on the big block plates how many bore sizes can you use with one plate? my current stuff is 4.375, but my next one will be 4.5-4.55?
for engines up to 4.400 bore we prefer to use a different plate than we use for 4.440 up to 4.560 bores. in other words, one plate has 4.410 bores and the larger bore motors use a plate with 4.600 bores. the wall distortion is different between the two of them from what we've seen. the differences are enough to make it worthwhile to have both sizes available. please call me and we can talk about it. 561-758-6604 Dan
