This "how much hp am I making" question gets asked all the time, a guess is NOT how much hp you are really making. Anyone can tell you that you "should" make 350-400 hp...doesn't mean chit. Build the best engine combo with the budget you have and be happy with it, if you really want to know spend the $500 and run it on a dyno.

We see guys all the time saying they have 450...550 or so hp and I ask for the dyno sheet......HUH???, what dyno sheet? They equate their build to a "magazine motor" that has been dyno'd and tweaked to the fullest with high dollar parts. Ol' Techinspector can run a dynosim and give you an IDEA but he would need a lot more info than you gave.

Right around 350 HP. The carb is too much, would be happier with something around 700 or 750 cfm at the most. Tech can probably get closer than I can with what I have to work with.

Thanks for the replies guys. i was hoping for somewhere around 350-400 so that seems pretty good. as far as the carb i think it will be fine since it is a quadrajet and just feeds fuel as demanded. not just dumping it into the motor. i had cliff ruggles help with all the parts so it should be in tip-top shape! If anyone wants to run this and needs more numbers i can get them if you ask.
Thanks,
Logan

The Qjet will be more than fine, xlnt choice....but again a guess is just a guess, a lot depends on machine work, clearances and how the engine is put together and tuned.

I do not use the Quad jet in a performance application. I use Holley's that is what I was referencing too. I am not familiar with the Quad jet. Sounds like a fun ride. Be glad when I get mine done.

I dont know if mine will ever be 100% done. Im sure i will constantly be doing something to it. Thanks for the help guys. If someone else would like to run this through some dyno software that would be fantastic.
Thanks,
Logan
