Hey everyone, I recently put a brand new 650 double pumper on my car. When the car is fully warmed up it runs great, much better than my 750 vacuum secondary carb i had. But for some reason if i gas it (before it is fully warmed) i have a really bad stumble or misfire in high rpm WOT...

Great, I just need to block the power valve circuit?

No one know?

I have two Holley 3310 carbs with the secondary metering plates. Can i replace the plate of one with the primary metering block off the other, so that i can adjust the jets if needed? I know summit racing has a kit for about $50.00, but times are tough. thanks

That car still needs alot of work and i very seriously question the 430 HP. Nice guy though.....

Are fenderwell headers that close of a fit. I believe the motor was lowered roughly 1/4" on passenger side and shimmed up an 1/8" on drivers side. This is from the schumacher location. Wouldn't i have a little more room as it is a B motor not a RB?

Yes, this car is strictly a street car. I used to have a 69 cuda with a 440, I did install schumacher headers on it, but they are pricey and i had to raise the motor to install, as it had power steering. I can't afford that kind of money and i don't want to much hassle. I was thinking i...

Will take a look later for the casting number. Although, I will say my motor isn't on stock mounts.. It has modified schumacher mounts. Clearance issues.

That's a significant gain. I know you have to cut big holes in your inner fenders, other than that, what else is involved that makes them tuff to do?

They was on the car when I bought it. I almost sure they are not HP manifolds.

I have a 72 Duster with a 400. Mild build, including: 452 heads shaved .060, Weiland dual plane intake, comp cam 224/230 duration 477/480 lift, 750 cfm holley, and i'm running stock type exhaust maninfolds. How much Horsepower should a gain if put some longtube fenderwell headers? Is it worth...

Upon inspection of my spark plugs today i found one not seated properly. It felt tight but you could see it had been blowing. The whole plug and the bottom of the boot were black. The threads must be crossthreaded. Could this be affecting my performance? If so, How?

It has a stock coil.

Have tried that, didn't see anything.

Does everyone think i would be wasting my time with a new coil?
