Thread: !964 Chevelle 283

Tweet

Lets see--in the last 20 years--probably 35-50 of them---the only thing hurting 283 over the 327/350 block is the smaller bore limits valve sizes---however, the smaller main size helps on the crank as the higher horse power engines are now using even smaller bearing sizes---
Rev limits as for missed shifts????????you ain't gonna fix that issue by not using a 283!!! valve springs,etc, light valves, shaft roller rckers, rev kits---same price on all sbc
and as for numbers matching deals----------you ain't a goin to use a 350----------

But on the other hand---just this morning delivered a 4 inch stroke Dart SHP to a guy with a 1957 chev------

Apologize if I over generalized Jerry - We're on the same page. People many times used stock or shimmed springs and stock 1:5 rockers in the '60's to try and save a few bucks (against my better judgement even then!) and rev limiters were for "serious racers" and many of my friends were enlisted men living payday-to-payday.

I do believe that the modern heads and their associated valve train components are superior and a bit more forgiving.

Thanks for the PM----you might want to take a look see at the vortec heads that came out around 96----Scroggin Dickey made up some intake manifolds for them that work very good with a carb---and in todays world I would use a hydraulic roller cam set unless you want the solid lifter cluick.




The original heads don't work well with unleaded gas on the soft iron seats--late heads have induction hardened ex seats
