****NEWBIE WARNING***I just bought a 68 skylark 350 4bbl I need to know the engine specs what's the compression and what size rear end? I already purchased the biggest cam comp sells 268/218 469 lift 110 what else do I need to peep it up a bit I'm considering headers but the cheapest I can find is $360 any other options
As far as specs go to buicks.net they should have the info.I think Poston sells headers a little cheaper around 300.00.
the 68 4v should be a 'PP' code engine. 280hp / 375 lbft @ 10.25:1 compression. http://www.buicks.net/shop/reference/engine_ident_63_75.html
