The wagon would be AWESOME on Drag Week...

With the space of the wagon, and a roof rack, you wouldn't need a trailer.

Hey, you guys need to stop stealing my idea!  Larry isn't the only one who has a cool wagon. 8)

That wagon is almost as cool as Larry's LOL!

I'm working off memory here, but if you milled off the stock stands, could you or someone create a pair of one piece billet steel stands that would offset the rocker shaft to allow for more ratio? That would entail custom rockers as well of course. At that point the shfts could be plumbed for pressurized oil fed to the rockers through oil ports in the rocker bushings and on to the follower tip roller and the roller at the spring. The same oil could also spray on the springs. I agree with others here that bushings are the way to go. I have five seasons now on the Isky .904 roller lifters with no issues, two,of those with the 1.85:1 rockers.

That is in essence what I have on the 598" with current T&D bushed 1.85 rockers which net out at .900 lift. I need to go to a 60mm cam to avoid ever worse rocker ratios. The stainless rockers provide pressurized oil to the bushing, the roller tip and the two spring oilers. Since going to those valve spring life has improved dramatically.

Good to see you here again, Bill.  Your idea is basically workable, and in fact I have a design that uses the stock rocker shaft stands on the heads, plus a smaller diameter shaft and a bushing with an offset hole in it, to move the rocker shafts closer to the cam.  The rub has been the rocker arms themselves; as you pointed out a new rocker is required.  I got going on that quite some time ago but that project has languished, I'm afraid.  One reason is that with the pistons I have there isn't a lot of room for more lift, so the higher ratio is of limited value.

I am working on an SOHC rocker with bushings instead of needles, in the stock ratio, and hope to be running that this year...

So Jay, was it the needle bearings on past SOHC's that caused you so many issues? It would seem self-explanatory as you go to a plain bushing but.....

Yep, always those needle bearings.  With the Dove rockers, the ID of the roller wheel as tapered and the pins weren't round, so they would only last for a few hundred miles.  With the Rocker Arm Specialist rockers, the needles were smaller in diameter and caged, so they were fewer in number.  They didn't last more than a few hundred miles either.  At least the T&D's have the design right and they last a while, but when they go its the same old thing; needle bearing shards everywhere in the engine, causing lots of damage.

And that is why I got out of the needle bearing business as soon as there was a possibly viable solution. Too many expensive rebuilds. Given your recent power level achievements its clear the cylinder heads and manifold are working. I think the main issue, and we share this, is track time to fully develop the combination.

I may have followed you on the conservative rear gear choice also with a 4.11 behind the 1.80 first gear glide. (sorry C2;) My best 60'ft with the new car has been 1.40 and I'd got there with +4200# convertable. Still learning the trans brake and how to adjust the suspension accordingly, its completely different than the AOD/foot brake setup.

My view has been that there is ET in the Drag Radials, but I sat and watched Kurt Johnson, Brad and you get it done with the bias ply's so I may off on that unless we can get to to 60 ft. Scott Clark helped me crutch the launch with the launch timing settings, but as usual we ran out of time and at DW '16 , tranny due to my error.

All of this tells me to spend more time at local events getting more laps and the track set up right. You'll get those additional tenth's with some further engine development, but man, look at how well Scott and Jack Miller did with the Cougar, I have much to learn.
