Yes the stock Explorer GT40 and p headed engines are factory stamped 1.6/1 ratio rocker

Just make sure you are shopping for GT40 SBF with the 28oz external balancer and they will drop right in.
$6200 is quite a bit, but worth it to get a 347 with a warranty!!
It is also the reason I still have a stock 302 explorer longblock
Gotta pay to play

Factory Explorer blocks are not a bad choice in this day and age, 302 cores are starting to get harder to find = core value goes up and the explorer 96-01 are full roller (aside from stamped rocker) they have dual timing setup from factory, high volume water and oil pumps = they run strong and make good budget builders

I like these guys we have about 25K miles on one of their 302 and it has been awesome
