    Line lock help, it's making me crazy!

    Pretty sure it is controlling the car by blocking pressure from the rear. This is why it is inconsistent. The holding force is only what your foot is applying and you aren’t applying it enough. Try and push the button then drive it like it doesn’t have a line lock. Apply all the pedal pressure...

    Tips for the track?

    I have not been to a track that doesn’t require and overflow can. I have run closed end lug nuts forever, but always on a steel wheel. If you have sufficient engagement they might make you pull off a nut to show it. I have a loop, never had someone look for it.

    Any benefit to 10” wheel?

    This is something that I have thought about a bit. As crazy as it sounds, my cars setup really leans towards a radial style. The sidewall of the redline is pretty stiff and a radial car is usually under tired for the power level. I haven’t been able to dynamically test my therory, but I did...

    Any benefit to 10” wheel?

    I’m curious as to why it’s better. Is it because you are actually using the sidewall as tread or the change in sidewall angle might make the sidewall less rigid vertically? It must take a higher tire pressure?

    Hesitation

    When it dies, will it start right up clean or does it misbehave a bit on start up. Start up clean it probably was lean. Misbehaves and it is having to burn the raw fuel off the plugs. I REALLY like running an AFR gauge in a car. When the car has an issue. The gauge will quickly reduce the number...

    Hesitation

    The kick down lever should be all the way back on the transmission when you are at WOT. It shouldn’t hammer the linkage, but should be fully back.

    Tips for the track?

    Pinion snubber was a cheap solution to a problem that is much easier and better solved differently now a days. A snubber is just too violent. Shocks are just so much better at controlling axle movement. You give me a “snubber” that uses an adjustable small shock and I would play around with it...

    Looking for the way of old school

    Definitely had door panels to start at least. I always planned on taking more pictures of it, but not my car or shop. Was very nice getting a chance to see an original one. :)

    Tips for the track?

    Play with tire pressures. Spin the tire in the street, you want an even color all the way across. Dark outer edges? Add 2 lbs. Dark center? Lower 2 lbs. Continue until it is even.

    Tips for the track?

    Unless you have seriously old rear springs, just leave them alone. The front A body spring section is so short, you really need a bunch of power and a sticky tire to get wheel hop. My advice is to avoid the puddles that form in front of the burn out box. Line up a bit offset. Don’t spin the tire...

    Solid Flat Tappet Valve Springs

    I was required to run a “race” tire on drag week. It was the only 14” that would work.

    Solid Flat Tappet Valve Springs

    In competition F70-14 redline lines, last week testing was a 14” M&H DOT Musclecar tire. My limited converter flash, (3500) doesn’t let me use all the M&H tires ability. Which works out just fine for me. More apples to apples, just more repeatable.

    Solid Flat Tappet Valve Springs

    Last weekend it ran a 11.24 at 119 with a 1.60 60’, but was with a M&H DOT race tire, not the required F70-14 redline So it doesn’t count, but the M&H DOT tire doesn’t make the car quicker. Just easier to drive. I believe a high 11 teen is possible with a redline tire. Replacing the radiator...

    Solid Flat Tappet Valve Springs

    List everything you know about the combo. I have mine in a note on the phone. I just copy and paste when asked. I have a “somewhat” similar cam. You have more intake and exhaust flow than I do, but I have more head flow,CI,and compression and mine is like the DEVIL! “Come on, it’s only a couple...

    Appreciate some input on spark plug reading

    In regards to collecting data. I’m currently logging AFR,engine rpm,throttle position, drive shaft rpm and g force for a total investment of $700-$800. Not your Racepak plug and play sensors,but not real hard to do.

    Appreciate some input on spark plug reading

    The most dangerous thing is someone with a little information who makes incorrect assumptions from that information. I regret this already, but answer me one simple question. How does the presence of lead in race fuel not change the appearance of the plug compared to an unleaded pump gas? You...

    Appreciate some input on spark plug reading

    There’ s a bunch of fuzzy thinking here. You believe that the fuel distribution throughout the cylinder at time of ignition is vastly different? “Try a lower octane” octane is burn rate. What is burn rate going to do for AFR. I’m trying man, but I can’t remember anyone saying the color of plugs...

    the coloring will be different pump gas to race gas. The VP blue I run is…..well…. blue. The dye and the lead effect what the plugs look like. C12 is green. The cut plug I posted is more than likely VP blue.

    PTC converters switches hands

    Sorry, was interchanging terms. I don’t care about my stall number really. I wanted flash to 3500 and they speced 5500 flash because they didn’t read the sheet and pretty much everything else in my combo would like 5500 in flash. The 6” tire and my description of the class just says no! :) I’m...

    PTC converters switches hands

    Have two converters by them, very happy with both. I did fill out the spec sheet for the last one sent it in. I got a five word email response that told me they had not read the spec sheet. “8” 5500 stalll,$950 + shipping” Went through CRT to get it and it flashes to exactly 3500 rpm. Which is...

    Appreciate some input on spark plug reading

    Fuel pressure does not mean fuel in the bowl. Don’t think fuel is your problem though. An issue I ran into is the rotor being too high in relation to the cap terminal. So the arc marks were up not out towards the terminal face. It would flutter a bit at higher rpm’s. Very subtle. Filed the...

    Do you have a 4” angle grinder? With a cutoff wheel cut the crimp. Red line and pull the porcelain out. This is what you’ll be left with. Don’t compare yours to this though.

    Yeah, FAST wasn’t there, just looking to run the car. Atwood’s would have come down if it got bumped to Sunday. The weather kept Bill D away. The others are just lame!!!:)

    Then in the “last chance” round, left a bit early. Hard to run a sportsman tree for me. Saw his win light so I just legged it out.

    F.A.S.T. 2024

    Then drove over to Maple Grove and made 6-7 runs. Pretty wet air, and cold, was a bit squirmy. Two competition rounds. Lost in the first round. I dumped at the line until he popped up to my door, but not enough.
