Hi, This is my first post to the forum. I have been reading the forum for years and got many good tips...
I bought my 59 Camino 2011 and now it is time to rebuild its all original 250hp 348 engine. I belive the engine is now first time open. Everything inside looked factory stock.
Reason for the rebuild is bad blow and smoke what comes out from the road draft tube. Other wise engine worked great.
I already took the block and the crank to the machine chop and got the info that cylinders need to be bored out to 040' oversize.
So now I am about to order rebuild kit from the ebay. There is several kits available to choose form.
I am looking for best the cam/piston combination for the best low rpm torque, good gas milage and smooth idle. My Camino has 700r4 trany and 3.08 rear gear.
Original cam and 9,5 piston combination worked great. The car is a cruiser and the bed is often used so the torque is more important than high rpm power.
Show Car has rebuild kit in ebay with 10,5-1 pistons and Isky 256 cam. I think Isky 256 cam might be good choice for my need but my concern is 10,5 pistons what the kit has.
Manufacturer Isky says in their catalog that max. compression pressure is 9,5-1 for the 256 cam.
What do you think? Would 10,5 pistons and Isky 256 cam work together? Or should I choose kit from other vendor with 9,5 pistons? Or is there some other cam what would work for my rebuild? And 9.5 or 10.5 pistons for this kind of rebuild?
Isky 256 cam specs is 202/202 at 050, 256/256 adv.dur, 112 lb and 492/492 lift at 1,75
