big block or small block

How much power do you want to make?

What is your budget?

You can do a lot with a 360. If you need more power, there are many options, but they all lead back to question # 2
just want a good streetable strong car...360 has kb 107's and a new cast crank...i could go 202 intakes in the stock heads with a decent cam and intake...or a decent cam in the 413 with my 906's and a good intake..headers for either one...about 3500-4500 on the budget
