A 400 is great motor. With its larger bore, a stroker will take it to 512. A little bit more than a 440 stroker. I am starting to love my 400'S!
I’m not hating on my 400, I would just like to find & build a 440 for a hobby as a back up motor or stick it in my shelby Dakota and
Make something really stupid
I took the 2 barrel of my 72 400
Went with a TQ , headers, cleaned up
heads & a comp cam as close to the commando specs as I could get it.
I have no complaints at all.
It breathes & purrs real nice!
