I wouldent call them piles, but hardly efficient if you wanted to “build” them compared to an EFI motor. If I did not buy a 240/260 with a motor swap already done I’d just rock the Stock motor and rock it as a cruiser until I got the money to swap.
Skid, Im quite aware it costs money to do a motor swap. Regardless I don’t want to build one for power, I’m over wanting something thats ridiculously fast. It would be easier to swap in a and much more efficent to just pop in an RB25/26 or even some sort of V8 and get an easy 300+ whp than it would to do soe with the L28.
Theres a local with a built 240Z with an L28, makes a bit over 300hp with it, has to run race gas all the time and the motor is very temperamental.
