    The more you show of this, the more I want to do that 440 I told you about. That clearance scares the crap out of me enough to say that were it mine I'd be going the route danlynch3993 did and girdling it with studs. You'd be absolutely shocked how much these blocks flex and twist when under heavy load. I've tried to call that fact out a few times and people mock the hell out of me for it until they do their own diligence and see for themselves. Would help with that pickup tube mount too. On that note I encourage going that extra inch and just welding a tab onto the windage tray ("its harder to put material back than to take it off" thing).
    No matter what though, this is definitely scratching my itch for want-to-know with the stroker kits. Thank you for doing these!

      Thanks brother. That tab has bothered quite a few. If I can get my tig welder fired up, I will do just that. This engine will have a nice hydraulic roller, that will be done around 6,000 rpm. By that point, it will have made over 600 foot pounds of torque and 550+ horsepower. It’s going in an 80’s d100 for a friend. The guys I’ve talked to that really run their strokers, don’t run hurdles until their over 650-700hp. The added clamp of the arp bolts will be help on the crank. I agree, the caps can walk.

    Hi Joe. I have started to look around for a low mile B-body, probably a Cordoba -they are out there and currently very reasonable compared to some of the Dodge/Plymouth cars. I reckon an ideal engine for a car like that would be a stroker similar to this build, so this set of videos is very interesting. I wouldn't really want to compromise the car's smoothness or quietness, so I think that I would build it for max torque at about 2800-3200 RPM and a redline of about 5300-5500 RPM, looking for 475-500 HP. I think with a 2500 stall converter and a 3.23 gear that would be a really fun car.

    • @JustMoparJoe
      @JustMoparJoe  Рік тому +1

      That would be awesome Gavin, but why does it need to be a stroker? I just put out the first dyno video for my stock stroke 400, with .030 pistons, edelbrock heads, and performer rpm intake. The engine made 520 foot pounds of torque and 510 horsepower. It’s 10.1/1 and very pump gas friendly. Check out the tunnel ram dyno video today. It makes even better numbers!

    • @gavinmclaren9416
      @gavinmclaren9416 Рік тому

      @@JustMoparJoe I hear you Joe, and if I do latch onto a sub 20 (less than 20k miles, less than $20k cost) car with a factory 400 engine it would be pretty tempting to do a 400 based build. Pump gas friendly is a must (pump premium is ok), but so is 19 inHg of vacuum at idle (more or less) for power brakes and other accessories. How much vacuum does your 400 develop? I want it to have a smooth idle. Choppy idling cars sound great but not for this one. In fact I want the car to be like it would have if the engineers weren't limited by emissions and CAFE, or in other words like it was a '65 instead of a '75, except even more torque for fun purposes. I think a stroker, either 400 or 440 based makes it easier to do. The key to all of this will be cam selection, and I reckon more displacement allows a bigger cam without compromising vacuum.
      Don't get me wrong, I think the 400 build was great and you are getting excellent numbers out of it, but it is for a drag car. I have often wondered how well a 400 built like a 383 magnum/roadrunner engine would have performed if it had been introduced in say 1969 instead of '72, and your 400 build sort of answers that. I am eagerly awaiting the tunnel ram power numbers as well as those of the Holley Street Dominator.

    • @JustMoparJoe

    Another great video, Joe.. I have to say though, I am not crazy about that bracket going under the main bolt... I would go another direction and weld a strap from one side to the other on the windage tray to get a very sturdy mount and then probably weld a bolt head to that strap and then use the 90* bracket with loktite on the bolts/nuts. Also wondering how lucky you will get with the pick up getting tight in the block in a good place!! Also, zero deck is as far as I would ever go. Who knows what the next build will be, but taking it lower typically means more issues than anyone wants... I totally get it. I'd want at least 11 to 1 w/aluminum heads.. You can still run pump gas at this point... Oh yeah, I am wondering what K-member you are using that allows that rear sump??? Maybe you've covered it before and i am losing it..

      @@MrDeeregreen I don’t think the deck grows after assembly or anything. The blocks have been “seasoned” for the last 50 years in and out of running vehicles. I believe they could have moved or warped after 1,000’s of heat cycles, after the factory. But once machined now, they are pretty well where they will be. If a block needs rebuilt after a while, typically the cylinders can get a simple rehone and send it.
