I finally got this thing together. I'll try the first start on my next days off probably Monday. I'm doing a big block swap in a 68 Camaro. The engine was a stock 71-402/350. Closed chamber heads, had the valves opened to 2.19/1.88. Added a Voodoo Camshaft. 780 Holley and 10.5:1 pistons.
God I hope it starts and runs ok.

Sounds like you shouldn't have any problems -- good luck and keep us posted

I assume the engine was just rebuilt ? I have no idea how experienced you are but a common start up mistake I see people make on new engines is thinking when the timing dots on the timing gears are lined up..as in when you install them that they can then set the dist with the rotor pointing at # 1. It is really when # 6 is firing so they end up being 180 degrees off on their timing. Rotating it around one more time will bring it to # one firing on the timing tab.

There are several threads about what to do prior to initial fire.

First, make sure you're on TDC compression stroke (as Chuck above mentioned). Valves should be in this position:

Another step to make sure the distributor is in the right place (w/ the timing mark at 0 on the comp stroke), put a timing light on the #1 ign wire. Turn the key/ign "on", and swing the dist back and forth. When you find where it lights the gun, move it towards the driver's side of the car about 1/2".

You can also put the timing mark at 8-10* or so (can even go more, not an issue for the initial break-in), find where it lights the gun and set it there. Same thing, different method.

And have fuel to the engine. If new tank and/or lines, pull fuel up to the pump and put some in the carb bowls as well. If all that is good, you should be good to go :thumbsup:

It cranked, ran smooth, got it broken in, I'm ecstatic. :hurray: Its been 25 years since I last rebuilt an engine. I'd forgotten more then I remembered, but thanks to many hours of reading post on this site, and the people who posted so many of the things I ran into, or had questions about my big block engine couldn't have run any better on its first startup. After I listen to it for a couple more weeks then its time to continue on some body work. Mostly minor, but a few things that need attention. Thanks to all of you for helping me on this phase of my restoration.:beers:
