i was woundering if anyone could tell me what rear end gears shall i install for all out speed....

Any gear from 273 to a 308 would give more top end speed than you would probably ever see. I had a 68 firebird with a big cam 350 engine & it had 273 gears. It didn't get going until 35 mph, but it registered 160 and I put it a little past that once. I raced top end almost every weekend & this car didn't know when to quit. It would cruise at 145. I'll give your fair warning, however, that was 15 years ago. There's a lot more traffic on the road now than back then. All my racing was done in the middle of the night on desserted roads & I could talk for an hour telling you stories of close calls. I'm lucky to still be here. I pulled the 350 & built a 428 out of a 68 catalina. The engine put out about 475 hp at the flywheel. I used 342 gears so I wouldn't get killed. This car would take your breath coming off the line with slicks and still had a top speed of 135 mph. I didn't have any close calls with this setup because it would go from zero to 135 and back down to 55 before you ever met any cars. Top end will get you killed on the street, not to mention innocent bystanders. keep safe. jtyler
