Disappointed in my 383 on the Dyno

More food for thought. If you're talking about tearing this entire engine back down to the block again and having it reboard and buying a stroker kit for it and a new cam and new lifters???..
Again food for thought in my mind I'm thinking for a few hundred dollars to get a 440 block and start this process for pretty much the same amount of money and end up with a 505...
Leaving your 383 100% intact and either reusable or resellable to recoup... Also usable until the 505 is done... Then it's just a matter of switching out some exterior components, alternator... etc...
