70' challenger big block build
70' challenger big block build
I posted on here a while back and was happy with all the help I got so I'm sharing my current progress with y'all. Got my engine mostly together and will include a link to the pics. Please feel free to mention or point out any mistakes y'all notice so I can go back and fix them. Again I'm only 15. Thanks, I also included a picture of the car because some of y'all were asking.

I wrote a lot more detailed paragraph to start with, but then when I refreshed the browser after adding the link it deleted everything. The car was originally my dads and he had many different engines in it as well as customization on the car. As you can see its black on silver when it was originally sublime green with chrome trimming. He also added the spoiler out back. Don't honestly know if it was originally a 4 speed but that's what's in it now. My dad has died and left this car along with a 69' charger he got in the 80s for my brother. The 69 isn't cared after by him and is just sitting and it's a very nice car with a 440 and like no rust at all. But that's a different story. He left my challenger with a 340, which blew a head gasket last year when I first got it running. He had a big block 383 shortblock sitting in the Corning ready for assemble. Flat top Pistons that go to the deck, steel crank, don't have any idea on clearances. Put in a matching comp cams duel timing chain and gear for the 292 magnum I put in it. Heads are the closed chamber version of the I believe 906s..? He did work on them; put bigger 440 valves and before I put them done I had everything re-done with duel springs, valve job and hardened seats. Right now had all stock pushrods and rocker arms do to cost. The second I have a spare 800$ I'll have some Harland sharp rockers along with some decent pushrods on the way, prob comp cam pushrods. Bought a set of chrome hooker super comp headers I think the tubes are 1 3/4 with 3 inch collector. Had a Mopar m1 intake ordered but it's on national back order so I called up jegs and had an edelbrock torquer single plan on the way the next day. I have a melling high volume oil pump on ig, and milodons 7 quart deep sump pan with the matching pickup. That's about it for right now. Has been sitting in the corner of my shop covered for about 2 months or so now. Have added little stuff here and there. Painted all the brackets low gloss black along with the Saginaw power steering pump and have all that bolted to the engine right now. But that's about it. Right now my boss is helping me out by adding up a good 600$ worth of Checks and he is gonna order me a Holley dbl pumper to top off the engine. When I do something else to it or make more progress, I'll post it with pictures.
Yea I have the milodon 7 quart deep sump on it along with the pickup and then I have a melling high volume pump. The cam I have in it is a comp cams 292 magnum. (By the way, I'd love to hear what people have to say about it. Good power throughout the range? Bottom end? Redline rpm? Sound at idle?). I'm damn eager to find out. I'm worried about it going flat honestly. Had sat for a while and before I put the intake on which was about a month ago most of the assembly lube drooled off of the loves and was dry. I may say screw it and after I have the engine in the car like a day or so before I break it in I'll pull the intake off and Drinch the cam and lobes with some assembly lube then start it up asap afterwards. Maybe even the same day.
