Well, this combo is now (probably on this run too) is dead. Two cracked cylinders and all six pistons were cracked. Not sure how long it was this way as it never lost oil pressure or smoked etc. I noticed some milkshake looing oil on the breather grommet and thought a head lifted. When the heads were off spun the crank and saw cracks. I'm getting that block bored and will do a stockish build and put it on a stand. I'm doing a TA block build to replace the stock block. I've never driven on a full slick and hope to accomplish my goal on a 255 with a stock rim. Love your cars! I'm a Limited guy all the way.
