Chevrolet Truck Classifications?

impstocker · 09-24-2015, 09:25 AM

I found a thread in the Racer Build section on a "Peanut Port" 454 build interesting. With the numbers and RPM higher than I thought and rated at only 310HP and 454 CI my be a good combination after all. Drawbacks are the flat top pistons plus open chamber heads therefore the low compression ratio of 8.2

I have one of these 454 out of a some truck, can't remember. My question is how come only the 1990-1992 SS454 Pick up is the only one in the guide with the engine. I know they came in a bunch of other years non SS trucks? How come some years only list the S10?

Is there a process to get a truck/car listed n the NHRA Classification guide.
Thanks for any info.
Does anybody know if this combo came in any passenger car? I don't think so..
