1971-521

I have most of the parts I need to do the lz, just not sure if the tallest block will fit under the hood... Guess I'll just have to try... the easiest would be to do the z22 engine and transmission, but I want the car to be closest possible to the period it was built, and L20b engines are completely immpossible to find here in Norway. Also want good torque, and an engine that relates a little to what they did to the engines in the 70-80's. Sss head and double 40's is a good start but the Naps-z head is to new. Might have to lighten my wishes for the truck to finish the project... didn't know the 521 also had a 190 rear axle. Havent picked it up yet. Thanks for the information, will mate it with the 720 guts.

Thanks for all the helpful answers guys! Haven't desided on a transmission to use. Will the 5 speed from the 720 z22 fit? Should fit the engine... Also wondering if the rear axle will handle the torque from a 2.4 engine. Guess the axle from the 720 is wider than the standard 521 axle. Will be using the rear springs from the 720.

Hi guys! I`ve been doing a restoration on a 71` 521 for some time now, and the body is getting there, the bed will be painted this autumn, and the rest of the car is also getting there. I will not be using the stock engine, which is a J13. I have a lot of parts from different cars. I have a Z22 from a 720 pick up. i have an A87 peanut head from a L16sss, and a pair of intake manifolds and 40 dellortos for the L head. The question is as follows, A friend of mine has a couple of Z24 bottom ends, one of them has a balanced crank, rods and pistons. Will there be room for the Z24 engine with the L head, underneath the bonnet?
