    A street strip setup is a compromise. My 10" 3400 is to tight for my 360. This camera is less than a go pro and works great. https://www.amazon.com/AKASO-EK7000-Sports-Waterproof-Camcorder/dp/B01HGM33HG/?tag=fabo03-20

    The heads are probably the limiting factor if your tune is optimized. I go down one jet size in May and another one down in July when it really gets hot and humid. The higher the humidity the lower amount of oxygen available to burn. My car runs best @12.4 flat fuel curve with the O2 sensor I...

    head gasket

    Those pistons should be above deck and trickflows are closed chamber. Measure the pistons comp height and add .040 for your headgasket thickness.

    I THINK I KILLED THE 340

    It runs 11.70s in my 3250 lb street/strip car. MP used to carry .060 composite to drop compression.

    Leaf spring shackle angle

    put the car on the ground, fill fuel, spare tire etc. take a short drive to settle front and rear suspension. I would shim fwd if my car looked like that after a short test drive.

    my bad, my old trw flat tops are not. My pistons are .022-.025 above deck and I run a .060 thick composite gasket with closed chamber heads for many years.

    swapping 2&8 is a no go, the valve relief orientation of int and exh are not the same.

    new 360 advise needed please.

    If the 904 you have has the low gear set in it the 2.76 or 2.94gear 26" tire works great for a cruiser. I've run fast ramp SFT cams with EDM lifters for years with great longevity. The XE262 hydraulic had 2 lobes and lifters start to go flat in 6 months which is why I won't run a hyd any more...

    Am I Going To Be Happy With This Camshaft?

    I would run a SFT with EDM lifters. I've had great longevity and power with the Lunati Vodoo cams. You will also loose around .020-.025 lift at the valve with the SBM pushrod geometry from a cams listed lift.
