Hey all I'm building up a 283 SBC for my daily driven 53 Chevy and am just investigating what kind of cam I should go for. My setup is as follows: Fresh 283 - 30 over 416 heads from 305 sbc Camaro V8 T5 w 0.63 OD 3.55 Diff Quadrajet Torquer 1 manifold HEI distributor 17 lb steel flywheel With this setup I'll be pushing 1900 rpms cruising speed (70mph) on the highway I've heard that RV cams provide good low end torque which would compliment this rpm range, but have heard conflicting opinions regarding their economy. Ideally I don't mind a little less low end torque if I can provide more economy at cruising speeds, provided I can move up the RPM range to pull hard at a loss of MPG when needed. Does this make sense? Or is it just more logical and efficient to have a more torquey low end for this gear set.
