Mopar and Crane ended up going with .565 offset on P5153899 and 3900 (retail $636 for either pn). I have a set of 3900s, and also a set of the Hughes 1.5s ($595 retail) and Hughes states they're using .600 offset. If I ever get around to using the heads or any of the other paraphenalia I'll let you know how it works out....but as Brian states, I'd expect to check and correct the pushrod clearance in every case. For now I haven't come close enough to seeing the potential of unported rpm heads, let alone Victors....but it's fun to look at all the pretty parts sitting on the shelf I guess

Would Indy 440-1 rockers work on the victor heads?
Maybe the offset would be correct but I think the standard Mopar rocker arms are actually a little too long for the Victor head. The Victor head is taller than a production head so the pushrods and valves are both longer. Since those two items are at an angle to each other as they get longer the distance between them gets shorter.

I am going to try some Victors this year. I'll post some results in a couple weeks. Here's a pic with Hughes rockers .600 offset. The heads needed a fair amount of pushrod clearancing. .750 offset rockers would really make a lot of pushrod angle. My next set of roller lifters will be offset!

How much higher would a 440 need to rev, to get the most out of the victors, compared to a larger engine.
69 Dart GTS 440 mopar .590 cam, Edelbrock heads, 3200# best et 6.45, 106.78, 10.14, 132.88 mph, 1.47 60ft best 60ft 1.36

I have found mine to run its quickest times when I shift at 6600 rpm and I go thru the trap at 6900 rpm. Thats about 500 rpm higher than when I ran RPM heads.

Well, I just ran my quickest time at PAO last saturday in 100 degree heat. Victor max wedge heads, solid roller, 1.7 t&d rockers, super victor intake, 13:1. 3530 lbs. Launched off the brake at 4800, shifted at 67-6800, crossed stripe at 7000-7100. 9.96 @ 135.17.
Don't know the incrementals because they didn't give out timeslips on the "arm drop" pass, but it seemed to hook pretty good.

Forget the Victors, too much trouble to make them work, little rocker arm choices, what headers to use? Installed height sucks. Push rod clearance issues. The guy I know had them, and they were trouble from the get go. Just get a set of Indy heads..SR's, EZ's 440-1's etc..

yea get the indys and pray you dont have problems. hughes, T&D machine, Harland sharp, all make rocker arms.
I bought one of the first sets of victors and had a couple of problems..edelbrock was great to deal with. find someone to say that about indy? I couldnt.
Pushrod clearancing was the only "special" thing Brian had to do. Plenty of installed height for the .720 lift cam I'm running. My

In my case, I already have a set... and the rockers... and the current headers I have fit them w/o any problems.
However, most of the results that people have posted about were from using them on stroker engines. I'm interested in hearing how they've done on standard 440 combinations like mine, since I haven't done the switch from my current heads, yet.
