    Thank you but are valve seals absolutely necessary ?

    I see there is a little pocket cut on the top of each guide and a deep grove thread inside each guide for lubrication.

    If seals are used these will not get much oil at all.

    Will it smoke a lot if run without seals ?

    Hello everyone,

    The engine is finally done and running.

    A big Thank you to Techinspector1 and every one else who advised on this build. This engine was built exactly as advised in this post by all of you.

    Here's a link to a video of it running https://www.youtube.com/watch?v=7Udld1ss1QY

    Looks like it runs better than that fan you had running to cool the radiator! LOL...

    Great Job!

    I've rebuilt a fair amount of engines, the first start is always the best. Nice job and nice stand. Thanks for sharing!

    Sweet sound - almost got a bit of potato-potato-potato Harley rump to it

    I've also built a few and I still get excited when they fire for the first time.

    Great job! Thanks for sharing.

    Which distributor ?

     



    Hello all,

    I'm reviving this very old thread of mine.

    I built a Chevrolet Mark IV big block 454 engine with the advice and guidance of all of you.

    I have only now, installed it into my restoration project.

    I need to buy a good reliable distributor for it.

    I was thinking of using an original Delco HEI unit.

    I have found one with the details below...

    Delco Remy HEI Distributor 1103246
    661
    1977 Chevy Corvette Camaro 350

    Will this fit my engine ?

    Summit Racing's Delco Remy HEI distributors show that it fits V8's from '55 through 2000. all small blocks and big blocks they made. Someone else (Glenn?) can tell you from experience, but I'd say it'll fit, no problem.

    Just for reference, the blueprinted HEI from Summit is just under $100, plus tax and shipping.

    Thank you. I did look at the various different after market options out there and read up a LOT on different forums.

    A lot of folks agree that the unbranded or generic distributors are all made in China and not reliable.

    The general advice I read was why not use a genuine Delco HEI distributor and install centrifugal weight springs as needed to get the advance suited to your own engine.

    I have an aftermarket big block / small block HEI distributor now and it works but is very badly made. It is a lose sloppy fit in the block.

    Up and down or side to side?
    If side to side find another distributor, it's worn out. If up and down it needs shim(s) and easy to replace or add on. The pin through the gear can be driven out and the shaft can be pulled and cleaned. Add to shim pack as necessary but go too tight, the shaft should spin with ease.
    I'd also carry a spare module as they have a habit of randomly quitting.
    I've rebuilt a few over the years with the latest being the one in my 76 Corvette.

    Sloppy fit in the block.. so the shaft of the distributor is too small for the hole in the block.
    Surely if we use genuine Delco modules, are they not reliable ? Weren't those cars reliable when new ?
    Then what other better more reliable option is there ? stick to points ?

    The end of the shaft fits into and drives the oil pump, it will be a little loose in the block.

    Like all electronic equipment, solid state devices are prone to failure with heat being the biggest culprit followed by over voltage, voltage spike. So carrying a spare is good protection.

    Then what other better more reliable option is there ? stick to points ?
    Solid state is greatly more precise than points, so the answer is no.

    Thank you.. the aftermarket distributor I have is definitely too lose in the block. Without the clamp holding it down, it can shake side to side quite a lot in the block where my old points Delco does not.

    Back to my original question....

    will a Delco HEI out of a 1977 Chevy Corvette / Camaro 350 fit correctly into my Mark IV 454 block ? are the length and diameter and the oil slot near the drive gear in the correct location ?

    I will have to find a melonized gear for it as I'm running a Crane hydraulic roller cam
