Quote: Its gonna matter on the cam... being that those are iron heads you MIGHT be close but the cyl pressure will tell the store... what is the cranking pressure and the cam specs... if you cleaned any sharp edges in the chambers that will help... also if you can run the coolant temps lower that will help
I wish I could run lower temps but after heat soak and extended run time, 180-190 is what it is. Last time it got a cranking test it read 180lbs. Cam is an XE284 hydraulic. Also sisnt mention I have also swapped to a 6spd and before that detonation wasnt audible because of the converter and less load on the engine.
