Finished up my timing chain project on my 1975 440. The car now starts on the first spin (3-4 times in a row so far and the engine almost jumps to start) and no white smoke or flames coming up through the carburetor throat. I wanted to thank everyone on this board (and my race car neighbor) for walking me through this project with their experience and pictures. I couldn't have done it without you and this forum. Thanks to you guys I saved $1500 that my mechanic wanted. My only regret is that I wasted so much time thinking that the starting issue was due to the carburetor and not the timing chain. Anyway, thanks very much. Paul
