I run either a Thermoquad or a Mighty Demon, have considered trying to link up to the throttle cable so the carb doesn't matter, or get the Innovate that is supposed to work with Demon carbs and just use it with that one---although mine has vac fittings where that one connects to the primary...

Good deal. I've got no LM2, went piecemeal with a PL-1 Pocket Logger recording from an SSI-4 Plus that's got an MTX-L Plus, tach feed and MAP sensor feeding it. Thinking of adding a TPS, sometimes I'll get a run that's a little faster or slower than expected when the car doesn't follow air...

Dug up this old question, hoping OP solved the issue. I wound up having to be very careful to isolate the tach signal from my car's MSD-6AL box all the way to the potentiometer. I was routing all of the accessory wires through one grommet in the firewall, when I segregated the tach wire and...

Thanks, good luck with your car! That's the original 14" steel wheels and tires are 24" tall. This past year I bought some 15x5" steel wheels and put 205/75/15 Kumho cheapies on them.

Certainly says steel right there on the website, even looks the part, too. I can't go faster than 12.0 in the 1/4 mile, 7.50 in the quarter, during the heat of summer usually not a problem but when it cools off it can get close. My drag car deals with the weight fine, but I can see where it...

In another thread the OP mentioned Bassett rims, 67 R/T Wheel and Tire Help and I've found that Speedway carries those and an aluminum one with 5" bs on 8" rims. Searching... | Speedway Motors, The Racing and Rodding Specialists

Yeah, something we can't really do at home, so a pretty significant one and the key to getting tires to fit. At least it's an option when we can't get the aluminum rims we want from a catalog or the used parts supply chain.

Pretty much a custom job to get them to fit then. Thanks!

This is my car when the Superstock Springs weren't so old, back in 2013, so about 8 or 9 years in. They were supposed to raise the car but it wasn't much over the original 318 spec springs. Maybe I got some pretty flat ones, doesn't help that the battery's a big one and sits behind that right...

Are those steel wheels? I've been looking over rims to put wider slicks under my car and not finding anything with the offset I want. Best is zero, then most run into negative offset.

I don’t know what differences you will see between spring choices when it comes to wheels and tires. I ran a set of super stock springs and hangers for years on my 67 Belvedere and for the past 2 have used xhd from ESPO. Wheels, tires and slicks the same, General 255/60/15 on steel rims from...

I think it's more of an emissions concern than anything else, there are claims for it helping keep plugs and chambers clean. I know I've left my vacuum line disconnected on trips back from the track and have driven around without it for a few weeks, similarly no noticed problems from a driver's...

Thanks Aron, that's the sort of feedback I'm looking for. Eliminating the vacuum advance system may get some or all of that credit, I'm willing to do without it as the car sees less street time and no long trips.

It'd be worth having a cap that doesn't move around on the distributor, I'm looking at just switching back to the factory female style cap terminals and setting the wires up to match. Don't need a surprise loss of .2 on an actual race lap. Have had pretty good luck with the MSD box, 15 years...

I probably shouldn't restrict this to HP, better consistency is a solid performance measurement as well. Not allowed to have a crank trigger on my 440 in the class I race (Sportsman) unless they've changed the rules.

I put a set of Firecore wires on my 440 in place of my old Jacobs blue wires, decided to go with HEI/male tower connectors and bought a customwiresets distributor cap. I'm running an MP distributor, long ago set it up with light springs and welded slots so it only adds 17deg. One day this past...

That's the problem with me, too, I don't write down part numbers like I should! Ain't no knocking out these studs, gotta find someone with a swedge cutter to get 'em out and I'll measure then. Short chance, but hoping someone's done this and recorded the part numbers so I could order them now.

Does anybody have a part number for suitable press-in studs to use on my original 10" front drum-equipped '67 Belvedere? I'm wanting to use Weld wheels up front and require longer lugs. Already run 3" studs on the rear axles, haven't found anything more specific for factory drum hub use than...

I do not have a FB account on the laptop I use for this site and am able to see the links, hopefully it works for others. My purpose with this posting is to show that my car wasn't really raised much if any over its height with the 318 springs the car came to me with at 45k miles (I don't...
