while researching my 396 build I read a good article on chevy high performance about a 396 sbc build & it stated that 4 out of 10 blocks fail the pressure test on a 408 build Yeah stroker rods & such will help but any way you cut it Its still a 4in stroke Find a shop that builds a lot of strokers

I have an ultrasonic thickness gauge but was trying to decide if i wanted to go 3.75 or all out to a 4".... block filling isnt a problem but if many haven't had to fill then i def will go 4".

keep us posted on how long it lasts. i have only read rumors that LT1s exceeding 396CI are not long for this world. i know of 2 local 396's that take regular beatings plus street duty that barely break a sweat so knowing those extra cubes are more than a novelty would be nice.

Some people say .100" is the min wall thickness, however if you hardblok fill it you can make the wall paper and still get "some" runs out of it.
Here is a few pictures of my 396, the machinist had some fun on the rail sides, you don't have to take this much out for a 3.875, but a 4" is another story. I believe this was done on a bridgeport.

Did you have any problems with using a pilot bearing/bushing with the crank? The hole for a bearing/bushing is oversized on the one I bought (problem with a batch of their crankshafts) and their answer was to use either a knurled bearing or an oversized bushing.

I can't remember what Eagle rods I had, but the place that built my block didn't want to use them and recommended Compstars. The rod bolt profile was significantly shorter and allowed for less clearancing.
