So I finally get the new terry cable in (and my guess is that will only last me a while as well... 2 90 degree bends to get out of the way of the belts....) And just like it has always been, its got wierd sounds, like its rubbing (metal), or something internal is wrong, or something is loose, or bla bla bla.... So I figure its something wrong but I have no clue what the heck it is, so I leave it in the back of my mind... Today (11:20 pm....) we finally get it on the road... Its got a bunch of instant tq, but the partial throttle (more than 25%) is wrong.... First thing I notice is that the metal sound is present, and now, when on a tad bit of throttle (think normal every day acceleration) it starts to make this wierd sound.. like the engines Really working hard. like two completely different sounds emerge.. the normal sound we've been hearing, rumble rumble... now its, WAAAAAHH keep in mind, this is only a little throttle... like very little... Oh did I mention it feels slow under that throttle? I mean, ya... Its got a little tq.. Given I've probably not hit the secondary's yet though... But it feels like its being restricted... like something is SEVERELY holding it back.
No I (or dad) didnt floor it... It felt like the more throttle I gave it, the worse I did to the engine... Keep in mind, we just rebuilt this engine. Its got a Holley 650.. Facet fuel pump (im sure that doesnt make a difference.. Paul is running the same pump.) Some wierd truck/smog exhaust (w/ cat...), HEI dizzy (new) I mean I do take into account that the engine hasnt been broken in yet (planned to do that today a little....) It appears that nothing is rubbing. The only thing close to rubbing is the shift linkage.. and thats pretty darn close to rubbing, but its not. Our thoughts are jetting and timing... Timing seemed to be ok when we checked it.... Any idea's? I wanted this to be fun... nope.. This project has only sucked so far... 3 stinkin months and no payback... I hate doing this... |

It only makes this noise some of the time... Mainly for changes in throttle or load...
There is no steady cause for it to make the noise.. I'd get you guys some video... BUUUT.. my mom took the video camera with her.... (grrr) I dont think the flywheel is hitting the starter.. But I'll look. Spacer is in the crank aka renegade. 350 .030 over bore (like that matters) with mild/wild camshaft, Performer RPM intake manifold (waiting to be installed....) and headers (waiting to be installed) (heck I have double humper heads in the garage as well... but thats for later (IMG:style_emoticons/default/biggrin.gif) ) The Air fuel ratio was rich when we tried to set the idle.. best we could do was high 13's. I want to do some tests today and see what its at, then go from there. As I said Im sure the timing and Jetting are not right, but I dont think that that would cause the problems Im describing. I'll think about the longer throttle cable.. That could work if I could put it around the outside of the engine bay... (ie really long... lol) |
