    CNC Mill Mark Removal in Intake Port

    I appreciate your efforts. A wet flow runner needs help keeping or returning raw fuel to an atomized state. The worse the runner, the more help you need to avoid having raw fuel run down into the port. Total CFM flow being effected by surface finish would be incredibly small if any. Quality of...

    Rear diff oil change/check

    Fill it until the oil just starts to dribble out of the square plug hole. Don’t forget the limited slip additive if it has limited slip.

    The launch is like Thanksgiving dinner, you want to get through it without upsetting anyone. :)

    rear tires unloading

    I would tighten the front shocks extension. Slow it down so it tops out softer/later. If you don’t have adjustable shocks in front, you can lower the ride height. Which makes it travel farther, taking longer. If you can’t, is the car throwing the rear axle down HARD? You might slow that down by...

    Question: What is the Best timing chain setup LA or Magnum

    Been so long,I don’t remember, I think the chain is THE priority when you choose a set. Nice that we can fit a bunch of stroke in the block. Downside is long chain due to cam to crank centerline distance.

    Stroker 340>416 Build Advice

    I’m running low 11’s through a 2.5” full exhaust system. Muffler choice was pretty important, 2/10’s improvement going to a Pypes Racepro’s The headers? I have no idea which would be better. I run manifolds.

    Question: What is the Best timing chain setup LA or Magnum

    Years ago I went through this, decided to go with the tensioner. A couple of years later, I was in the motor again and the tensioner shoe was broken, the flat spring was trying to eat its way through the cover. Only Rollmaster and no tensioner for me from then on. You will get smart people with...

    NHRA BO29 information from 1968

    I definitely defer to anyone who had one, but I’m pretty sure every state would be different on registering one. I have read the motor vehicle standards for 1968 and there is no standard that they don’t meet. There were not that many standards then. The reason given for their not being legal in...

    F.A.S.T at Empire Dragway 5/24/24-5/26/24

    I had a very slim chance against this Hemi Road Runner. It is usually MUCH quicker, but it had a temp hemi in it. I cut an .035 and spun at the hit and had to pedal. to his .08? Which was all he had to do to drive out of my life. :)

    Harmonic balancer tightening (crank bolt) engine in car with 4spd manual transmission

    I was working on some small front wheel drive thing with a stick and had the same thoughts. “How much torque can that little crank take?” Just your mind screwing with you, the crank see’s incredible shock loads, far in excess of the torque rating of the motor.

    Turning torque for engine

    Can you go into the afr graph and and add fuel, just say maybe 1 point. See if that stops the overheat. If it does, pull 1/2 point out. Still no issue? Leave it. The software is looking for a “number” the sensor may be consistent, but not exactly representative of a real number.

    Turning torque for engine

    So, I searched “installed Holley sniper and now the car runs hot” there is a post on For B Bodies Only with someone had that issue. Johnny Mac posted and seemed to know the system well. You might reach out to him. He’s on here. I just read a bit of it, but the system might be trying to adjust...

    Turning torque for engine

    In the other post, there is a diagram of the kit. It shows the pump turning clockwise. Coolant flow, as an example, my motor makes more heat than yours. I run the March underdrive crank pulley and a stock A/C water pump pulley, through a stock 340 radiator. They are pretty close to 1:1. So I...

    Turning torque for engine

    Ok, found your other post and went through it. I saw that you thought you had a spring in the lower hose, the. determine did you didn’t. But I couldn’t find where you said you had put one in. Have you? My suggestion is, divide and conquers. Is it incorrect coolant flow or air flow or abnormal...

    Ailing engine (Updated after teardown)

    I think people worry about the surface finish requirements too much. Especially on a deck surface that is not freshly machined.
