PM David Claflin and/or Mr Blue. This sounds like something they'd use.

Sounds like a very robust short block that is going to have some serious power put to it.

I'd go with the cubes simply because it's easier to swap the heads, intake, and cam then pull the motor and have a 408 built down the road.  Should equate to less down time as well.  The 3.55 gear should be fine with the larger cubes too.   Also, those heads aren't all that tiny for a low rpm driver 408.  Ideally, you'd want bigger.  But, they can work fine and make good power for your application since you already have them.

How you drive it may be a problem!  You don't want to end up in a ditch or a wall.  Each build could potentially make way more than enough power to get you into trouble if you over drive it.  The back end can swing out QUICK and send you in a direction you never intended.  I've had a close call up a freeway onramp going WOT and hitting an unexpected bump on dry pavement with a much smaller motor.

The transmission may or may not survive.  I might if you have a regular street tire on the back and don't get stupid power shifting it.

The E5 heads look to have the same valve size as the early 70s heads,I knew there was a set  made in the 80s to avoid but could not remember what ones.

Ditto, the 1986, smaller chamber and deeper dished piston, same 9:1 compression, E6 heads.

10.75 to 1 compression should still run ok NA and nitrous but be boost ready for the turbo upgrade in the off season. I will be installing the turbo cam also now which will definitely not be ideal for NA with a 115 LSA lol.

Other than combustion chamber size, they are pretty much the same.

The E6 heads are the ones to avoid.

Bought some 351 parts to get a Duraspark distributor and a pair of E5 heads came with it,the E7 heads that came on the motor I have have some bolts broken off in them so I was wondering if they are similar to the E7s or should they be thrown on the scrap pile.
