ok guys... it seems as if when I bolt down the distributor it still doesn't go down far enough to hold it in place...

I should have known better because it did not come close to holding the priming tool in place, but I 'assumed' that the distributor wouldn't have that problem... however, the thing keeps working its self outta time.

well it does have that problems, and I'm gonna have to fab something up that will hold it in place. I'm gonna try to get one out of a just yard that will hopefully game me something I can mess up without having to do it on the only one I got...

Bump the motor over, it'll fall the rest of the way in.

it is all the way in... that is not the problem.

in comparing intakes the distributor sinks a lot lower then it does on the stock one. the small metal peice that hold the distributor in place, and from turning back &amp; forth, is unable to go down far enough to hold the distributor solid.

I think what I am going to do is to take a large washer, cut it in half, and then jb weld it to the bottum of that peice. then when I bolt that down it will keep the distributor from turning. then when I time this thing I can lock down that distributor so it will stay put.

What are you looking for from a junk yard? I have a stock 350 TBI intake sitting in my garage as a spare if you want to buy it off me cheap!!

stock intake won't bolt up to vortec heads... I'm just looking for a spare peice holds the dist. down &amp; in place... that way if I get to creative (known to happen) fixing this one I will have something to fall back on.

Oh, sorry, didn't know you had Vortec heads! It's been a while since I've hung out on this board...

actually it really isn't that big of a deal to fix, and you just gotta be aware of it.

I will post pics when I'm done though. I'm really happy when the way this thing runs, but I'm really disappointed when it isn't timed right. oh, and I only gotta about 100 more miles until this thing is broke in! (which will probably happen today!)

I don't want to mis-lead you, so I would just like to ask, can you give me some more info? What is the problem? The intake is too short, so the base of the distributor isn't touching it? Was the block decked?

this doesn't really have to do with how the distributor fits, the distributor fits nice... but, the part where you bolt the peice that holds the distributor down is higher then the stock one.

so what happens is the distributor is correct, but you got a little metal thing with a bolt that holds the distributor down. when you want to turn the distributor you loosen it, and turn it. then when you are done you tighten it back down so it wont' get out of timing.

well the problem is this, when I try to bolt the distributor down it doesn't hold it down solidly enough. when it is bolted down tight the distributor is still very easy to turn, but not as easily as if it were not bolted down at all.

does any of this make any sense???

when I get the peices out to modify them I will take pictures of this stuff so you guys can get a better picture of what I'm talking about...

should be pretty easy to fix, but my back went out on me today (I got 5 hurniated disks)... It will probably monday when I get this finished up.

Jeff, are there two 90 degree tabs on the hold-down? Could it be upside down? I think I remember someone I know having something like this and that being the problem.

If it is in right, could you bend the tabs down more?

actually that is already my latest thought on this; instead of putting something on the bottum I'm going to put it in a vice so I can bend it a bit more.

I don't think it is going to take a whole lot. with this being my first engine rebuild I didn't realize how tight that should have been. in hind site I should have been more thorough in adjusting that when it was much easier to get to.

just one of the many things I have learned from my first engine rebuild.

If I'm understanding right you could grind (the dist hold down)a bit of the area that bolts to the intake so it would sit lower and hold down the distributor.

oh yea I could, but if you think I'm gonna either a) take out the intake to do it, or b) do that with my record of fires

you are crazy... LOL

I definately think my easiest recourse is to bend that peice a bit. if I screw it up I'll get one off a junked vehicle somewhere.

Jeff,
Are you useing the hold-down that is made out of flat steel with a little offset in the end of it? I think the hold-down that you need if the one made out of steel wire that is bent 90 degrees on the end. There are the two different types and my guess would be the you are using the wrong one.

'85 K5 : Run it til it breaks, then fix it and go again!
 
oh the hold down I am using definately is not made out of wire, or bent 90 degrees on the end.

guess that answered a lot... maybe that stupid thing was off that 77-78 305 also???

I see you got a fun back there too solowookie. I've got a cyst growing inside my spinal column thats pushing on a nerve and causing a disc to hang over. Does strange crap to my left leg cause of that nerve. Doesn't it suck trying to tinker on the truck and you can't bend over some days.

you know it is kinda funny because I could have not more of done an engine rebuild with my back for the last 2 1/2 years then I could have lifted a truck.

I went ahead and started on the rebuild, and as soon as it was over my back went out on me... so I guess while I'm sitting here thinking I had a ton of bad stuff happen during that rebuild I need to remember I actually completely it without any major incidents, and I was blessed enough to do it.
