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...

Looking for a rebuilt or rebuildable 6545 Thermoquad for my 440.

Looking for this strip kit for my TQ.

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.

Many thanks. Quite obvious which one that I will choose. :thumbsup:

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...

Thanks, yeah waiting to hear back from John when he has recovered.

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.

I dont have the TF heads, that order was canceled.

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...

Just to complete the driveline, rear tires are 28".

#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.
