I met this guy last night. A real douchebag. I was on watch last night and reading Motor Trend. He comes up to me to ask what I was reading. I showed him. He tells me about a 70 Mustang he has at home that's putting 800hp to the wheels. I was like oh really? He also said he had a 351C built, sitting in his garage at home. He claimed 600hp. He said he had a chance to get a Windsor, but he said he'd rather have the bigger displacement. WHAT?! I told him a 351 is a 351. He told me the difference between the two was the Cleveland had a larger bore and longer stroke, the Windsor is a truck engine, and the Cleveland was built for racing. I told him the difference was in the heads. He said yes, but also in a displacement increase, and that Ford just didnt advertise it. It claime the 351C was the same basic engine as a 390. I just nodded and said "oh." He told me he found a 70 Shelby GT350, good body and frame, but the engine was toast sitting in a yard. He wanted to use it for his buit 351C. He offered the man $10,000 but he turned it down. I said $10,000 is a lot to pay for a rolling chassis, and that you'd be better off getting an standard Mustang frame and not waste a Shelby. He siad he wanted it for the suspension. I said, "oh." He decides to start talking about his 87 Camaro 2.8L. He told me he hopes to get it in the 13's. I told him its very unusual to build up an old V6. He agreed and said he has a buddy that has a twin turbo 2.8 Camaro. I aksed him how he did it. He told me his buddy had it all fabricated with 2 (yes 2) intercoolers. 1 per turbo and a Y-pipe connecting them into the intake. Again I nodded and said "oh." He THEN said he wants to do the same thing to his Camaro but just using one turbo. He told me he had a pair of Hooker headers that were going to feed into his turbo. I told him "wouldnt you need a turbo manifold, headers dont work with turbos." He said that the same guy who did his buddy's is going to fabricate a y-pipe to connect the 2 headers to the turbo. "Uh-huh." He starts on about his rear end next. Said he just bought a posi-rear end. I said, "Oh, you mean a limited slip." He said "No, a posi." I told him its the same thing. He said the posi locks the axles so both wheels spin equally. I said, "that's a full locker and thats great if you're looking for off-roading or straight line performance, but you won't handle for *****. A posi or a limited slip will let both wheels spin at different speed with power going to both of them. You need the outside wheel moving faster than the inside wheel if you want your car to handle." He said that a LSD slowly tranfers power to the wheel that's not spinning until they both start spinning. Confused I asked how the posi works then. He said he didnt mean it locked completely, but it allows the inside wheel to do a quarter turn ahead before the outside wheel and that makes for better turn in.
