Too much?

[bigdemo1]

Would w2's be too much for a street head?what would the minimum compression/cam be for a really aggressive street engine with these.I'll be starting my dart in the spring,I was looking at a 450ish stroker crate as I don't want to run the original 340,also a 3000stall convertor and 4:10 with 275/60-15's,maybe the four speed auto but I don't want to cut the floor,there are some very strong opinions on the crates andI don't want to get into that however I would like low 11's on a single carb,seems to be alot of people doin it.

When I first finished my duster it was a street car, W2 headed 360. It made right at 510HP on our dyno in pump gas form.
So no, W2's are not too much. Alot depends on the porting. You can really open them up and make them work well, but that's not realistic for what your doing although the big CID would make me lean towards opening them up a fair amount.
If you run an open chamber head, I would stick to 9.5:1...if you can find a nice set of closed chamber heads then I would say 10:1 is doable with good tight quench unless you plan on using a really small cam.
