Edelbrock LD4B ?s

I don't know why they put that extra hole in there as there is a plugged up vacuum hole right next to it.... :banghead:

Also keep in mind that there aren't any mounting bosses for your coil, like on a stock intake, so you are going to have to find a way to mount your coil.

I would go for at least 3/4" depth for the the thermostat bolt holes. 3 threads doesn't sound enough to me, especially as the first thread or two is usually slightly tapered and can't hold as much force as the non tapered threads. :rambo:


They are great intakes for the street on a little small block. :thumleft:
