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.
