I seriously doubt that it's the fuel pump and it's easy enough to check it first. Put a pressure gauge in line, run it inside the car or tape it to the cowl where you can see it, and take it for a cruise...the fuel pressure should not drop more than 1-2 psig below the 5-6.5 that it was during...

I just got here after reading the notice in your other thread. For me and any others that don't have a few hours to study all posts in this 6 page long saga, please give a quick synopsis of what's going on, including all things you've tried, rejected and had success with. You can also include...

Hopefully the Holley kit comes with the blue float/metering block gaskets. Do not over tighten them for risk of warping the bowls and metering block(s). You probably have a 6.5 power valve installed. Replace it with the same or 8.5 valve for fuel economy. The best way to determine which PV you...

Thank you. That version of the graph doesn't show the peak numbers; peak power is 414 RWHP @ 6564 RPM, so about 485 or so at the crank. It uses a solid cam with a "rev kit", and modern style (low I.M.) valve springs. I'm also using 1. :1 rockers all around. The trans is a wide ratio 5 speed...

The rev limiter is set to 7750 RPM.

Does that include a 475 horsepower 327, like mine? Did you read my post #20?

As opposed to a holly, which I have in my yard.:D Quick Fuel is a Holley clone, but much finer craftsmanship. Made and assembled in Bowling Green, KY, with EXCELLENT customer support. World of difference between a Holley and a QF. Besides the inferior quality of the product, Holley customer...

I have a Quick Fuel 750 dual inlet race carb on my 327. Doesn't have a choke horn. One pump cold and the engine starts and runs immediately with a turn of the key (say, 1/4 of one crank), with some feathering of the throttle for the first 20 seconds until things warm a tad. Plugs run perfect...

Why would a double pumper run rich on the street? Is the secondary accel pump discharged like a fuel injector nozzle even though the secondary butterflies aren't being opened? The Edelbrock Performer is higher than the old GM cast iron intakes, about 1/4" shorter than the Winters aluminum...

Very important that the hone was done using the proper grit stone and the proper crosshatch angle. All you can do now is to remove the pistons and check your end gaps again as well as verifying that they are installed (top and second) in the right grooves. Low tension oil spreaders will cause...

Correct, as usual. I have successfully sealed those with clear 2 part epoxy cement. Almost undetectable, but wouldn't amount to more than a "dot" on a judging sheet (depending on the judge, 2-3 "dots" equals a point).

Truer words never spoken: "Install an MSD blaster and coil and the car will run on split pea soup..... " Which coil did you order? If you have a Pertronix II, it's designed to be mated to a 40 KV coil. Pertronix III with a 45 KV coil. In either case, bypass the ballast resistor so coil sees...

I think I had eggs for breakfast this morning but don't remember whether or not I had breakfast this morning. All those engines using 43's are BBC's. I said that there were no SBC's that used 43's, as far as I know.:)

You still didn't clarify the second, and more disturbing part of the cryptic message! I lost 2 nights' sleep because of it.:boogie Xanax, Sominex, whiskey and Tylenol PM did not produce the desired effect.:D I don't know if any 1950's or 60's SBC Chevies were ever delivered with AC 43 plugs...

Can you tell us what makes you say that?:lou Hint: I don't own a trailer.:)

Cryptic. Please explain?:)

The latter. You're not all wrong.................but almost always wrong.:L Hib must enjoy cleaning and changing spark plugs.

Hib and Mikey are wrong again. Owners' Manual states that: 43 should be used for severe duty and trailer towing and sustained highway use 44 should be used for "all around driving" and were OEM installed upon delivery 45 should be used for sustained stop/go driving R45S would be my choice if...

Lou, My 327 would almost certainly show about 360-365 RWHP if it were tested now, in it's present form with the 45kv coil, Pertronix trigger, and MSD ignition unit. I'd be willing to go out on a limb and say that the original heads will NOT support any more horsepower than that. I ported those...

I don't think that anything was amiss. I had been having excessive problems with fouled plugs, and the additional load placed on the engine by placing it into high gear might have brought on the plug misfire issue. I can only speculate. At the time of those runs, believe it or not, the engine...
