Have a Wolfer copy of a SWTD.... Built strong for its use, has all the modifications for its year and a low pro R intake. On mine, Jack modified the intake for a 4 bolt loader versus the old school 6 bolt shovel from back in the day.
Yours is a copy of a v bottom Southwind or Hondo or all the others that were out at the time. If its built like the SWTD copy, then should be good in my opinion.
Enjoy.... !!!!!!
