I purchased a 71 240z in a basket that consisted of a 240 block bored to 86mm, 280 86 mm flat pistons, 240 rods w/arp bolts, a 260 crankshaft, and a E31 head, (Also came with an E88 head and a N42 head). 2 different cams (not sure if 240 or 260, and not sure how to tell the Difference visably). I did a 3 angle cut on the valve seats and used new valves in the E31 head. and a closed ratio 5 speed transmission, Using a 82 ZX distributor and SU carbs with SM needles. Engine sounds good and strong but car doesnt have a brake booster so cant really test drive to really tell. Until then im open for any ideas as to anyone know how to visably tell which cams i have or any suggestions...... Such as without a dyno any idea of HP rating and if app im using is correct on CR of 14.44 ?
