The figures I provided were the thrust sides. The thickness between the bores was less. I’m out of town but when I return I will post the sonic figures. That’s assuming I don’t need to recheck after testing again a “standard” as previously stated.

Again, thanks for all the input!

New to the forum but not FEs. That said, I’m 30 years out of date on what the hot setup is. Great website and I’ve already spent 20-30 hours of reading; truly fantastic information!

Goal: Hot street/cruise and some drag use in a 1966 Fairlanes GT. Goal of 600-650 HP driving a dual disc, TKX, and 3.91+/-.

I’ve had a 427MR staring at me on an engine stand for decades. That needs to change. It’s a loose 030 over (old school TRWs). I borrowed a friend’s sonic checker and measured the block at 1” and 4” down the bores and the thinnest thrust wall is 0.180” with most in the 220-240 range; it not a problem to take more measurements if there are know thin spots.

I’m astounded by all the new technology that is available and at affordable prices, compared to the old days. The TFS heads seem to be the current choice for hot street as does a hydraulic roller (spec TBD). A Scat 4.25 stroker seems like a no brainer but is there an advantage to a 4.125? H or I beam rods? Mahle pistons (my shop neighbor swears by them)? The TFS R-Series 2x4 tunnel wedge is a look I like but will it complement the above? I’ve had #40 flywheels in the past but now I see 25-28 steel ones are available which should be sufficient given the increased torque.

I understand the chassis will need work as well but am I on a reasonable path for the engine? All input appreciated.
