Not Ranked
Don & Jeff,
Both of you are correct.Below is what Keith had to say about it.
Don has an aftermarket Dart block.
" 427 stroker
These stroker combinations do not work real well. We have had some sent in for repair. This is a 4.187 stroke with a 6.125 rod and makes for a terrible rod ratio. This is just to much stroke in a stock block. we do some 4.100 stoke cranks but us a 6.200 rod and these have worked out fine. We do a lot of the 4.000 stroke engines with a 4.030 or 4.040 bore for 408 to 410 cubic inches. If you do an aftermarket block and do a 4.125 bore with a 4.00 stroke this gives you 427C.I. but in a much nicer designed package. Thanks and good luck, Keith"
