    Great event been to it numerous times. Always found it strange it was advertised as Saint Louis, but it was in Illinois. One of my favorites events.

    15” limited choices: Cooper Cobra vs Mastercraft Avenger vs BFG Radial T/A vs ?

    You know I’ve never run Mickey Thompson tires. The 10.5w Slick I came close to using, but went with M&H again. A close buddy swears by the Street Mickeys. I’m all about a radial tire and drag radials I like. I’ve had a couple sets now, and they have promise. The M&H were a wormy tire on the...

    15” limited choices: Cooper Cobra vs Mastercraft Avenger vs BFG Radial T/A vs ?

    They’re are known for having a somewhat longer life on the street. I’ve got a couple thousand miles and a couple dozen passes on them. Over half tread left. I should get another couple seasons out of them

    My daughter and I mounted new tires on the wife’s Challenger. We drove it all over the place it seems, this was at Five guys for a burger.

    15” limited choices: Cooper Cobra vs Mastercraft Avenger vs BFG Radial T/A vs ?

    I love my Nitto drag radials. Probably better then the BFG I had before. I need to wrap up my Dart so I can burn them up soon, as they are 3 years old and don’t like them to reach 4-5 years old. But they still look incredible, and would hardly spin after warmed up powering the Challenger to its...

    So far awesome tires. The ride is like nothing I’ve experienced, and they don’t jump around and beat you up like any of the other brands available.

    15” limited choices: Cooper Cobra vs Mastercraft Avenger vs BFG Radial T/A vs ?

    We will see how long the honeymoon last, but there the straightest tracking tires I’ve had on this car, after 16 years of ownership. I’ve had all of the above, and am sick of anyone of those tires above. I used to get a Goodyear Eagle GT years ago on numerous A bodies I’ve had. At the time the...

    Just put Hankook Kynergy ST on the Challenger and am shocked the difference between the less than 3 year old Cooper Cobras I haven’t liked since day one. Car drives better then most late model rides, especially with the Borgeson gearbox, just finished a 80 mile cruise and the ride is night and...

    79 Bob Glidden Small Block Pro Stock

    He got a weight break that I think they took back, and put the weight back on trying to slow him down. I’m betting he had a bigger engine later in the season. Everyone was trying to break the 8.50 barrier I watched him run I think 8.58 off the trailer, he parked it. Won the event at Martin, MI

    A fellow I found on Ebay I needed a wiper motor, as mine was probably gonna be a problem due to the welded on wiper arm, and it stopped wherever it wanted, plus I thought I saw a small crack in the case. His eBay store is sniff-out-parts I believe it’s Tommy you can figure out the rest who’s a...

    Difference in X heads & J heads

    Seems I remember the chambers were a little smaller on every set I’ve saw. could be they’re so old someone has machined on them? I liked starting with the small valve j head, and putting bigger valves in. Fresh seat area, valve sitting up pretty flowing better than some wore out x heads with...

    W2 heads I think they are ready

    It ran 7.40s on the motor and 6.90 on a 100 shot with ported j heads on dot tires, and exhaust. Stockish 340 solid cam 1/8th mile. Didn’t get to many opportunities to run quarter as all the tracks were 1/8 mile where I lived at the time. Drove it to the track

    Thoughts on the 452 heads

    I like the short turn on the 906 a little better. Both good heads though, and if I’m not mistaken the 452 have hardened seats. I may be wrong, but it seems iron heads make more power versus aluminum at the same compression ratio, and flow numbers. I pocket ported my wife’s 440 sixpack heads and...

    Stop in for a drink.

    Pure as the driven snow. I found a couple of the last bottles in a lakeside grocer with a incredible liquor selection in Michigan. I had a feeling I would find some there due to the pandemic affecting tourism. About an hour drive. Took the Challenger.

    Early 360

    It was a cheap way to build a 372-373 I had so much good luck with a .060 over 340 which comes to a 4.100 bore I felt a .070 over 360 at 4.070 was possible after sonic testing it. Did you have any sign of it trying to overheat ever?

    CAM AND MAIN BEARINGS SHOT

    Those bearings are far from shot. Looks like it didn’t have enough oil pressure at some point? After priming oil pump, did you roll the engine over with no plugs, and verify oil pressure? What did you use for an assembly lube? Or did someone else assemble? Double check everything and...

    Six pack response...

    I’ve had a sixpack on my wife’s Challenger for close to 15 years. Bought it new. It’s a near seemless experience, no hesitation really. If it’s stomped from a start, it just boils the tires. Starts nice in the morning, and when hot. Runs on the middle carb when cruising. At the drag strip it...

    W2 heads I think they are ready

    I’ll bet it’ll run 10s in its first outing to the drag strip.

    W2 heads I think they are ready

    The geometry is pretty bad though. The installed height is not quite 2” so the .650-.660 roller will work. If I had a height closer to 1.70 and a cam around .550 wouldn’t need it. Mike from B3 racing did a nice job with that kit. Engine should have a smooth valvetrain at 7-8 thousand rpm once I...

    W2 heads I think they are ready

    Thought I would mock up some ductile iron rockers and check. Even with the iron rockers they are to short. If I put my wife’s 440 Sixpack in the neighbors pos Monte Carlo SG car it would probably run 9.80 He’s been struggling a couple years

    W2 heads I think they are ready

    He didn’t have anything to say except when I mentioned if some Harland Sharp rockers would be a better match? He said no, they are worse as far as geometry goes. Never brought up pushrod length, I just thought 2-3 threads is what you wanted showing. I was wrong. Or I should say Crane is wrong.

    W2 heads I think they are ready

    Yellow rose is correct holes don’t line up. Exhaust is not far off, maybe a .100” Intake is not even close of course, with either pair of shafts, both were new sets, one was w2-w5 and the others I’m not sure, billet shafts I think not even close either.
