    After 25 years, finally got my 427/435 tri power running�.

    I’ll try and upload the short video into YT and post it up here.
    After a couple of weeks of prep work and figuring out the TI ignition system, the day finally arrived.
    The back story is I purchased my car from a fellow who had the motor rebuilt 25 years ago when he started his body off restoration and then ran out of steam on the project.
    He never ran or broke in the engine. In fact, it’s never had oil in it.
    I sprayed WD40 into the cylinders, made sure the motor was freed up and it turned freely.
    I ran into some problems when priming the oil pump with my drill and primer tool. With the valve covers off, I was not getting oil up into the heads.
    I turned the motor while priming and that did the trick. Oil was flowing!
    Helping me were 2 friends, both very familiar with Chevy BB motors and ex mechanics.

    Looking for opinions and advice. Initially, the motor ran and sounded amazing. As it warmed up, it started running rough (like it was missing)with a slight noise in the area of cylinder #1. Oil pressure was good.
    I shut it down, pulled the valve covers and removed all the plugs.
    Systematically, I checked each cylinders compression and they were at 175psi with the exception of #1. That registered zero.
    I loosened the rocker arms for intake and exhaust slightly and then rechecked #1 compression again and got 180psi.
    I then tightened again to specs and got zero for compression.
    Before I start pulling heads, curious what all of you think.
    My friends helping think it’s a bad lifter.
    BTW, I have a Howard’s Cams Race series hydraulic roller cam with vertical bar roller lifters.

    Any and all opinions welcome.
    thank you,

    Joe

                    Pulled the intake and cylinder #1 both lifters were stuck.
                    I called the Cam father, Ron Iskenderian aka Isky and ordered a whole set of Johnson roller lifters and a new set of pushrods.
                    Installed them, put the intake on and fired her back up. Ran and sounded great!
                    Good news! And thank you for posting what you found.

                      Can you disassemble the stuck lifter to maybe find out how it got "stuck".
