:lol: Holy crap did I just run across a bas azz deal! My motor problems have been solved. My luck must have turned around! I just picked up a complete rotating assembly with a fully machined and ready to build block. This guy also threw in the heads, injection harness, intake, tb, and maf...

Well, I had asked about lifter noise recently and found the problem last night. She went BOOM. Oil pump failed! ***** Too bad too. She was running so good. Plans have changed now. Gonna build it. Let ya know in a couple of months how it turns out.

I agree to a certain point. Forced induction cars have big fuel upgrades (for instance), no back pressure is needed there. Stock, I agree, especially on these 5.0 motors, won't run right. Here is an interesting link...

Well, like I said, less back pressure = need more fuel You take away back pressure, it causes a lean state. Just like any other mods you do to your car, it will effect the way it runs. Every change you make needs to be compisated somewhere else, if the computer can not do it.

Well, not really that, it just reminded me about a phone call I got last night. Spent an an hour arguing the physics of how an engine operates.

Any gasoline burning motor DOES NOT NEED BACKPRESSURE to operate correctly. No back pressure is the best. You just need to up your fuel to compensate for the increased air flow through the motor if you have less backpressure. Sorry if this is off topic, but this backpressure myth gets on my...

HAHA I would not run a "no muffler" set up. Don't think you would have loss of power, but it would sound terrible. Put an offroad h-pipe and some 18" dynomax race bullits on it. The bullits alone will give you more hp over the flowmasters. With the off-road pipe that combo will be loud and...

Already done that Done it already

New problem. My lifters are dramatically tapping at every start. They pump back up after 15 seconds or so, but this just started happening recently. What should be my next approch?

Well, ARP sells a stainless steel bolt kit for this situation. So, I am thinking that I can just drill the heads of the bolts off and pull everything off, then unscrew the rest of the bolts. Sonnds ok to me. Does it sound too easy to ya'll?

In my opinion, turbo tubo turbo! You can make more power without major modification to the motor. Regardless of what others may think, a custom single turbo setup is about the same price as a s/c setup. I am not a drag racer. When finished, my car will be an everyday to work and back 500 hp stang!

:bang: Well, here is another design flaw (in my opinion). I tried to chage my water pump yesterday. It is the original pump (140k). The bolt shafts are corroded to the water pump housing. They will not come out without breaking. Any tips or suggestions?

245 rubbed my front

ok, cats are comming off, next week. Running 93 octane and I pulled some timing out of it. Still lean. So, I will take care of the cats, then o2, then adjustable feul pressure regulator.

Well, I believe that the AOD comp has a better fuel map, not too sure though

bone stock ,with a K&N. New distributor, new plugs, new filters, clean trottle body, no vaccum leaks, new wires, new blaster coil. Everything else under the hood is original.

Any thoughts yet?
