I ran 175 shot on mine, with 100 octane, and br7ef plugs, went thru about 10 bottles, no problems. Only had 2* timing cut. Never saw any knock, plugs looked great.

blown transmissions are about as useful as 97% of the guys on this forum
I had 175 in mine over the weekend. It was detonating but i held onto the button a little longer than i should have. Truck still runs good..lol. Im sure it will handle 150 with a tune no prob.

My 4.3 is still ticking along on a 150. Literally ticking, but it's still going.

Mine it ticking also, since the day i bought the damn thing
Mine's a direct result of spraying it though. Shitty gas, ragged tune, itchy button finger.
