Where are you at with this build. I am building a 69 428 for my car using 16 heads. The motor is in assembly stage. I went with a comp cam extreme energy 268 cam, 224,230 but on a 112 lob separation. I went with a 9.5:1 compression ratio. I have been kicking around using the long branch manifolds. Not 100% sure I can pop for that, but would like to. Do you know what you have in the build at this point? I am up around $2000 for parts and machining. Have more in the block and heads. This is getting expensive, but I think it will be worth it.
