I Need help 410 Stroker timing Carb Education

I don't think the torker intake will accept a spreadbore carb without an adapter.Nothing wrong with doing it that way.I would expect most people to recommend a 750 double pumper in your application.If you have the hood clearance for a spacer and want to try the 800 then go for it.

I would think the magnum head wouldn't necessarily want 38* but I am far from an expert.
