Im looking for something that will handle 1250on fuel and 1500 on nos will a 5.9 block on a single handle it or should i just go with a sleeved 6.7 and make a 6.4
Neither a 5.9 or 6.7 block would handle that imo. Not reliably. I mean nothing is real reliable at that level but you know what i mean. Fleece/freedom has been doing the 6.4 for awhile
Agreed 6.7 isn’t a good option either Hamilton block or going with 6.4 I seen a lot of variables some not lasting .If cost isn’t the factor deck plate it
