Original hemi dart information

I haven't had much time lately to visit this thread due to the time I've been spending getting my car ready for the season. It's had alot of upgrades since the last time I drove it a couple years ago when I bounced 3 valves off the piston tops due to 2 different deck heights. Leason learned---- NEVER ASSUME just because you measure one deck that both are the same height......... Even when both were freshly machined. Passenger side was .040" shorter. I purchased it this way a few years ago.
Forward to today. The elfunt's back in it's rightfull place finally. Should be ready to fire in a couple days.
I fiqured in the next few posts to give you a tour of what's being done to the car in the months previous of many hours.

The base for this build is an original 1968 casting 426 block & heads. Crank is a Crower 1/2" stroke with 2.200" rod pins so I could use the BB Chevy 7.0 Crower connecting rods with the small .990" wrist pins. Lighter reciprocating mass, less clearancing issues, & easier to get bearings for. It displaces 492 CI.
Compression was kept to 12.8-1, because fuel to fire it is ALOT cheaper than fuel needed for a 14-1 motor.( And it'll have way nuff power this way anyway.)
