I recently picked up a pallet load worth of y-block parts, including a short block and a bare block fresh from the machine shop), two pairs of heads (one pair ECZ-C has been cleaned, magnafluxed and all that) and a bunch of other useful parts like oil pans, timing covers, pistons, cams, valvetrain related stuff, etc. etc.



The other pair of heads have ECG-T cast into them. I looked on Mummert's ID chart and found nothing about ECG-T heads...



Anyone know anything about these?



Thanks --Matt
