    I coulda had a v8...........

    I've had this little D50 for a few years and been wanting to do this.......its a 318/904 completely stock but have cam/lifters, roller rockers, and eddy intake ready to go on but wanna get things associated with the swap sorted out first......so far this thing fits perfect except a little long.......I still have to pull it out and purty it up but mounts are built and its bolted in as of now.......

    Thought you were done with the T/A cars.

    So all along the plan has been to drop my 55 Dodge pickup cab onto this chassis so here is the beginning of that process.......some of you have already seen this.....I'm trying to finish a T/A restoration and then will make lots more progress but here is where I'm at for now

    A relatively mild cam can sound more radical if it's set in retarded. A retarded cam usually is louder in the exhaust too. A guy I know that went to the track for the first time had a problem with the car being way slow and being way loud couldn't figure out what was wrong. I told him what it sounded like to me but he chased his tail and changed everything including the converter before he finally stuck a degree wheel on it. Sure enough, the cam was way back. Initially, he installed the cam using the dot method. Most times you can get away with that but there will be a time when it will bite you in the arse. I even degree in a stock build just to make sure the parts are marked right and you know what, they are very seldom on the money. And it's not hard to do and the parts needed are not that expensive and can mean the difference between a good running car and one that's a screamer!

    I agree

    like cranky said, it might be advanced a bit much. BUT for what it's worth, when we took carbs off and went injected, no more lope, steady 1200 RPM idle and had a bad lag when I stomped on it (like going from one carb to a bigger one). we actually had to RETARD the cam 2 degrees and a little lope came back and the lag was gone. If that's of any relevence I don't know, you obviously went to more cam and carb kinda like my change. I'd damn sure get a degree wheel on it!

    Did you use a degree wheel when you installed it? You may have ended up with it advanced some if you just used the dot method. It's a toss up when you use the dots. The cam in my buddies Demon idles really rough and has no low end at all...but he used the dots and not a wheel. It surprised me that he did that because I have a wheel etc....

It's flat dead off the line but screams from 3000 to 6200. We stuck Mopar Performance stamped rockers, lifters and MP push rods in it and no have no problems running.
    Suprisingly the idle is almost completely smooth which is not what I expected with the lift and duration.......I'm assuming because the obvious slack in the valvetrain I'm not getting full lift or duration....?

    Looked at the vids & pics... the D50 should be fun runnin' for beers with

    You likely need new pushrods and stamped rockers because of wear or adjustable rockers and corresponding Pushrods.

    I'm wondering if the cam is cut on a slightly smaller base circle which would make up for the usually head cutting?? this would make wear in the pushrods and rockers much more relevant??
    But my gut tells me you ended up putting the pushrods with most wear paired with rockers with most wear! New set is cheap?

    I took it for a drive tonight and it ran good but the lifters are still rattling albeit not as bad. I guess its time for the roller rockers I have stashed away but need pushrods first. I've been fighting a leak but eventually found a crack in the intake but JB weld is holding at least for now. Must have some steep gears cuz the rpm's seemed kinda high but without a tach its hard to say.
