Comp cams xe268h for 318

Here's your answer on a low budget. You will install the rear end eventually. Why not now? A teen with a 3:73 willburn tires for a city block. You might not get 20mpg/Hwy so don't expect that. There is no magic bullet here.
Ok so let's go with that then I will keep the cam I have and install it and spend the money I would have on a different cam on the rear axle and look for deal on a stall TC. Maybe even mill the heads a little bit to add compression if I can scrape the money after the rear. So I have a few questions about the TC and the rearend. First the Tc this is going to sound stupid but I really don't get this so please yell at me lol. My stock tc has teeth it for the starter to engage. I was looking at some after market tcs and they dont have the teeth on them what am I missing there do you have to buy a plate or something to attach to it ? Second has anyone ever ran a 8.8 without narrowing it? And I asked it ^^^^ but I will ask again what is the average cost for milling a set of heads ?
