eh 335s can be pretty peppy...a guy on a few boards i belong to has a 335, stock heads and intake...with an open cutout he made some decent power, very decent torque...and ran a 13.4@98 somethin...1.7 60'...he did it on hoosier QTPs, 2.73 gears, stock converter with a slipping tranny, and pretty stock suspension. not bad at all. his car wasnt tuned yet either.
