Does a 360 magnum use the same flex plate as a 318 magnum?

I have run on E85 for about 5 years. People always ask why..I tell them it's the race fuel of the future. At the track you will want to test your fuel if you addd a couple gallons at a time, or just fill your tank so you know the mixture is the same all day. I feel the E85 is less sensative to...

73 Dart 408 magnum, magnum rt heads, hydralic roller, 12.1 comp, 750 vac, E 85, 904 trans, 3500stall, 3.50 gears, 26x8 slicks,....11.86 @112.86, 1.64 60 ft,(spinning tires) shift @5500

roller rockers seem to have a sound of there own...I call it a sewing machine sound.

WOW! where to start, my experiece down a simular road may help a little. CAM..stock springs are pretty weak, any cam you buy will recomend bigger springs. If you want an overdrive automatic I think you want an early A500 it's an overdrive but it is not computerised, they are in the early...

the pushrod thing is a problem that I already encountered. had to enlarge the holes in the heads because the pushrods were hitting. I bought these heads used and the old rocker arms and pushrods were junk because they would hit the side of the head and as the cam lifted higher they would come...

I would like to thank everyone for your input!!!! As it turns out the problem IS the preload. I just set the lifters with almost 2 turns of preload and it is MUCH quieter. Some times you have to stop doing what always worked in the past and read the instructions.

this is so frustrating. I try to set preload, one lifter will collapse and then another will not. Looks like I have to take each one out and take it apart. maybe some are dirty and that is the problem.

heads were machined for the hughes 1111 springs. Just did some checking .080 is two turns of preload...2.75 turns bottoms out lifter.

had block work done buy a small machine shop...I never asked to have lifter bores done so probably not. I have hughes roller rockers, sewing machine sound is ok, that TAP TAP TAP @ 2500 drives me nuts! I think I'm gonna put it back together and when it blows sell it for scrap. The geometry of...

I have a hydralic roller in one of my cars and have had nothing but problems. If I had the $ to do it again it would be solid roller or solid flat tappet.

pulled the intake this morning to see if I had installed lifters wrong and check on lifter bore. lifters are installed correctly and lifter oil hole is not exposed. I also just read the Hughes instructions that recommend .080 to .120 preload on lifters. I spoke with there tech guy when I...

When I did mine I elongated one hole and used a converter from a slant 6. works great.

I have a 408 magnum, 12-1, E-85, .560 lift hydraulic roller, magnum R/T heads, all valve train from hughes. The problem is @ 2500 rpm it sounds like the lifters collapse, @ idle sounds like a sewing machine. I have tried adjusting the valves warm, cold, running, 0 preload, 1/4 preload/ 1/2...

If you want a little cam upgrade from stock I can make you a hell of a deal on the one I took out of my dart / magnum. lift .480 intake, .512 ex, duration 205 in, 210 ex. Not a big rpm cam but monster torque, if you want more info let me know.
