i've got an 84 monte ls v6 that im wantin to put a 383 that ive built in it. What all parts need to be changed to put it in...

 

what V6 do you have in it ? if you have the chevy 4.3 or 3.8 or 3.3 you dont have much to change as the motor mounts are in the good location.the trans behind it will bolt on to the motor but probley not last too long !
and if you have the buick 3.8 you will have to change everything the motormounts are at the wrong location the trans will not bolt up (unless you have th200r4)to the chevy pattern.
you will need a v8 rad shroud and a couple other odd's and ends but fairly str8 forward swap
good luck
