Hi Again - I just lost my job so money is a issue - I can get a nice motor the whole thing for around 900.00 - if I go with 904 don't they have trouble finding gas - 11.5:1 compression? Then new clutch kit on and on.....then better manifolds on and on -- thinking pull top end off then stick new one on? Any suggestions? Any place to send to rebuild? I bet if my jugs are out of round I be boring them though- aw man what a mess!
