Hi FABO I'm finally putting this Duster build into a somewhat organized page ... thanks in advance to all that have helped with my novice questions. We bought these two cars in September 2014 and the plan is a cool Duster and to sell the Dart Sport. Both the cars have typical rust on the lower quarters, some slight trunk rust in the tire well and the Dart has it in the rear window frame. The motor that came with them is a 440 HP E ... cast crank but thats usable as Id like a mild 425-450 HP car. The rear ends are 8 1/4 which I'm ok with too as that can be streetable.

Delivery day...

Pulled the motor... Heads are 346 which are fine by me being open chamber for this mild build. But unfortunately the Ma Mopar induction hardened valve seats were not in that good of shape. Had to have a little head work done. Hardened valve seats installed, and new valve stem seals. Three angle valve job and a little machining on the deck surface. They still need to be finished and assembled. Valve springs are good at 130# pressure so Im going to run with them.

Valvetrain is stock rocker shaft stuff... rockers look typical wear. Im trying to reuse as much as possible

Pistons are a little low in the deck ( about .42)... I hear great things about the six pack pistons ( 2355)?. They are reasonable priced. I'm open to suggestions... Id like 9:5 compression.I don't know what I have now for pistons.

Nice little trays from Summit to hold goodies.. I like em. Not too sure I'll keep these stock pushrods. I'm planning on a .485ish camshaft and the heads have gotten a surfacing and I'm sure the block will need one. I'll measure for correct pushrod length.

The cam that came in this was a .509 and I was hoping to keep it. It had too much rust to save.

Thanks 70440! I'm having a great time and thanks to this site I'm actually learning things hahaa!
 
Welcome! You're off and running. It's a big project but the journey will be worth it in the end.
 
Good ole klean-strip and wirebrushing got the timing cover looking decent. Used Dupli-color engine primer to hold off the rusting till I get everything painted. Next the valve covers and oil pan.
