hi there just woundering if the pre 60s mel were the same block and were bored different would parts from my 410 enterchange with the 383 and 430 gaskets whatever heads can i bore mine to a 430?

The 410 (EDH) (unique to EDSEL) Bore And Stroke: 4.20 x 3.70 in. (same stroke as 430) CR 10.5:1 345HP @ 4600RPM has a unique bore as the 383 (EDG) and 430 (EDJ) had a 4.30" bore and actually shared the same block (58/60) (See Engine Specifications in earlier post).

You would need to have the 410 block sonic checked to see how far out you could take it. If increased CID is desired, it may be best to look for an early 383/430 block (check previous posts here for mounting pad locations on early vs. late MEL blocks).

I have not verified this but supposedly the 410 used 383 cylinder heads for assembly (as did the later 430 due to casting problems). Performance parts are going to be sourced from the 58/59 model years. After that, it was just simply power for heavy LINC chassis.
