I agree..run the 360 and have fun...yes I have a bblk dart but let me tell you when I 1st started my 2nd car was a 340 car and I owned several and played with the smblk stuff for a long time and I assure you a well built smblk will kick some butt and I still watch and listen and sometimes get the itch to have another one,some of the most fun I ever had was with a 71 dart with a 318 I had 'morphed' together ran 13.40''s and 13.50's was a fun car and couldnt kill it..not like the 440 I have now which I wouldnt trade but the smblks aint no punk,and since you already have a 360 which shares everything with all the other smallblks except stroke and bore you are already ahead of the game just need a few mods and upgrades and is a bolt in with what you have already,my 'opinion' if I were in your shoes and without the headaches with a bblk swap which to me is a wrap now but if you never done one before it can drive you to drinkin..lol..cut your teeth on that smblk and have some fun and kick some butt...
