I'm more of a Gen 1 3.0 man , but when living back in Kentucky we had to pass strick smog in the bigger cities.
I passed on buying a couple really goodlooking 4 bangers cause the carb's plastic body part would crack (,with the bad weather big fluctuating changes of midwestern x southern fronts thru tornado alley).
They wouldn't pass smog without a lot of rebuilds.
And the heads had a BAD reputation and the blocks on those counterbalance problems.(also check out www.jasperengines .com.( in Indiana) they re-engineer Known weak spots in engines and have a REAL good reputation,,, and they just opened a couple warehouses in the west.

The Heads ??? with all that oversizing the "Holes" , Ive heard they crack alot between "holes".
John Baker still has some Beefed up Heads on his list that don't crack.
Yous guys might want to check these out.
His place is now called TRUCK and TRACTOR and he's in Wicn. or Minn.
Better hurry , I get the felling he might be getting out of Monteros so better get his good stuff while you can.
