Hi, I'm in need of a little help on a carb selection. I'm in the process of stroking my 390 to a 445 (Barry's kit at survival motorsports) 9:8:1. I have the RPM heads and intake with a comp roller cam set up (270/276 - 218-224 @.50) I know the cam is on the smaller side, but this is 95% just a weekend cruiser and this cam also offers torque down low. I also have the sanderson shorty headers (only ones that fit in a 56 f100).

I currently have a Eddy thunder series 650, but I got this before I decided to stroke it. Intially I was just doing the cam and RPM intake and headers, got it back running and I needed more power.

So now I'm looking at the Holley Street Avenger 770 and think this should be a better fit for the new build. Anyone have a similar set up and have any advice on what I should run. I will be putting this on the dyno in about a month or so (depending on when the stroker kit arrives). So I will run the Eddy 650 just to see, but I'm sure that will be too small and want to have the bigger option there to get it tuned perfect on the dyno.

FYI: this set up will get me in the ballpark of about 450 HP and 500 TQ. I base this off of Barry like builds that he has dyno'ed.

Thanks

 

I'm running the street avenger 770 electric choke on my 69 428 cj, straight out of the box, and it's been great. Should be fine for you.
