    Hot Air Block

    What's the casting number on the block?

    Spec my cam please! 4.1 N/A build

    The whole idea of a performance NA cam is to lift the valves open higher and longer. It's much different for a turbo engine that has boost pressure to fill the cylinders.

    Spec my cam please! 4.1 N/A build

    You may want to post in Engine Tech for information on the Kenne Bell cams. More people will see it there and someone is bound to have an old Kenne Bell catalog. They are most likely all hydraulic flat tappet NA cams. I thought an X in the Kenne Bell number was a turbo grind but can't remember...

    Blowthrough build repeat.

    I've seen that tapped/plugged hole in the back of the lifter valley on several '82-'85 blocks. Doesn't seem to serve any purpose, so I don't know what the original intention was. Those original non rollerized cam buttons sure could do some damage.

    That prep work is always a thankless job. Sure seems to be a previous GM rebuild. Odd that the engine was assembled with the rods reversed. Mr. Goodwrench must have been having a bad day.

    Main Bearing Fits Loosely in Billet Main Cap

    NHRA has a guidebook that gives specific information on piston design for most engines as reported by the car manufacturer. A little wiggle room here and there but not much. You can use any piston company but in the case of the Buick V6, only Ross and J&E are approved by NHRA to put a stamp on...

    Yeah I know. That block had been sitting in a guy's garage for 20 years. Didn't look that bad, but one spot of rust in a cylinder wouldn't clean up. After this fiasco, I wanted a block done without any drama. Since I already ordered the .040 Ross custom pistons to stock eliminator specs, that's...

    I have a new set of full length Hooker headers for the G body. Also some Hooker 86-87 turbo headers that are mid length. These didn't work very well on turbo cars because of the long pipes but the headers used by themselves without the pipes are perfect for an NA application.

    1 set of forged TRW standard bore flat tops. I also have 1 set of Buick Motorsports forged flat tops .020 over. I think those were made by Diamond. Both sets look virtually identical and have valve reliefs.

    If it is that far off on #2, I would have expected the others to be about the same. It's the only one.

    It all depends on on your budget and goals. I didn't see what car is the engine going in? If you decide to go non computer, I have a few new NA parts like high compression pistons, headers, a non CCC 4.1 carb, Mallory distributor and maybe some more if I dig.

    It's a late '85 block with the 20 bolt oil pan. It was a sweet low mileage NA block. But for some reason it had to be taken to 3.840 before it cleaned up.

    Whatever the cause, there doesn't seem to be an easy fix at this point. Too bad. I had a lot of money in that block. But have already decided to start over and had a NOS block I've been saving machined. No way would I trust it enough to put an expensive forged rotating assembly in it.

    I should have mentioned this is the #2 thrust main bearing. I tried the bearing on the original stock cap and it fits tight. So tight I had a hard time getting it back off without ruining it. I suspect the thrust sides of the billet cap was machined too much by the manufacturer and is making the...
