    06 Silverado Buckets in 84 C10

    I can't seem to figure out colors on the computer. Many seats I have looked at ant thought to me gray were actually blue........... I was SURE that these were gray..... Turned out to be TAN !! Bummer....they are only $125.00..........

    Thin Head Gasket and Comprtession Ratio

    For all y'all who crave pics, I offer the following: As you can plainly see, the #1 piston is at TDC and is exactly .028" below the deck. Perfect!

    Could I get in trouble for showing pictures of a totally naked block??

    The machine shop squared everything off the main bearing bores. In essence they will have achieved the same result.

    Picked up the block today. All is good. Twas a good thing to have done, as the banks were a tad out of square and not quite flat. Perfect now from a dimensional standpoint.

    I think if I had left the C/R at 9.25:1 then I WOULD have been disappointed with the performance....

    Near as I can figger my C10 Stepside weighs 'bout 4000# The original 2.73 open diff has been replaced by a 3.73 posi turning 29" tires. My Muncie M20 has a 2.56:1 first gear. I also have the ultimate stall speed device...a clutch! I think I'm good...........

    Thin Head Gasket and Comprtession Ratio

    Thanks, but I dunno. This guy used the same cam and a set of Vortec heads and produced over 400 HP: http://www.superchevy.com/how-to/67838-budget-vortec-head-cam-355-build/ My C/R (10.0:1) will be a bit closer to that of the LT4 (10.4:1) the cam was designed for, and my aluminum heads should...

    Thin Head Gasket and Comprtession Ratio

    As long as the 0.012" cleaned up the decks, I plan on using the Fel Pro 1094 steel shim gaskets. They are .015" thick and coated on both sides in order to achieve a good seal. The heads are new aluminum; new ARP head bolts to be installed with teflon pipe sealant on the threads and the Ultra...

    Thin Head Gasket and Comprtession Ratio

    Once the main parameters are set: bore, stroke,piston, and combustion chamber volume, the variables: deck height and gasket thickness are proportional for quench and C/R.. That is to say, the thinner the quench zone, the higher the C/R, and vice versa. If quench is set to the optimal range, the...

    Unfortunately, I used gasket sealer-the black silicone stuff- and had one heck of a time getting the pan off...the gasket is toast!

    Thin Head Gasket and Comprtession Ratio

    This exercise has taught me a lot, but it comes at a price......1 piece pan gaskets are not cheap, and having the block decked necessitated new cam bearings and tanking the block again. Plus the head gaskets.....but, there was no sure way of knowing that or how much deck machining was going to...

    Thin Head Gasket and Comprtession Ratio

    I'm gonna try to have .012 removed from the deck and use .015" shim gaskets. If the decks do not clean up to the required 30Ra surface finish at .012", then I can go to .022" and use the Fel-Pro 1042-026 which is .026" thick. Those are more expensive but will work with surface finishes of 60Ra...

    Thin Head Gasket and Comprtession Ratio

    The short block has been disassembled. (Darn hard to get oil pan off after siliconing the silicine gasket....) If I have .030 shaved from the decks, the resulting .010 piston to deck height will yield about 9.875:1 C/R with the .041 gaskets I have. That will have a quench thickness of .051" How...

    All this may be moot....what C/R can I run with aluminum heads and still use 87 octane gas?

    Piston Variations 350

    I have seen many 350 SBC pistons for sale that list different year ranges of fitment. Q&A for some if these say that pistons for '67 to '90 will not work in '91 to '96 engines or so (approximate.) Considering a 4.00" (or over bore) bore and 3.48" stroke, what design parameters render 350 pistons...

    Thin Head Gasket and Comprtession Ratio

    Things would best be machined square and flat to a dimension based on the tallest piston. I think that .010 is wise, as the proper squish can be achieved with a suitable thickness head gasket. This would require smooth deck. I am not sure mine is currently acceptable. I have found Sealed Power...

    Thin Head Gasket and Comprtession Ratio

    That is an interesting concept. I would have thought that you would want to mock up and measure using the actual piston/rod assemblies that will ultimately be installed in those cylinders-for the very reason you cite. Measure using only one and machine based on that one, the dimensional...

    In the real world, how does one get to a zero piston deck height??

    Thin Head Gasket and Comprtession Ratio

    The pistons which came with my "rebuild kit" are Sealed Power 345 NPS. these have a compression height of 1.54". That contributes to the problem. Going to 1.56" or so would eat up half that depth...
