    I've seen all those videos!

    The cheapo Walmart SuperTech filters are better quality than Fram.

    I have picked a few things since last post:

    Went with the HiPotek .512/.512 cam, 220 and 230 at 0.050

    Got the new springs that match the cam - they are a single with Dampener and they don't need the seats cut.

    I also purchased the Hughes Roller rocker kit - found a used set on ebay with the pushrods. I've got to mock it up for pushrod length.

    Compression had been my issue - static compression is 10.9 to 1 with a 62 CC chamber head and .029 gasket. When dynamic compression is calculated it goes to 10.221 with the cam specs. I wanted to be below 10.5 to 1, so that's nearly perfect.

    Am having he EQ heads ported.

    Need to check few other things but, getting closer.

    By the way - yep, fram filters suck. I looked at the videos, I'm now converted.

    10.2 dcr on pump gas?

    How did you come up with the dcr?

    http://wallaceracing.com/dynamic-cr.php

    Bore in Inches: 4.030
    Stroke in Inches: 3.58
    Rod Length in Inches: 6.123
    Static Compression Ratio: 10.9 (:1)
    Inlet Valve Closes ABDC : 36°
    Boost Pressure in PSI :0
    Target Altitude :5030

    Static compression ratio of 10.9:1.
    Effective stroke is 3.33 inches.
    Your dynamic compression ratio is 10.21:1 .
    Your dynamic cranking pressure is 196.10 PSI.

    Did I miss anything?

    A few things on the 10.2 on pump gas:

    Hyperutectic pistons hold heat = better burn
    I am 5030 elevation
    Didn't knock when previously running

    Thoughts?

    So just an update - motor is back together and in the truck. Had to order header and collector gaskets so should be fired up by the end of the weekend. Will need computer tune before it runs correctly.

    Compression is 10.2 to 1 - used the cometic .051 head gaskets. The pistons come up about .005 out of the block - not the .011 I measured (piston rocked, I measured the high side - they average about .004-.006 out of the hole ont he quench side). Heads were ported, new guides and a few new valves.

    Tried to used the Hughes 1550 roller rockers, but didn't have the correct length pushrods so went with stock for now. Will order the correct pushrods and put the rollers on later.

    Very Very unimpressed with FelPro. Was trying to figure out the head gasket thickness and they gave me the following information:

    All of their head gaskets for the magnum vary in thickness (except the race ones, which are .039 compressed) they gave me the following specs on thickness:
    519SD .048-.058, bore 4.180
    9898TT .047-.057, bore 4.180

    What a joke - how in the hell do your gaskets vary in thickness? I'd say because of crappy attention to detail or lack of interest. Besides the fact that the bore size is WAY too big.

    So went with the .512/.512 220/230 @ .050 cam from HiPoTek. Also installed the new converter (2500-2800 stall). Flyin Ryan will be my next contact after it fires up.
