Camshat/trans/gear combo 360

I highly recommend that you dont buy a cam until you know the c/r.
-Then figure out the latest intake closing point to get your dynamic c/r to where it needs to be for your fuel and intended useage. Then figure out how much overlap youre willing to suffer with. Then add up the numbers to arrive at intake duration. Add 5 to 10 to that number to arrive at the exhaust duration.The smaller for headers, the larger for manifolds. This is called, back engineering. Now go shop for a cam that meets the numbers, with the fastest rate of lift you can find.Or get one built.
- You cant just poke a stick in there and hope for the best. Unless you are rich. Or have nothing but time.Or dont mind doing it over and over.Well I guess I should soften that statement;IMHO its best not to just poke any old stick in there and hope for the best.
-BTW, that 292/509 demands some decent compression. Like 11/1 or better, or it will be pretty soft below 2500. Which with your combo will work, I guess.But its a real trick to tune, for a streeter. I ran it on the street in a stick car with an 11:1 starter gear. I didnt like it much. When a young guy came along and heard my story, I sold it to him. Good riddance to that stick. Sorry. I didnt find it M/T friendly, nor street friendly.BUT; that was a wicked sounding cam at idle, and it pulled forever.I shifted at 7200, but that cam I think wasnt done yet.
-I love that Dart body style. And I really like the looks of yours.
-I bought a 70 Swinger 340 back in 70.Panther Pink stick. I loved that car. Didnt handle very good though.Got me into a lot of trouble.Ahh, the memories.
FWIW; that 292 cam will need; some honking big tires, tubs, springs, and axle-wrap control.It will get that Dart into trouble in a hurry, so budget big brakes, big T-bars, and a full suspension overhaul, and frame connectors. Also on the list are bigger fuel pump,deeper pan,a cooling system inspection/overhaul,a high power ignition system, and seat belts. Your car may already have most of this stuff on it, I dont know. I just see smallish tires and flattish springs with a bit of lift going on.That cam is getting serious.
Good luck with whatever you choose.
