With a practical limit of around 300 ci for an inline engine that will fit in a standard passenger vehicle and the relatively low cost of a 400+ci V8 that will fit into the same space it is no wonder that we are few and speed equipment for our engines is scarce. When you can build a flock of small block Chevys for what one strong Chevy, GMC, or Ford inline six would cost it is no surprise that folks on a tight budget choose a V8. It's just the way it is. Less demand means fewer parts and higher prices. The 292 came along when the V8 mentality was firmly in place. I am amazed that there is as much stuff for them as there is and that a lot of it is so affordable. Very few car publications print inline articles and the newest information on 235/261 Chevys and 270/302 GMCs is over 60 years old. A lot of the guys who have newer info choose the take it to their graves rather than give up their secrets.
