my car is a 79 GP Lj. came with a 301 4barrel carb/th200m 2.29 saf-t-trac rear, with the optional handling package. I've since put a pontiac 350 in the car with a th350 trans with shift kit and 2200rpm stall convertor, 3.73 gears with the posi, gm performance big block springs up front with progressive rate springs in the rear. added those tubular bars that connect the cross member to the rad. support. Also has MSD box, custom shifter set-up, factory bucket seats with power drivers seat, power windows and locks, a/c, and it had snowflake wheels. more like an Sj, but it was the way it was ordered. Now it has steelies and pontiac dog dish caps. Currently modifying the cross member for duals, and working on the body. Very little rust, but some dents, awesome frame rails. Engine is a 71 block, with 70 #16 heads, 4bbl cast iron intake with a qjet, bored .030 over and .010 under on the crank. decked .010, heads were cut also, but i'm not sure how much. had to use polyloks to get the valves adjusted. summit cam...pulls really hard up to about 5200 rpms. lots of fun to drive. plan on doing the 12" rotor upgrade, trying to line up parts now. have a manual steering box on the way. after the duals i plan on getting a non a/c fan motor box now that those are available. anyway, that's my car
