Andy, where your clearance checks made with checking springs or the ones your going to run? If with checking springs you can expect .035 to .045 more clearance with the regular springs depending on how stout the valve train is and how much everything deflects.

My jesel rockers have a ball end on the rocker side. The ball end is smaller then the lifter side of the pushrod. Perhaps you may need to change the adjusters to the ones that use the other type of pushrod?

it looks to me like the pushrod cup is for an adjuster screw thats bigger than whats on that rocker arm. the adjuster looks like it probably has a 5/16 ball and, and the pushrod looks like its designed for a 3/8 ball.

I got a set of Jesel pushrods today.... Only problem with them is that they cost $42.75 each or $684 per set!
Is the roller cam you plan on putting in so radical it can't use thick wall 3/8" pushrods?
The last test with the Comp MM305S flat tappet cam was thousands of dollars cheaper. It will be interesting how much more power the Jessel setup and roller cam makes on the dyno.

i know its too late to go back now, but the test i would have liked to see(its easy to want stuff when you're spending someone elses money), would have been a roller cam swap similar to what the MM305 cam was, using the same basic valvetrain you used in that test.....then step up to the big dollar stuff like you have now, to show how much power you're getting for the added expense of the high lift cams, and the associated parts required to run them with any kind of reliability.
in any case.....i'll be interested in hearing the dyno results with the new combo.
is this next test going to have the new oil pan on it right away, or will that be a seperate test?

well, i didnt mean anything that extreme in terms of low buck. more along the lines of what i see the majority of guys running, and similar to what i was running when i had the roller in my old 448.
i thought you already had the Racer Brown rockers on this motor for the previous tests, so what i was thinking was more like just swap the cam/lifters/springs/distributor gear, and use a cam with a similar profile to the MM305, and just see what the roller set up was worth.
then go to the big dollar set-up like what you did.
as for the pan.....no telling what its worth without testing, but dont kid yourself....ive seen pretty substantial gains(15-20hp at higher rpms) by using pans that provide better oil control. ive also seen high doller hi-tech pans not work that well at all.
changing the pan on the dyno isnt all that fun....but its not really that bad either.

Andy, great work. Great documenting, also. My buddy and I had a long phone meeting with Mike @ Primedia today, about working with MM mag and our wires. There was a lot of interest at the Indy show last weekend with out race wires, and there will be dyno tests coming up shortly. Would you be interested in using the wires we sent you for the upcoming dyno pulls ?? If so, do you have everything you need ?? Please let me know, as you seem very resourceful.. .

I got a new set of Smith Bros pushrods today. These don't cost nearly as much as the Jesel pushrods but should work just fine. They are 7/16 x 0.120 wall and the end is tapered down to 3/8 and there is a 9/64 cup end. These are the pushrods I'll run in the motor. The motor is almost back together. I just need to double check pushrod clearance and then install the big mondo valve springs and we're ready to light it off.

Andy, how much will those pushrods end up costing? looks like the did a nice job with them.
