lots of threads here,
can use stock 48mm tb, to adapt the fuel lines most run out the back of the hsr. An6 to stock hard lines that are
more forward. Just run to bulkhead then along the frame rail.
fragola and earls make the Saginaw to an6 to convert your hard lines.

Ypu have to use Holley rails or pro comp if you can find them and a external regulator.
holley has the regulator on the rail.

Re: tpi to hsr manifold

Probably going to need tuning as well, particularly on the accelerator enrichment.
