    Aftermarket block street strokers.

    At a 4.250 stroke, I think plenty of power can be made for most purposes.

    Crane CCH-312-2-NC

    With 3.55’s. It’ll be sluggish off the line and have what seems like a slow climbing tachometer. It’ll feel like a slow motion jump that just keeps on going up. You’ll wait a while for a gear change BUT will notice that it happens much later on the MPH read out. Your top end will seem like...

    SV = Super Victor. I’d say, LMAO, YEA!!! The M1 is what it is and made back then.

    Starting a BB Duster project

    Hey Andy, I just wanna say thanks a whole bunch for detailing that car here as well as the other places I have seen it pictured and talked about which I thought was way cool. Showing the build here really was awesome. A big huge THANKS! To you for all of that time and effort. Rob

    Tunnel ram or no tunnel ram...

    11-1 might be technically low for the cam but I wouldn’t give a crap since it’ll run on pump gas and like race fuel at the track a bit. I have indeed noticed the runner lengths and have measured them on most of my intakes. Single plane only. MP-W2 on the shelf w/some markings. Plenum depth as...

    The super short runners scream high rpm.

    Do ether or…. Run the stock head with a valve spring swap Or Grab a set of ether Stealth or Edelbrock heads and run them. Check your own head by filling the ports with alcohol and see if the fluid level goes down in and past the chamber. If it leaks, machinist. If the don’t leak, run’em.

    That’s true generally speaking with a slight fitting advantage to the low deck. I did like my 400 in my ‘71 Duster. Lots-O-fun!

    Whooooooooaaaaaaa You need to look at some pictures because the Stealth head looks very much so like a stock head and the Edelbrock is very obvious it is not.

    383 power upgrade help

    Humm, that’s weird because 2.19 + 1.76 = 3.95. 4.320 - 3.950 = .370 4.250 - 3.950 = .300 Not enough room for a 383 bore? Makes me wonder where the valve are sitting.

    Thanks for the video link because I don’t keep in my head what other people do. Famous or not. I have my own crap I can’t keep up with! :lol: I thought I seen TF make a mention of a minimum bore size. The lack of a mention of a certain cylinder head casting number doesn’t mean it won’t work...

    Does anyone know if the Trick Flow heads will work on a 383?

    383 power upgrade help

    Yep! HP is a little low. Just add headers, change the intake (yes I know he has a rpm already) add a 750 carb and cam accordingly. It’s wake up time for that mill.

    383 power upgrade help

    With the OD ratio and 3.55’s rolling on 28’ tires, do you know what rpm that translates into @ 70 & 80 mph? Do not angle mill the heads! Just mill the deck flat. @PRH , the below, can you comment on the Stealth heads as cast vs the 440 source CNC ported versions vs your take on what can be...

    See if you can borrow one or have a friend over to check it before purchasing one for just this alone. Is your trans an automatic or manual. I thought I read manual before? Freeway traveling? At what speed?

    @Joey N When you said you have flat top pistons, the stock engines came with flat top pistons a lot and performance pistons are also flat top often but the difference is the performance pistons are often taller for more compression. They also have valve reliefs. What are you thinking power...

    440 source heads are chink heads. Edelbrock are made in America. Once the cylinder head and head gasket are off, you need a magnetic bridge and dial indicator. Zero out the gauge like pictured below with the gauge set low in the bridge for full plunger extension ability. The. Slide it over the...

    Afford the best cylinder head you can and top it with a rpm intake (For the street) and a 750, add headers. Where do your pistons sit in the cylinder? How far down? This is a key item to know. This could help guide you to the heads cc chamber amount. Your bore size maybe a limitation to valve...

    I hate to sound like a dick & I don’t want to come off as one, but here but here we go….. Your 1st question was very general, general answers given. Your second question was a little more focused but it’s still in a wide open field. So I explained it. Your third question is more focused but...

    Mopar Stage VI 6 heads questions

    The amount of valve lift it can take is related to the valve length used combined with the spring height, retainer and the valve seal height. I’m sorry that wasn’t specific but the parts used on the head can vary a lot. I don’t know about rocker offset. I’d say yes to custom length pushrods as...
