Alright, I'm here with Perry from Mass Motor Sports. Perry, we got this motor in here, it's wired, it's pl Tell me a little bit about t Man, basically it started its life as a bare GMLS 7 block. It was new out of the crate. It's We freshly mac The block basically goes with one guy from start to finish, so he'll take it out of the crate and your engine when it's built, it's done by one person. Straight from the engine crate to the dyno. So, it's basically our run of the mill 427 LS7 short block and we topped it with a set of our LS3 280 heads. What did it make on the dyno? It made just over 700 horsepower and right at 600 foot pounds of torque. I peaked right at around 7200. Cool, that's probably I doubt it. What kind of compression does t It's right at 11. 5 to 1, so it's real p Yeah, I'm looking forward to it. What's bore and stroke on t It's a 4130 bore and a 4 inch stroke, so it's a 5,000 over bore from factory. From the factory all the 7 specs? Very cool and it's all forged bottom end and all that kind of stuff, all It's got a Kali's CompStar crank and connecting rods and the pistons in it are from Molly Motorsports. Cool, all the good stuff. All the good stuff. What are the head specs? It's a 280cc intake runner with a 2250 valve, 1600 exhaust, 70cc chamber. What about cam specs? Cam specs, it comes right in at 240 at 50 on the intake and 254 on the exhaust. It's on 111 lobe separation, 4 degrees advanced. Intake lift is 648 and exhaust lift is 630. So it's got a decent little cam in it. T Yeah, it should be. Now, I hear t It's been around the block, so to speak. Yeah, so to speak. It's been around the block. It started out as, We ended up tearing it down. We built the new engine for one of our employees, Damon. He put it in I did some drag racing where we could, Sure. You ended up selling the Malibu. We took it out of the car and we rebuilt it and gave it to Detroit Speed to run the One Lap of America with. Oh, right on. It was in there 2010 Camaro. So that was real cool. And then when they got done with it, we rebuilt it and gave it to Hot Rod Magazine to try out when they did their t So cool. And then it came back to us and we freshened it up and here it is. We're carrying the torch. That's right. We'll kick it off with a good burnout and then we'll put some serious smiles onto t It could be a lot of fun. We're looking forward to it. What do you say we get out of the way and let these guys finish up and inspire t Let's do it, man. All right.
