You may need to adjust length on the wiring harness,and remove the fusable link if going to HEI.You'll need brackets for the accesories for the BB since they'll be different.

thanks,

I think we've got this covered too. We changed the six cyl to HEI last year and the BB has a pretty cool March sepentine pulleys and brackets.

WOW if that truck could speak it would scream, that truck is not going to know what to do with all that power. you sure will find any loose parts when you fire it up.
