Ive been talking with a guy here in Sutherlin Oregon that makes custom turbo kits for just about any aplication. Ive been thinking of adding a small turbo since the 235 is already a fairly low compression motor. I may be crazy to try it but I think half the charm of these old trucks are the column shifters and the old sixes. If it works out without blowing things to pieces ill let everyone know what we used. It seems like we are right in your neck of the woods evilstepdad because im working on my 54 for Graffiti as well!!!!
