    Custom 454 won’t idle.

    Thanks to all who had suggestions. As it turns out the weiand box that said 8019 on it actually contained a 8018 intake in it. Silly me, I figured I didn’t have to babysit a massive company to make sure they know how to match part numbers to the boxes. At any rate I have a new one on the way and...

    HEI is stand alone. After I swap the plugs I reckon I might switch to MSD or ??

    Thank you for the input. I will change them out tomorrow morning and keep my fingers crossed.

    I think I agree but would it run at all if they were bad?

    Custom 454 won’t idle.

    So today I started with spraying carb cleaner all over the intake where it mounts to the heads as well as the base of the carb and it never revved up. So then I reconfirmed the distributor is pointing primarily between #1&#8(closer to one) on the cap and pointing at No. 1 cylinder in general...

    Based on how black all the plugs were this morning I’d say it’s rich plus the inside of the brand new carb is already black like it’s one of my old used ones.

    Here are my compression results from this morning also I was able to just feather the throttle enough to keep it rough idling around 600-800 rpm and the highest vacuum reading I got was 8. Thoughts??

    I’m going to put a regulator in this morning. Thanks to several of you for the psi tips.

    Custom 454 won’t idle.

    I will do a compression check in the morning as well as try to get a vacuum reading. This carb is brand new however, I have also put a slightly used carb(750) that was too much for another truck about four months ago onto this truck, as well as a 670 Holley that I know worked great on a Ford 351...

    It will slow roll from about 1800-3500 very nicely. But if you try to rap it really quick it’ll backfire through the carb and die.

    Thanks for the tip. I can swap it for a 3-5 pump I have here but would that not let it idle.

    Also I tried backing the idle mixture screws out to 2-1/2 turns for this cam.

    Haven’t swapped the edelbrock out since it’s giving constant pressure.

    Custom 454 won’t idle.

    The info on this cam is reliable and very streetable with the max horsepower. The next size cam I felt would be too touchy.

    Custom 454 won’t idle.

    Ideally the idle at 700 or so would be great. If I turn the distributor, either way clockwise or counter clockwise more than a half inch then the truck will not start at all. When I do have it running by constantly pumping the gas, I have been able to put it into drive and go around the block...

    Haven’t been able to set base timing because I can’t get it to idle under 3000 RPM. Distributor is a Accell HEI unit with vacuum advance. I can throw a vacuum gauge on it but the reading will be at a high rpm.

    Fuel pressure on the gauge is about 5.5 to 5.9. It is a Edelbrock electric pump and I haven’t had issues with them and I’ve been putting them on the bronco restorations for about 15 years now.

    Custom 454 won’t idle.

    Thank you all for such fast responses. First I will respond to b454rat-I do not have a fuel pressure regulator. The factory pump was 45 psi. I know from past experience all the small blocks I have dealt with I use the Edelbrock 3 to 5 psi electric pumps and they were great. This is an a...

    Custom 454 won’t idle.

    Hello Chevy lovers. Let me start by saying over the past 20 years I’ve typically been restoring 1978 and 1979 Ford broncos so I have built many many 351M or 400 motors for these trucks without an issue. This customer came to me with a 98 two-door short bed with a V6 and a quarter million miles...
