[QUOTE]Originally posted by Marshall Mathers: [QB] AFAIK, there is no 10 second LS1 cars in the norcal area. There are two that are VERY close, one is a purple camaro and the other is a silver trans-am... Ones an MTI stroker with NOS and the other is a stock bottom end LS1 with ARE heads/cam and nitrous. The camaro has gone 125 or 126 and so has the trans-am so the real issue keeping them away from the 10's is either in launching or tuning. The only green LS1 camaro that I know of that was even close to running 10's (well not really as he is slower than I am) was this old guy with a cane that had a bone stock LS1 with headers and some other bolt ons and had a WAAAAAY sweet Pat Musi direct port nitrous system. The guy looks like he's 80 years old and I'm surprised he doesn't keel over and die during a high 11 second pass (best pass I saw or heard about was an 11.7x@119 or so) But other than that the only VERIFIED 10 second 4th gen is LJ's green car. It's not his third motor unless you consider the motor it came with as the first. The motor was built by Blackstone (the first round of mods) It was a 351 (forget how that happened but I think it was a .010 over on the block) that used stock rods and a magged and polished stock LT1 crank with some low compression slugs (LT1's use 10.4:1 compression hyperutectics stock so more than 6psi of boost will destroy your engine) and he had some blackstone ported heads, big throttle body, and his Vortech supercharger was cranking 10 lbs of boost. His best pass before the "accident" was 11.28@128mph. He also kept twisting driveshaft yokes and doing random T56 damage before the big problem at the end of last season. Three rods decided they didn't want to ride any longer so they came apart and shot through the oil pan 3/4 downtrack. Oil and coolant went everywhere and when they took the heads off the car 4 pistons were turned 90 degrees in their respective cylinders! It was ugly. So now Blackstone redid the motor to a 383 from what I'm told and he's running forged everything, more boost (I'm told 12 or 14psi) and a Vortech aftercooler. He's also running long tubes and some kind of snazzy valvetrain that's never been tried before that Blackstone needed to order specially for the car. That's all I know. Best pass so far was 10.87@132. He had to do some minor work but now the car is running again and he apparently run it at Sacto very soon and feels a 10.50 or better will be garnered. I'm thinking he's right with a 132MPH trap speed!!!!! That's damn fast. youl luz: Yeah you're right with 120+ trap speeds you're losing a whole lot of time out of the hole and then charging hard at the top end but by then the race will be over with a hard launching car that still comes on up top. I know you like keeping it a street car but why not run some small slicks like 26x10 ET Drags???? You can still call it a street car even if you run slicks. Or get some ET Streets for that matter. If you can crank off a 1.8 short which at your power level shouldn't be hard you could run an 11.60 or better. I crack low 1.6's to high 1.5's with a 4500RPM launch and I run 122 in the 1/4 so you're not that far off from my power levels..... [/QB][/QUOTE]
