Turbo questions, help

Thanks.
Lowering compression was one I hadn't thought of.

You'd be lucky to have 8:1 compression on a stock slant. They are notoriously low, just pefect for boost. Only problem is the pistons are cast so you have to be careful with detonation. The pistons are pretty beefy, but still something to watch for.

Only thing Shaker223 did was better valve springs, just stock 340 springs as I recall.

Go to Slantsix.org and search for the guys listed above, Turbo66valiant and Shaker223, both have done exactly what you are asking about.

BTW, I wouldn't recommend a 2 bbl for the street. With a 4 bbl you can run lean enough in the primaries off boost to make the car driveable, and rich enough in the secondaries with boost to live. A 2 bbl needs some external kind of way to enrich the mixure under boost to work. Maybe a 2 bbl nitrous plate with just fuel and a switch to open the solenoid when it sees boost, never seen it done, though.
