I have a 5.7 350 in my 89 burb v1500. Im looking to convert it to a 4 barrel carb set up. Looking for suggestions, tips, and advise. It looks like the Edelbrock 2104 performer is the way to go for intake. I found an awesome deal on a Torker 2 bit it sounds like it won't fit the cast iron heads. Also advice on aluminum vs cast iron intake manifolds? I'm going to convert the top end only. Carb, manifold, distributor, fuel pump. I have heard lots of different options on what will fit and what won't. I have a budget of about 1k so I have been trying to find used items that are high quality. (Easier said than done lol) Thanks for any advice you would like to give!
