mate if i can lift one but not the other then they weigh differrent...... proof enough for me. (long bare engines, maybe loaded with access they are heavier)
if anyone needs a newly built 300rwkw CA (long motor) i have a spare one... oh and a fully built SR filled with Trust cams, rods and pistons out of cats car (just had re-fresh) and a Forged (arias) SR20 also fresh.
