Performance Mods for '68 Olds 350
I've got myself a 68 Cutlass S I picked up a
few months ago and was fortunate enough
to have less than 18k on a rebuilt original
engine (.60 over) & tranny. Only thing is it's
only pushing about 250-255hp as opposed
to the 300-310 I was hoping for when I first
bought it (I only know this by searching the
block numbers). Is there anything
(easy/fairly inexpensive) I can do to get a
little more zip out of it? I'd prefer to not
have to pull the engine as I don't have the
space nor skill/equipment to do so. If I had
my way I would've gotten a 68 442 but I've
got champagne taste with a Miller High
Life wallet. Thanks in advance!!
Not cheaply, and certainetly not without pulling some part of the engine apart. There are timing recurve kits and rejetting the carb to get a few more ponies out of it, but if you want something more serious then you will have go go much deeper, You could start with closed chamber heads, that will raise the compression some, pistons, cam, stroker kit, and so on. Remember power costs, so the more ponies you want the more it will cost.
If it was my car I would leave it alone, or possibly sell it when I found what I wanted.
