350 heads

[Gary Lagacy]

I recently purchased a Olds 350 and turbo 350 from a salvage yard. The motor came out of a 1976 cutlass. I belive it ran, however I planned to tear down and rebuild. Upon tearing down I have found that this engine has been rebuit before( bored .030, rod bearings are .010 and mains are .020 over) Cyclinder walls look excellent. I plan on installing new rings, bearings and a Eldlebrock Performer cam 37112 and possibly a Eldlebrock Performer intake 37111. ( I am trying to achieve about 300 hp)

Upon taking the heads off I noticed that some of cooling ports of the cyclinder block do not line up with heads ( some completely blocked off by headgasket) Is this unusual ?? What other suggestions do anyone have to achive the 300 hp. I am not planning on racing , just want a little more power for the 1988 Cutlass Spreame Classic than the tired 307 offers.

I planned on initially hooking it to the stock 200 4 r until I can get extra$$ to go thru the turbo 350 I bought. How will this combination work out ( i belive the 200 4 hr has the computer controlled lock up torque converter)???

Gary, I don't see why couldn't get 300 hp. The 350 will be a great engine for your car. Maybe think about headers but not a big deal. Are you wanting to stay on the computer?

The issue of the cooling ports vs the heads is not an issue. Don't worry about it a long as its the correct gasket. Just a note, earlier engines use a different head gasket than the later 77-79 units. So you are fine with the 76. When mixing older vs newer blocks and heads, allways use the head gasket for the block year.

If you go off line of the computer, you will need a lock up device for the 200r tranny. You can go cheap and manually use a switch in high gear, if not spring for the controller...about 75 bucks I think. And if no computer, You'll need a non ccc carb and distributer. If you are using the computer, You 'll need to use the ccc carb and distribuer from the 307.
