    Break in problem...

    Today, I fired my 360 up for my first break in. Its a relatively mild build @ .060 over with 9.3 compression, and a Summit street/strip cam. It is in my '66 Barracuda and I am using the 273 stock manifolds (I know I know, headers come later). I ran it around 2200-2400 RPM for only 7 minutes...

    Which fan are you a "fan" of?

    My new radiator won't fit in my '66 Barracuda, that has a 360, .060" over (thinking a tendency to run warm until proven otherwise), in it. The 360 has a viscous clutch fan on it and they stick wayyyyy out there in terms of a 360 in an early A body. I need to do something different. I lack...

    Flexplate install tricks?

    The last bolt only grabs a thread or two. I have tried with all other bolts tightened, and I have tried with them as loose as they can be for me to still spin it. Its almost like the TQ bolt hole is just ever so slightly off. I am looking at trying to tap it, but can't seem to get it started...

    360 Pushrod help...

    Using a pushrod length checker, in my .060" over 360 with J heads that have been milled .008", I measured the pushrod length to be 7.480". That is with .030" preload on the new, non-pumped up Howard's hyraulic lifters, with lifters lubed and sitting on base circle. Can I use the standard...

    Bore size precision...

    What is your experience with bore sizes when you measure them after getting them back from the machinist? If you want .030" over on a 360, will it measure exactly 4.030" or will it be under sized by a couple thousandths? Thanks!

    360 harmonic balancers

    Are these interchangeable? They both came off of running motors. The one on the left came off of a 1977 360. The one on the right looks new and came off of a 1971 360. What's the deal?

    What size of tap?

    What size of tap is needed to tap the oil pan bolt holes, and the cam thrust plate bolt holes on a 360? Thanks

    Is this toast?

    So is this a crack or score mark that didn't come out with the final overbore of .060? Is this toast, along with me?

    What would you do?

    My 1966 Barracuda is painted Sublime color (see avatar). It is not even close to original anymore, after motor, tranny, & rear end swaps. The PO littered the inner fenders with ignition parts and then painted them (inner fenders) and the firewall black. Then they drew some weird designs in...

    360 cam question...

    Car specs: 1966 Barracuda, 360 .030 over, Keith Blacks flat tops, Holley 650 DP, 727 auto, 8 3/4 sure grip, 3.55 gears - intended use is primarily street. I measured my cam lift today with my dial gauge. I got an average of .279" intake and .294" exhaust of dial lift. Using the stock rocker...

    Which valves/springs for my 360?

    I am doing a home port and polish on my 915 1.88 J heads. I am going to go with larger 2.02 intakes and am going to replace the exhaust valves. I am not sure of the cam specs, as these heads are going on a motor that only has 3-4k on a rebuild, but has smog heads. The previous owner told me...
