Should I get different fuel lines

Right now I have a stock 2V 351C in my car with the original steel hoses. I am looking to rebuild an engine for it with a 750 cfm Holley double pumper. I am not sure what size the hoses are, but they are original. Would these hoses be too small for what I want to do? Should I get larger ones? Where can I find them? Thanks.

If the engine is pretty mild, the stock 5/16" lines should be OK. If you are going to pump up the Cleve, you'll need 3/8" line. You should be able to get some pretty long lengths from the local parts store. Also buy a good tubing bender from Eastwood. Remove the 5/16" line and use it as a template to bend the new 3/8" line. You'll also need a sending unit with a 3/8" line, but I'm not sure who carries them.
If you want to spend some money and become NHRA legal, run braided steel line with AN fittings. Summit and Jeg's carry it.
