    Default build thread

    I finally got around to start assembling my 455. So I figured I would start a build thread I hope to have the engine in the Olds by the end of the winter and have the car running by spring to make the 2012 season . I will update this thread as I make progess on the build.

    Some details about the engine are 72 455 from a Delta 88. The block is .30 with speed pro forged pistons 10.1.1.The rotating assembly has been balanced. I am using a Mondello roller cam with the following specs duration 280/274 Lift .523/.512 with lobe seperation of 114. A set of edelbrock heads and roller rockers from Mondello as well. I will be using the fuel injection from my 502. I hope to get 480 -500 horse out of this combo. Some more pics

    I like that tuned port throttle body you made work on that setup. I would be willing to bet that you will be upgrading to a large monoblade throttle body by the time you're done tuning it. That big block olds is gonna want more air. Looks like a nice configuration. Keep up the good work!

    Thanks. I had same setup on my 502 . It is what I had in my garage. When I get tuning and testing I will upgrade the throttle body . Thanks for the heads up

    I took a couple of steps backwards this past week . I started my car up to take it for a ride and noticed the car was missing very badly and popping through the intake. I pulled the valve covers to check my valve adjusts and found this . 2 broken push rods (WTF) These are brand new parts with a half an hour of run time on them. Lucky for me I found the broken parts lying in the heads. I called Mondello where I bought these rods from to try and find out what had happened . They informed me that I was not the first to have a problem and offered me another set of rods. So now I am waiting for 16 pushrods to show in the mail. ( this SUCKS)
