273 hop up help..manifold carb etc!

The old LD4b Edelbrock intake has been rated as the best for a 273. They have been out of production for years but show up here and E bay from time to time. Many of the intakes have been on many different 273's and then the owner desides to upgrade to a 318,240,360 or stroker. Nothing wrong with a 273. I love the spirit it has for being such a small cube engine. tmm
