DYNO disaster ? Help
The Carb Is Fine...NEVER Too Big For A Carburetor..All You Ever Have To Do Is TUNE It For Your Engine.I Have A 984 CFM Carb Shop Carb On My Small Blocks.It Has Been On Everything From A 416 To A 318 Stocker.Also Had It On Several Big Blocks.It Has 50 MM Squirters And 50 CC Pumps...
I Would Set The TOTAL Timing At 34-36 At 3500RPM With The Advance Unhooked And The Line To It And The Carb Plugged.The Intake You Have Is A Problem.The Fuel Is PUDDLING In The Plenum.This Is What Happens On And FLAT Manifold If You Were To Put A 2" Spacer On The Intake You Will Get A Lil More Tq And HP.
Next Set Your CL(Center Line)Of The Cam At 104-106o(It Probably Requires 110-112o).This Is Where Your Tq Will Increase Drastically.
Use a "2"HOTTER Spark Plug.I Use Champion,Bosch,NGK Or Autolite Race Platinum Plugs.The Bosch And The NGK Are "9"'s.
The Torque Converter You Are Using Is Waaaay Too Loose For What You Are Wanting To Do.I Use Basically The Same Converter On All My Engines...I Use A 38-4200 That Is TIGHT!....
Put A 999(2.77 Ratio)Low Gear In The Trans And A 4.10-4.56 Rear Gear.I Bet It'll Run 13.00 12.90's with just these Mods.
I Dont Like That Cam Either.Id Put A .484 or .509 In It.
Just MHO And What I Have Experienced...
