i have built 2 cars a duster and scamp both times i used stock v8 k members with spool mounts fit no problem i did have to clearance driver side shock tower a little to clear fender well header tube
Yeah I was asking them if they had a bigger crank pulley in the aluminum but they didnt they do have a stock pulleys 6-7/8 diameter so I went with stock 1-1 ratio
Update I got some stock pulleys from the junk yard the same size went for a ride it got up to 200 at the lights but as soon as I left the light the temp went to 195 quickly as before It wouldn't get below 210 unless I went a couple miles down the road with no stopping
