    WTB Street Demon 89" primary jets.

    So, it looks like the Street Demon 89" primary jet size cannot be bought. (Comes stock on a SD 750cfm carb.) I emailed Holley and got a reply with a pic of a standard Holley 89" jet. Tried to reply and explain, but if its not on the website then it does not exist. (Like there isnt a box of them...

    In my build I have a 2.5" exhaust system with long tube headers. So evacuating shouldnt be a problem.

    Thanks a lot for all the replies in the thread. Now I am more settled of what heads and cam that I will need to order for my engine build. Time to rebuild and test a Thermoquad on my test mule engine thats in the car.

    But with 112 lsa? What would the difference in engine behavior be with those two cams? https://www.hughesengines.com/Index/products.php?browse=browse&level0=RC0gQmlnIEJsb2NrIChMb3cgRGVjayk=&level1=Q2Ftc2hhZnQ=&partid=30252...

    Thanks, that is some great info. Yep, the 440 stealth heads is what Im going to drop my wallet on. Im going to base my cam choice on recommendations in this thread and prolly go with the cam that 451Mopar posted. With this I will go to my Drag racing neighbor and ask for his opinion, he always...

    The Stealth heads would land me around 10.34:1 in comp. Well, I guess I just have to choose a pair of heads and go with it, whatever brand I read about it gets both good and bad reviews. Though, my whole rotating assembly is 440 source....

    So what heads would be a good choice for what I am trying to do.? The TF order was canceled so lets forget about those now. :lowdown: It seems like the E Street Eddys are no good? But I dont see that many other choices of BB heads with an around 84cc chamber.

    Thanks @Geoff 2 ,@451Mopar and @gtxrt for lots of Cam advice, learning a lot. :thumbsup: I would like to order some parts so my engine project can start. So, reading through this thread it seems that my choice of heads was not right for my combo. Now, a set of E-Street heads with an 84cc...

    #5 I wrote in post 13 that my heads order was canceled. So choice of heads are up again on the table. :thumbsup: Cam selection specs are still a maze to me but the replies here are awesome. Learning a lot.

    Small primaries, large secondaries combo. The younger cousin the Street Demon is a nice step on the way but the TQ has a lot more tricks up its sleeve.

    That is interesting. Ive been tuning lots of different carbs the last couple of years and that has now led me to the Thermoquad.

    Thats an idea. Though will look for recommendations here first and in my country before starting with overseas calls.

    Thanks, Glad I asked here first. I was just to tell my buddy to get me a pair of trickflow heads, though maybe I have to consider different heads? I already have the block and full rotating assembly: crank, flat top pistons, rods etc. But yeah, I want this engine to live for a long time, no...
