    Default motor question?/

    WEll I just came across a motor for sale and not sure what to do, this retired doctor is selling a 427 bbc, roller motor, eagle rotating assembly, roller rockers, edelbrock dual plane intake, he wants 3,000.00, says he has 6,000.00 in it. The big question i have is he says he had the motor built for his sons 68 camaro, they dropped it in and drove it for a few months and he said he didnt like the extra weight on the front end of the car, then he took it out and put a 383 stroker in it. The guy has money so its no biggy for him to change motors at a drop of a dime. The guy told me that the motor has sat in is garage for the last TEN YEARS!!!!!!! it has about 2,000 miles on it. I dont like the fact that it has been sitting for ten years!!, I havnt seen the motor, but he tells me that it is not an original 427(60's) its a 1987 or so 454 block with eagle rotating assembly and either I beam or H beam rods, he cant remember. I know that if he didnt keep it covered and if he didnt have the spark plugs in it, it could develop rust in the cylinders from moisture, or water getting in , if it ever did sit outside. He told me the cam is a comp roller/ and comp lifter kit not sure what cam specs are. I looked up a gm short block crate 454 and its about 3,700.00 or so depending on where you get it, so I would like to hear what you guys think? he doesnt want to come down in price so im not sure about it.

    Is this just a long block or is it loaded? Alu. heads or cast? What are you wanting to do with it? 3000 seems to be a fair price if it is loaded and about the only thing I would do is replace the valve springs! Some things I would ask is if he knew who built it and if he had any more info on the motor! 427s make good power but, there is no replacement for displacement!


    SOMEONE SAID YOU CAN'T TAKE IT WITH YOU! SO,IM BURNING IT UP ONE GALLON AT A TIME!

    I know the heads are cast iron, but he said they are supposed to be high perf cast heads, not sure of brand name, they could be G.M. heads (781/049) not sure. The guy that built the motor used to have a race shop about 12 years ago, but he is no longer there, he moved out of town, but i heard good stuff about his motors. The big question I have is ,, WHAT IS BETTER 427(SHORTER STROKE) OR 454 (LONGER STROKE) IN A V-DRIVE? ITS JUST A SKI BOAT, BUT I WOULD LIKE TO BE ABLE TO HAUL SOME ASS TO, SHOULD I BE BUILDING FOR TORQUE OR HORSEPOWER? OR IV BEEN TOLD A LITTLE OF BOTH? ITS A LONG BLOCK, IT HAS EVERYTHING EXCEPT I THINK THE CARB, OR IT MIGHT HAVE THE CARB IM NOT SURE? IM GOING TO TRY AND TAKE A LOOK AT IT TODAY.

    IMHO...i would build a 454 ...you can shop around for a block (Gen IV), crank, heads, rods & pistons, manifold (1x4 or 2x4) etc...most everything you will need to build a nice reliable running motor with good power for $3000 or less & know "exactly" what you have! ...just my .02 cents

    I agree myself, only problem is that there are no good machine shops here, I will have to drive out of town just for machine work, I saw the motor today, it looks ok, was wrapped up in plastic, he had duct tape on exhaust ports, that had come off, I looked in the ports and all ex. valves were closed, lifters are all drained of oil , i guess ? I did not take the valve cover off, but I looked inside and it looks very clean, i could see the roller rockers, I think they are comp, full rollers, he said I could take the intake off and the oil pan if i wanted to. I located the machinist who put the motor together and he remembered it, but he wasnt sure which one it was because he built 5 motors for the same guy, he said it did have a eagle rotating assemb. he said it cost about 1500.00 , but he said if it sat this long he would replace the valve springs for sure, he said he would also take it apart and replace the piston rings since the owner has not turned the motor over in ten years, he said the rings are probly bad? not sure if i agree on that? I thought you could just put a little oil in the cylinders, and prime the engine before starting, but the valve spring thing sounds ok to , the owner said he would take 2,700.00 no less.

    Sounds like if you want to roll the dice, it sounds like it's as good a place as any. Better than most in fact.
    For $2700 you may end up with a
    good engine. Can you make a deal for like half down and the other half when you hear it run?

    I don't know about that one? $2,700 for what you want it for is a steal. roller cam, lifters, roller rockers, block, rotataing assembly, heads etc. etc. Buy it and have fun. but thats only my 3 cents

    Thanks for the reply's I think it is a good deal, now one more question, the guy told me he was building this for a blower, I think he has dished pistons and open chamber heads, so low comp motor big time, (I think) but I dont want some high comp motor that I need high oct. gas either, but this may be to low? not sure i think im going to take a chance and buy it, maybe open it up just to see, the guy told me that I can take the oil pan off, intake off and whatever else I wanted to take off before i buy! so thats a good sign, i figure I will spend at least 2,000.00 on the 454 in machine work, and parts , new crank , rods, pistons, cam, it needs everything, all I have is a good block, I have two 396 motors but they to will need machine work, and like I said I will have to take them out of town for that, and thats a long time from now, I still have one bathroom to in my house to fix, its I gutted it, no shower or toilet, ! wife is going to kill me, or divorce me,

    Default My .02...

    First, solid roller lifters DO NOT bleed off. If ALL the exhaust valves are closed someone either backed off the rockers, or he is lying about the roller lifters being solid, which MOST were 15 years ago.... That would save the valve springs, and seal up the engine fairly well.... $2700.?? You NEED to ID the block and heads by casting numbers, and if there is any doubt about the block being a 4 bolt, pull the pan.... Also check to see which Eagle crank it is....The heads of choice were 990s, rec port, 118cc chambers. Some 427s came with oval port heads, but not the high HP versions that I know of.... ID the pistons, cast or forged, (yeah, even people with the big bucks are known to use cast pistons if that is what the machinist had on hand)..
    Question remains, is this a "ready to rock" assembly, or a starting point to build it to your specs???
    As far as the "stroke", I'm a fan of the 3.760 427s, vs the 4.0 454s when it comes to "quick power" in a small, "dry at speed" boat.... Pulling skiers, you MAY very well want the extra torque the 454 produces at "ski" speeds, but you can gear and prop the 427 to perform well at those speeds as well.
    Again, is this a assembled "basket" case, or an engine you're going to install and run???

    On a side note to establish a rough value, I have a mildly built 11:1, 402 4 bolt, oval port heads, forged pistons and an Isky hyd cam/kit that I wouldn't tale a penny less than 5K for. It is in a jet boat, running well after sitting under a bench for 15+ years with just an oil change and GO.....No it's not for sale, and wouldn't fill your needs anyway....

    IMO, if it's a 4 bolt, if it has rec port heads, and forged pistons, along with the roller valvetrain, AND it's not damaged or locked up, it should be a good deal at $2700. BUT, big BUT, plan on having to do some work to get it where you want it from a performance standpoint, especially if the pistons were originally for a blower set up....

    Well, just like all the good deals I run across something happens, The motor is a 4-bolt main, hydr. roller motor, I had him pull the intake and it is a roller cam, and it is a 4-bolt main, the block is a 1989 454 , 4 bolt main with eagle crank, and h-beam rods, forged pistons, anyway we were at 2,700.00 I told him I could get the cash by monday because thats my day off, so it was set, then he just called me and he backed out of the deal, he says he has more cash in the motor than that and now hes just going to save it and eventually put aluminum heads on it!! ohh well thats the story of my life!!! back to square one, now its between rebuilding a 396 that probly needs a crank not sure or go forward with my stock 454 that needs crank, rods, and new pistons? maybe put the 396 crank in the 454? not sure now, and thats if the 454 block is ok, its getting checked right now. Man i really like the idea of having an eagle forged crank!!! and h-beam rods!!!!shit!!!!
