    318 gurus/historians

    I also had one of the motors out of a cop car, 318; 360 heads and thermoquad, for the life of me can’t remember what color it was, it’s black now but that may be what I painted it.

    360 sb. 2bbl iron intake or 4bbl iron intake with 4bbl to 2bbl flat plate adapter, which flows the best? thank you for your time. RR

    Thinking taller was better (8022), only had 1 2176 but never had a use for it at the time.

    360 sb. 2bbl iron intake or 4bbl iron intake with 4bbl to 2bbl flat plate adapter, which flows the best? thank you for your time. RR

    I always ran the 8022 because of the height, but the last few I got (5-7 years ago) the ports were terrible for consistency, makes me think I should have tried the 2176. All water under the bridge now,thanks much! Imca won’t let you grind anything, supposedly.

    Disowning Family Members

    I guess their true colors were shown, think you’re doing everything right and still get in a pickle. You definitely got a reason to be pissed! Been in on afew inheritance deals that we had concerns about and it all turned out ok, but you never know. I would imagine your folks are rolling in...

    Disowning Family Members

    Sorry to hear this, money does funny things. Your folks are the ones who should have written their will differently but probably this was accepted as plenty good when they had it drawn up. If you have any net worth it is really a chore to keep up with ever changing tax laws that can really...

    Pop pop on exhaust side

    When I was racing I loved msd box’s and power glides. Darn near any night at any track someone in my class popped a power glide or was walking thru the pits with a msd box in there hand, no finish, no points. I do know the newer glides are pretty much bulletproof, not sure about msd box’s. They...

    Stock Market

    How are unemployment rates figured? There are a lot of working age people around here doing nothing. Disabled deadbeats that can do anything I can enjoyment wise, but are on Medicaid and living good, a real burr in my ***. Guess my folks raised me wrong.

    Lifter preload...more or less?

    In the long run I ran Hughes adjustable pushrods on the rest of my motors, they are kind of a stinker to set also.

    Lifter preload...more or less?

    If you are shimming the shaft with .125” worth of shims you are moving the rocker up roughly that far, so, the pushrod side grows roughly that much as does the valve side. I did stock magnum rockers on a sft cam with regular pushrods and used arbor shims to set valve lash under the pedestal, a...

    Steve Dulcich on building a budget 318

    I haven’t built a street motor in 45 years, I’ve had some good 318 and 360’s and some dogs of both also. In my early years I built some real dogs putting a bigger cam and such on a stock shortblock, you sure don’t forget those ones! Not everyone agrees with ol’ Aj but he is spot on if you want...

    Steve Dulcich on building a budget 318

    Maybe oil pan and pickup. Intake, and then the cracked heads, that’s another cluster…. Front end stuff can all be swapped over. Not a real big deal for most people, million posts on this subject.

    Steve Dulcich on building a budget 318

    Bingo! MOST LA motors need bored, the decks are all over the place front to back side to side. MOST magnums never need bored and the decks are even Steven, they are right at 9 to1, LA,s are all over the place usuall quite low for compression. So your LA now needs bored and decked and a set of...

    Can someone explain what this plate is?

    Kit car motors ran plates like that.

    Preferred Coolant Temps

    I never ran a bypass hose, cooler weather I ran a thermostat with a 3/16 hole drilled on the outside edge. Race car I may add, bypass hose was something else to go wrong I plugged everything off.

    Crankcase ventilation with blow through supercharger

    On my race cars I simply welded a 1” stub into the valve cover and put 2-3 foot piece of 1” heater hose on it running down towards the ground. I put it wherever it fit the headers and chassis at the time. Since they were circle track motors they were always left front of the valve cover, pass...

    cam/converter selection

    Many years ago a guy on Moparchat was racing a bmod type car up in north-south Dakota, he popped his good motor and was doing good in points so he put a bone stock 360 in it, it would float the valves at like 5500 so he geared it to run at maybe 5300 or so, this thing you would think wouldn’t...

    cam/converter selection

    I haven’t raced this type of class for 35+ years, but I do know some people currently racing imca in this general class. Most if not all are running a Chevy crate engine with a powerglide in high gear, theyrun a direct drive dummy converter so basically it is direct drive and they are running...

    cam/converter selection

    Something’s not right, 3/8 dirt we always ran 5.83-6.20 final, 3.73 direct wouldn’t get you to 5000. 3.73 in second should get you in the 5.5 final range, 15” rubber I take?

    Hypothetical 360 magnum build

    Some pistons can sit out of the deck on a magnum (no factory ones) kb 107 can be close, not a big issue but if you are running a close chamber head (magnum) you have a little work to do. Might have to taylor your head gaskets to the application.

    Hypothetical 360 magnum build

    Guess I’m missing the boat, thought it was for a 3500 or less rpm Durango, could put some icon 742’s in it if you want and stay with pump gas. Not knowing what pistons you have I am just guessing. Putting a scat light rod and a light piston will save you for balancing but that cost money also...

    SB Road Racing/Nascar/Sprint Car/Reving BUDGET BUILD

    I have built afew circle track magnums, a 400 hp, 6300-6400 rpm 5.9 can be built pratty cheap. Valve springs are a must and the ones I built would bend pushrods at them rpm’s, Hughes has some that work well. Could it be turned more In this type of build? I dont know, I was comfortable with these...

    Hypothetical 360 magnum build

    Yes bob weight is different, that is why the balancer and flex plate need to match the assembly, la to la , mag to mag. Not knowing what exact pistons he has it is a crapshoot, I was assuming this assembly was factory balanced or balanced before assembly.

    Hypothetical 360 magnum build

    Yes you could use those pistons in a magnum, not knowing exactly what they are I guess you would have to measure and weigh them. Magnum has a little shorter deck height, magnum pistons and pin are lighter by quite a bit. May have to juggle head gasket thickness to make it work. Afew post here...

    best racing ign system.

    Speaking of vac advance in circle track, in the 80,s when I ran open motors I ran a vac can dist. I had a mighty vac pump laying next to my seat, if it was tacky, 2 pumps gave me 36 degrees, if the track dryed out I released the vacuum to take roughly 10 degrees of timing out of it to make it...

    crank scraper question

    Not sure that they have a pan that will fit your chassis but Champ pans has a good website that has a few good pictures of there oval track pans. They use a bolt in louvered tray, nice stuff!

    Old Race 340 Teardown

    Not sure when the x block came out, the big rage for us was a t/a block and putting aftermarket 4 bolt caps on them, they had a solid main web.

    Old Race 340 Teardown

    When I first started racing this stuff was just coming out, the kit car engines were the new thing and were really looked up to in circle track racing. I have raced the 355 engines for many years. There were aluminum rods for drag guys and the standard heavy I beam for the circle guys. A set of...
