I have a really nice holley 3310 750 vac secondary carb I am going to try out. I don't need to spend any money to try it, which is nice.
How good will a .550 lift, 240 @050 duration cam idle? I don't want to go over the top here.
Try the carb and see what you think. Check your plugs to be sure that it doesn't lean out at the top end, and jet it up in the front a bit just in case.
I would probably recommend a F238 Crane solid cam, but since the car is mostly street driven, they've got a very similar cam in a hydraulic part. The main difference is in the ramp rates.
I've had good luck with the 3310 carbs, but I do a good bit of work to them. The biggest thing that I feel is necessary is switching the secondary metering plate (fixed jetting) to a metering block so that you can tune the secondary jetting. However, in an open plenum inlet world, it won't be such a factor. You may just be fine with it. A 650 DP is a good choice to test if you can find someone who can loan one to you.
The more effort you spend in making the car go straight quicker, the less streetable it is going to become. You need to decide where over the top is fairly early on. This is one of the reasons why the low-cost plate nitrous systems are such a strong seller. It gives weekend racers a chance to go very fast (relatively speaking) on the weekends without much modification to their streetability.
