Started the engine for the first time......Oops!
I just replaced the heads in my 86 Bronco (has a 351W). Because of a cracked valve the #1 cylinder was holding ZERO compression. So I replaced the heads (stock heads with new valve job). I also put a new Edelbrock 650 Carb.
I have been doing this for the past month (i work kinda slow) but today I finnaly fired her up!.....But I messed up.
I forgot to check what position the linkage was in!
The throttle was wide open!
Not knowing this I fired it up, and BOOM it fired but it was ideling WAY too high!! at about 4500-5000 rpm! hmmmm I wonder why
. In a panic I shut it off, (it was running for at a max of 4 seconds probably)
Anyway, I looked at the linkage and found the problem, I just need to adjust the bracket a bit and it should be fine. I took off the linkage and fired it up w/o the throttle and it sounded alright (much better then before) but the carb still needs to be tuned & adjusted, but thats normal. There was a little ticking sound that we think was a lifter because it had been sitting a while and the oil may need to circulate a bit more (I didnt run it very long). There was oil pressure so thats good.
Anyway, do you think I could have ruined anything by running it that high RPM right at the start?
Thanks,

definately not good to do that because oil may not have been circulating enough yet before the high rpm cam along but just once won't hurt. i know idiotic people who rev it to the same rpms for about 5 or 6 seconds right after startup just to hear the mufflers. i guess that is why that el camino and monte carlo both bit the dust shortly after.
