building a short rod big stroke motor

[axam48ida]

I have some parts I have been sitting on ....Let's start with a 86mm crank, type 4 mains.
with porsche rod journals. rods are carillo's in short 5.352 length
 Next is a case machined for crank and 94's barrels. I some old welded and
early street elimilnator heads which are cut for high compression (I don't remember the cc's) but the last
motor they were on had 13 to one compression.
Well, I like to hear some suggestions for heads and cams. I like to autocross this motor
so any suggestions

Er, an 86mm crank doesn't make it a short-stroke motor – just the opposite!
