351 swap

[Ieatcamaros]

I don't know that you will make that much more power. Depends on if you gain or lose compression. If you didn't lose compression, you will make more power. Not a whole lot though. You have got some bottlenecks on there. For a 351, you really need some better heads. I am one to persuade one to go carb over efi. That is just me. Fuel injection is nice when the parts match. But you can build a carbed motor a lot cheaper. Even though you have most of what it takes to do it. An intake and carburetor are going to cost $500 at least. A trick flow 351 intake costs about the same. The difference in your case would be in the distributors. You can get a carb (not points either) distributor from the parts stores for like $50. It will cost you $100 for the fuelie's distributor. But when you go carbed, you have a lot more work to do. You have to take out the electric fuel pump from the gas tank and either make one or buy a new sump for it. Then you have to do all that wiring for the electronic ignition. Get a magnetic pickup(electronic in layman's terms) dizzy and use msd or the durasparkII. Then you either have to get the right timing cover and cam eccentric or use an electric fuel pump. Thats the most of it. Read here for more details.
