    Hey there everyone, been a while since I have had much trouble on the mustang. But here I am today asking for suggestions or guidance. I have a stock 65 289 with a 4v manifold on it (original 2v car). I was running a far too large Holley carb on the car and had no real issues with it on the...

    I just connected the vacuum line from the ported connection on my holley 600 cfm carb to the vacuum advance on the distributor. after driving it around I noticed a huge difference accelerating was much smoother and it had more power however, after driving for about 15 minutes and stop at a red...

    I have a 66 mustang with a 289 block, but the previous owner said it’s a 302. When I go to time the engine yawing cylinder number 1 I can’t see any timing marks, but when I switch to cylinder number 5, I see the scale and am able to set it to 10-12 degrees. Seems to run fine. Anyone know what’s...

    Back here again...I just received my freshly rebuilt engine and was getting ready for its first start. I set the firing order.... and by my mistake to a 302H.O. not regular 302. When trying to start it for about 30 minutes, obviously it wasn't going to start. Did I damage anything up in the...

    I’ll try and sum this up as short as possible. Car has a 1970 302, we recently put a lunati cam, new pushrods, lifters and roller rockers. It’s also got a Mallory unlite wired up to an MSD box so no vacuum advance. Distributor is dropped in, placed at 10 degrees BTDC, rotor on #1 and it...

    Hi all, So as the title dictates, my 289 seems to bog when I put it into gear. Starts and idles fine, but as soon as I go into first gear, the car dies and feels like it's low in power. I can rev it fine and don't hear anything horrible when I rev it stationary. I don't believe there was...

    I just received a rebuilt / curved distributor after supplying my vehicle specs to a vendor. I have a stock 390 2 barrel in my 68 Cougar, but may put a 4 barrel on this summer. Purchased to have on hand if I did swap in a 4 barrel since I had to pull intake anyways. I am curious what others...
