I have heard a lot about these kits jtr. Why do people use the kits, When I built our z car, I used a front motor plate, pretty simple to install, then a mid motor plate for extra strenght and support. Made my own cross member. Used the hooker headers super comp made for a z-car. It is not that bad of a deal to make.
Ist note, get the headers 1st, setup a dummy engine (block) with heads. position it with the headers on. This will let you know the rest. Where the crossmember needs to be, motor plate setup and mid-plate setup etc.
Maybe I am so used to making stuff, I take it for granted. We are working on the S10 build up now. Installed dummy engine, ordered headers. Have to wait for them to come in and mount them before we procede with making any type of mounts.
just my opinion, but you know the saying......
