I have for sale a full conversion kit to fit a chevy v8 into a mazda rx7 fd3s. This is made by grannyspeed and i believe they went out of business so a rare chance to grab this.

Kit includes the subframe and engine mounts
Trans cross member
Prop to fit the stock rx7 rear axle with yoke on it for a 4l60e transmission
Torque arm front to back.

This is for Gen 1 sbc engines so everything upto including LT series engines. If you want to run LS engines you will just have to modify the subframe mounts as an LS engine has different mounting locations to pre ls sbc engines. So there you have it if you want a 383 in an rx7 you need this.

Cash on collection from sheffield altho i may be able to deliver
