the truck in the 6.20-6.30ish range if all goes well, and it's going to be way less cost than it would be if I tried to do the same with a standard SBC. If any of you guys have anymore questions, feel free to call Brian Tooley Racing (my workplace) and the sales/tech guys would be glad to help you out. Slow S-10 Slower Cutlass | |||

Jason do you leave on the trans brake? Foxtrot Juliet Bravo | |||

Oh, and out of stupidity.....is the bell housing the same as gen 1 blocks? Will a glide bolt right up? Foxtrot Juliet Bravo | |||

Yes a Chevy Trans will bolt up, The same except for 1 bolt hole. However the tricky part is the snout on the converter may need to be lengthened about .250-.300" to register in the back of the crank. Most converter shop will know this. They do make a bushing to do this using the standard converter but I found that it didn't work in my application. I'm using a Meziere FPS174 flexplate and adaptor plate everything bolts right in using a standard Chevy converter dems. Meziere Tech. Make sure your water pump is on whenever you check your coolant level. | |||

I realized I never gave a update on this motor. It was dynoed and installed in the Nova but the Nova has yet to make it to the track. The motor made 570HP at 6800 but didn't nose over until around 7200. Been so long I don't remember the TQ number. Meziere Tech.

Does anyone know anything or have any experience with the Chevy LSXR 454? Supposed to put out 775 Hp or more. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge. Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion | |||
