There's engine builders and then there's engine builders . I've never seen a crankshaft balanced like this pretty amazing , I just bought a beautiful 97 Chevy 3500 from South Carolina that needs an engine, but of course I need big block 454 or ls engine . I wish I could afford to have these guys build it for me ,but I don't even have a block yet. Keep up the great content I'm learning more everyday.
Taking weight out of the ancillary items makes complete sense. When he spoke about the crank flexing as the heavy sections came around was a "light bulb' moment for me.
Man, you do good work, I wish I was closer, I'd definitely be a customer. I went to school to be an automotive machinist in the mid 90's when I lived in Sacramento. I tried working at a couple shops. One had a robbery/ shooting across the parking lot, the owners wife and the other worker were doing meth. I got a job after that at Rex Hutchison Racing engines. I was going to have to wait for someone to die before I moved up from donkey boy there. I wound up working for a glass company. Good money, but not my passion. I should have found a way to start my own shop. I love this stuff. Hard to find an engine whisperer anymore. I'm a big fan for sure. Thanks for the videos. P.S. I live in Northern Minnesota now.
SERIOUS knowledge here, in the mid 70's I thought my 67 Camaro Yenko clone 427/425 was fast and powerful, I could ONLY imagine driving it with this engine
OK, I've been digging around, and reading and reading and researching, etc. I have found several posts of yours from the past, saying that cast cranks and external balanced assemblies are not a good idea at all. One post (or two) you said you used to find cracks in your cast cranks after only 200 passes on the engine. Also, reading other peoples posts, I get about a 50/50 view of GM factory cast cranks either being good or bad. Some people claim their crank broke after only a few passes, and they'd never use anything but forged again, while other people claim to be using cast cranks their entire lives in drag cars, and never had a problem with them (most seem to be claiming between 600-700hp). My block is in the machine shop right now, but my crank (GM factory cast) is finished (turned 10/10). I originally was going to use this crank for my build (basically the very same build you have going here), but the more I read around, the more I'm unsure of using the cast crank, yet now I see this video and see you using a cast crank and external balancing for this 620hp build. I'm totally confused!! Will it last or won't it? Will I be looking at replacing the damned thing only after 200 passes? I hate to spend $1000+ on a forged crank if it really isn't necessary, but I also don't want to put in all this money just to have my hard earned money shit down the toilet, because of something so simple as a crankshaft choice gone wrong. Help!?
Balance the counterweights themselves. If you balance the weights then the owner has to rebalance if he ever changes the harmonic balancer or flywheel assembly. Or if one of them cracks they have to replace and the new ones may not be same weight.
Right here is where i start to like 427s more than 454s , lol ,, if ya gotta use a stock crank , a 427BBC can be pretty scary for most street strip guys , a 366 BBC gets a factory steel crank that will make a 427
Thanks for the video, yet I don’t understand why to go through all that trouble to leave it at ~3g of imbalance on both sides and not zero? What was the point of not do a couple more rounds and get it within 0.2-0.3g or so?
You are not suposed to touch the countherweight in the armonic balancer! in case it has to be replaced. You did not show what was the radious on the machine. Waist of time.
