I have no clue what the spring pressures are, but I do plan on putting new springs and retainers on. These springs have about 100 passes on them and have been over 7k about 10 times, but usually gets shifted at 6600-6700. The cam looks fine. NA I don't think this cam would turn much over 6k.
Yes sir, Mopar Magnum HD roller lifters, I bought the last set in the US, slightly bigger shaft harder roller. Whatever preload the have with the thinner Cometic head gaskets and stock pushrods & rockers. Probably around .100". They creak when they bleed down and it takes a few minutes before...
Something does not seem right there. My iron headed 318 Magnum (stock cracked heads) with a Comp 20-746-9 HR cam (.506" lift), Magnum Swap valve springs, HD MP lifters and stock rockers will pull well past 7K under 20 psi of boost on E85 (and 18°of timing). I have an MSD Programmable box and a...
Thank you but it was disappointing, drive down to the track with the trailer on and the track is closed, so same time same plan this Friday (they closed because Saturday and Sunday were going to be wet). At least I was not the only one, I saw a mustang on a trailer heading the other way when I...
That's cool that we have the same combo. I'm not sure I would change the gears, even with the 3.23's I spin just after the launch and I have not launched on the transbrake yet, so that may help some. Driving it on the street (I've put over 200 miles this summer on it) is perfect with the...
Sorry, I do not get on here much. That is so cool, I think that was when they were still running the crate engine before Gary had Dick build it into the solid roller engine. I bought the Duster in September of 2013 just after it came out of hibernation after it had about a third of a retainer...
Fair enough, but I had said that I was going to post some about the magazine history of the car.
I did put the new PTC 9-1/2" 3700 stall converter in. Ready for the racing season to begin!
There’s one before that with Paul Rossi tuning the Duster with a 318 engine in it that was built as the first crate engine. Then later in Hot Rod 2005 when they rebuilt the 360 with a solid roller cam and 13.25:1 compressionand again in 2013 in Mopar Action.
But I’m not going to do any cutting on this one. Others have cut it up enough. Please remember that this was a magazine car, and I wouldn’t have cut it up like it is. If I could get underneath the frame rails I wouldn’t be opposed to cut some on the lower core support as it is badly butchered...
