STOCK 10 BOLT REAR END
It made 448rwhp on a dynojet and 418rwtq. My best pass with an easy launch (1.8x 60', trying to save the rear end) was an 11.93@119.6mph. It was a GREAT budget setup that put down a good number and it served me well for almost 20,000 miles. Due to a strange series of events it spun a rod bearing after sitting with for a while with a collapsed lifter. I'm in the beginning stages of breathing new life into it though. 2 weeks ago I dropped the engine and transmission out. In another week I'll be ordering the new short block. It's going to be a 365ci forged bottom end ironblock with some nice parts in it. It should hold 1000rwhp all day. I'm only looking to make 650-700whp on pump gas and maybe 850rwhp on race gas. I'll be installing a fab 9" rear and a new clutch after the engine, and then the turbo kit. The poor 10 bolt wouldn't hold more than 5-6 lbs of boost for long. I'll update this thread with more pictures when it's done.
