I have Hughes 1.7's on my 511. No clearance issues with 3/8" Manton push rods.

My reasoning for using them was/is:

1) Most Mopar guys told me not to do so.

2) My cam grinder recommended it.

3) Larger base circle cam, etc.

4) Offset lifter / stability load control.

5) I wanted to have room to grow towards .800 lift, which of course everyone also advised against.

This engine lived for lots of NA dyno pulls and 3 soft nitrous pulls that made around 950 hp and 900 ft lbs at shutting it off at 6k RPM. NA the engine made peak around 7100 with a QF 1050-AN 4150 carb/400-2 intake/Hughes CNC MW Victors @ 11.2CR.

I'm almost done with the GF5R install so hopefully the rest of the chassis work will be done by spring so we can wring it out in April or May.

My next 511 will also get 1.7's. The current deal will help decide if we stay with a shaft rocker or go gold chainer and bust out the $1800 Jesel/T&D route. I also notice that Scorpion has a set of 440 -1 shaft rockers out for about $1200 IIRC?


ps my engines all have screen in the valley for extra parts if the engine decides it doesn't need them any more lol.
