Build it to Last, build it to kick some arse!
A 350 Chevrolet is the most economical & returns the best HP per $ of any V8 engine out there, Hands Down.
Expecting to make anything more than 400HP from a 350 usually requires a stroker crank (3.75 Scat) & throwing some mild drivibility away.
Cams over the 270 duration range for 3.75 stroke
Cams over the 260 duration range for 3.48 stroke
Cams over the 250 duration range for 3.25 stroke
Cams over the 240 duration range for 3.00 stroke
Adding more duration than this will definately add Horsepower but at the expense of Low speed torque, Idle quality, & Engine Fuel Consumption.
Be careful with cam selection as this will have the most dramatic effect on Streetability...
If this engine is intended for street duty & any idle quality is intended a
FULLY DEVIDED plenum intake manifold needs to be utilized.
Factory stock Quadrajet intake manifolds are perfectly suitable for practically all High Perf engine builds.
Mild porting work on the valve pockets,
removal of all casting bumps & flaws in the intake, heads & exhaust manifolds,
Oil passage & oil pump porting, Utilizing stock volume oil pumps,
High Ratio rocker arms 1.6 and above,
David Vizard "How to Build Horsepower" on a Budget Vol 4 ,
combined with
David Vizard's "How to Rebuld your Small Block Chevy" are excellent reads for the novice builder.
Good Luck ! :welcome:
