THANKS Erik, Mizlplix, Denny, C9x & Nitrowarrior, Sorry I didn't check this earilier to re-post. It's a Holley #4779 double pumper that was gone through by the Carb Shop in Ontario to 'match' my engine {they didn't tune it on the motor, just built it to match my motor}. I gave the place all the spec's on my motor as per my engine builder. I don't have the paper work from them so I don't have that much info {it got lost somewhere between the engine builder & the car builder}. I do know they cut off the choke horn. The plugs show it running rich {tons of black soot on them} so I thought I'd put in smaller jets. I showed up an hour or so into the dyno tuning of my motor so I'm not sure if the Carb Shop or the dyno operator put the 70/82 jets in. But it didn't put out anymore HP or TQ with the 71/83 jets than it did with the 70/82's so I thought I'd go back to the 70/82's.
My dyno sheet has Zero's under the A/F ratio :(. But it does show FHp Hp, ME%, FB 1b/fr, BSFC 1b/Hphr, CAT & Wat. Will any of these figures help??? Oh Eric, what does EGT's mean??? Mizlplix & Denny, I'll get a vacuum gauge & check the vacuum but is there a way I can measure what power jet I have in there now??? I'll look up in my Holley book r/e where is the power jet! THANKS All, Bill
