Noc bit late, but there was a compleat 1250 hammer kit with motor thrown in at a good price posted in here those barrels would fit your motor & had the 1200 late model EFI heads and performance clutch the heads still had stock chamber, so could be used with any pistons that was a really good price ( if still there ?)
does not matter what you think, i would not bother with 1200 conversion unless i used 1200 heads as valve sizes & 1200 heads so much better the heads are everything! plus brand new performance clutch & engine hard to beat for that price
Hey MUT
Was about $2500 fitted, and I got a good chunk of that back on the SE Tuner included in the kit which I did not need. Read my previous post for more detail around my experience so far.
that was good of Hammer Howard!!
Hope it all turns out good!
