freaky-rx

hello, i have been looking around for a while and figured it was time to be a little more active. so far 3 yrs. ago i bought an 85 fb 12a model. the guy i bought it from didn't know why the antifreeze kept disappering. no leaking whatsoever. so far i left the motor alone and worked on the suspension and brakes. i have an se rearend and did the respeed big brake kit ( thanks billy!) and replaced all the bushingsthat i could for now. so the question is should i just rebuild the 12a or opt for an 13b? i would like to do this on my own but i KNOW I CAN'T do the motor myself. has anyone have work done at Pranther racing in kansas? oh yeah looking for around 200-250 hp. any info is greatly appreciated. thanks
