Help ? tune up

do I need port nozzles ? some say yes and some say no, do I nee a bigger pump ? 548" bbc 14-71 std. helix, 28% over was 24lbs of boost. 48% over was 32 lbs. of boost. open bottom, 110 pump, hat nozzles 4-55's 2-52's, 2-48's and 40's in the back for cooling, ports cyl 2 54 cyl 1 52 cyl 4 50 cyl 3 50 cyl6 48 cyl 5 46 cyl 8 38 cyl 7 42 had 145 main 65 in the high speed, set at 60 lbs. this made for a turd ! ran the same with a 120 in the main and high speed turned around. 2820 lb. car went 8.13 1/4 mile and 5.10 1/8th mile.

 

Go to Spuds website www.fuelinjectionenterprises.com and use his calculator to work on your fuel pressures and boost levels. This should get you in the ball park. I wouldn't even mess with the high speed until you get things sorted out. Leave it turned around

 

More pump would let you run more line pressure and atomize your fuel better, something is off.

We run a 110 with an 8-71@28% on a 572" motor, 14-16psi boost and its been 7.99 in a 3250 lb car.
I think the main is a .092 right now with (8) .039 hats and (8) .026-.028 ports, lots of pressure.

 

I was just wondering why you have a 38 jet in 1 port and the rest quite a bit larger?

 

And probably the least expensive in the long run.

thank you for the replies as far as having a .038 in #8 that is what it took to finally start burning the cadmium off the plug in that cyl. I spoke with Spud Miller over the phone and it looks like My setup will be going to visit him = most correct answer, thanks Will.
