    shure will, just like the 95mm bore and the 77mm (2.2) cam as a base to build.
    thats where i am starting from.
    crankshaft will be Hardness-treated, en balanced.

    totay i bought a lot of parts, include a enigne block.



    yes its a 1.6 CIH but....

    when i opend the block , i had a little suprize waiting for me




    as far as i can see/tell , the engine has 0 kilometers.
    pistons are Risse/Omega, rods are polised , crankshaft is balanced and hardness treated.
    hmm, i dont thing the guy who sold this was aware of what he got there, i had a litle luck i guess

    I guess that I've got a weird sense of humor.
    I can see a smiley face with a tongue stuck out with the pop-up pistons.

    okey next question

    as i see, i cant use this pistons for my application.
    as i read, i other topics, there are a manny solutions, for the combination
    Rods and pistons, like Venolia and Crowler.
    orherwise, e sset of forged 305 pistons, can do the job?
    who has other idea's about this?

    305 forged pistons and h-beam rods, ore Crowler 2.3 rods
    Venolia is also a option, but a have still problems with filling out the order form

    annyway, i wil stick to the 95mm bore, i think the combination with te 2.2 crank is
    a good one .

    so what piston rod combination is a good one,.

    I have one possible solution I have figured out. I need to find my notes however!

    I found my notes from 2013. Here is an idea I had, but I have not tried it yet. My plan is to build two engines at the same time, one for me and one for a friend.

    I will use a 2.2 CIH block and crankshaft.

    Connecting rods will be 5.5" long (139.7 mm) from Crower, made for a 2.3 Ford engine. The pin ends need to be enlarged from .912" up to .927" for the new pistons. The width of the big end of the rod needs to be narrowed .013" total, to fit the width of the Opel crankshaft. Ford 2.3 connecting rod bearings need to be used, they will have .0004" more clearance. Rod ratio is 1.802:1.

    Pistons will be forged ICON (by Keith Black) for a 305 Chevy V8. Part number is IC835. Compression height is 1.133" (28.7782 mm), piston dish is 10 cc's. Pin diameter is .927".

    They are available in these sizes:
    Standard: 3.736" (94.8944 mm) > 2192 cc's
    + .030": 3.766" (95.6564 mm) > 2227 cc's
    + .040": 3.776" (95.9104 mm) > 2239 cc's
    + .060": 3.796" (96.4184 mm) > 2263 cc's

    The total rod/piston height is .025" shorter, so it will be approximately .030" (.762 mm) below a standard 208 mm deck height.

    I calculated that with a 1.9 head, and with the pistons .030" below deck, the compression ratio will be 8.524:1. Of course this will change with different heads or with zero deck height.

    But I have only done the math, I haven't tried this yet.

    You'll get better throttle response with 10:1 pistons with a low pressure charger.
    I would keep the boost around 6lbs over atmo.
    That way you can add a 300 shot of nitrous into the mix.

    wow thats nice manny thanks BOb.

    The pin ends need to be enlarged from .912" up to .927" for the new pistons, should be no problem there but..

    The width of the big end of the rod needs to be narrowed .013" total, to fit the width of the Opel crankshaft.
    how do i solve that?

    Two possible ways really. Normally I have the connecting rods narrowed on a surface grinder.

    But you could also have the crankshaft rod journals made wider on a crankshaft grinding machine (if you are regrinding the crankshaft).
