Which frame do you have? How much are you planning to invest? I would think your frame would be fine with what you have now, assuming you've added an engine plate? It takes quite a few dollars to do these motors up right. If you're looking to build a monster motor, then you will need to look at speed rated tires as well. There are several after market frames out there that people have built up for drags, but I've seen a lot if guys run stock frames. Just beef up the engine plate and get a decent set of tires. Just my opinion, but I'm not a race guy. You may need to give more information about what motor mods you intend to do in the future before they can give advice on frame reinforcement.
