Hey all,

well it happened. The old 78 12a ( the third motor in this chassis, the first of course was the stock 12a which the previous owner tore out for a 13b which he then blew up. after that he put a new 12a in because the old 12a disapeared, go figure. then i got it) has died https://www.nopistons.com/forums/pub...O_DIR#>/11.gif . However, I got a new motor from Rob at Pineapple Racing and am in the process of getting it ready. No its not a 13b but, i am setting it up to what i think will be a fun car. below are some pics and a list of mods, tell me what ya think.

lookin good. it's gonna be nice when you are all done

I am trying to figure out what killed my old motor. a 12a N/A shouldn't have gernading problems but that exactly what happened. The front rotor has a blown apex. broke itself perfectly in half. go figure....

Thanks for the replies so far guys. I am a liitle worried however about the new motor and the old carb. How am I going to tune it? Should I go DYNO or should I feel it out? I do not have a gas analysing system so I am up for suggestions.

how many miles on it? they do sometimes just die of old age

You see that more and more with 12a's.Its too hard to kill a 12a.They just don't die that easily. https://www.nopistons.com/forums/pub...1047683358.gif
