Need help with parts selections.

I took your advice and looked into the AFR 185 heads. Pretty impressive. The AFR heads flowed better than the Windsor heads throughout the curve and with smaller ports. World Products doesn't have published flow data on the Roush series yet. Comp Cams suggested the 35-442-8 roller cam. They also said that this cam has a flat torque curve maxing out at 3,800 to 3,900 rpm's. HP range is 2,000 to 5,800.

The AFR heads create one problem though. Since they are aluminum, what needs to be done (if anything) to the compression ratio?

What's your take on MercDude's comments? You can e-mail me at scottalanmiller@hotmail.com. MercDude, I am interested in your comments. I haven't decided on anything yet, and probably won't for a month or more. Keep your comments comming.

Right now the car has a 650cfm Holley with vacuum secondaries, single feed, and electric choke. I would have to trade with a friend for the 750cfm. Another option is to have another friend redo the 650cfm carb. He has a flow bench and designs carbs for a living. He rebuilds carbs on the side.

I think I will make a trip to AutoZone this weekend. I hope this software doesn't cost much; it would be fun to play with and learn.
