Fellas,
I just bought some NOS 265 pistons off ebay, the price was right ($15.00 for 4) GM part number: 3734079. Now my questions are as follows:
1) Do these look like the ones others have used? I mean, are the valve reliefs in the right place, are they big enough? I am planning on having my head ('71 vintage 1.9) redone with 1.72 intakes and 1.5 ex, and "by the book" from rally bob's post on a good street recipe.
2) What is the best way to make sure that this combo will work out before I have my machinest begin hogging on the block?
3)I know that "green smurf" has done this conversion, with not so great results, I want to make sure that I have the right clearance with the valves and the pistons.

anyonw with expieience, please chime in. I have kept track of all my reciepts and plan on a "how to" if this works out. I do not want to deviate from R. bob's post becasue I think that he has completed this conversion many times. The only exception is that these pistons are NOT the custom venolias that he used.

muchas gracias

My machinist pointed that out. He noticed the offset right away, and I belive mine are offset for the driver's side deck. One last question that I did not post was, what kind of cam should I use since my head used HYD lifters. can I use the came techniques grind you recommended in your street combo with a hydraulic grind? Or can I simply get new SOLID lifters and use the cam you recommended in my '71 head? thanks fore the info, where is your paypal account so I can contribute?..........seriously

Thanx for the info on the cam, Bob, can you recomend the HYD cam mentioned, or would you rather wait for the solid lifters and do the split profile cam that you recomended in the first place? This car will be my "friday" car and will not see much milage, but I would like it to keep up with the civics.
scott, dude, i am from ALVIN, I grew up in that area, my dad is a space contracter in that area, as soon as my airforce gig is up (16 years), I plan on moving back out there. I know of a few folks out your direction that have cars if you are looking for parts and such, let me know.

Jared,
The only question I have for you is: did you trash the S-10 before you trashed the motor? Did you make us look good bro?

on a serious note, do you know if your block had been decked previously? Maybe that was why the pistons were sticking out the top by .020? Also, did you try and "mock" everything up prior? i think that I am going to go that route, on the advice of the machinist. Where did you get the fastners? My machinist says ARP might be the only way to go, I'm just looking for the best price. Just got a gasket set for $40, now I need a 2.0 head gasket, bolts and bearings and I should be good to gizzel!
