I was thinking of using my spare (that runs good) 350 chev v8. I was going
to buy a cam (advice needed), use the 305 heads on it (advice needed). I
have a awesome running 305 but it don't have the power I expected.. It has a
edelbrock carb, intake and comp cam. I was looking for any advice on what I
should do.. I keep hearing bore the 305 to 335 or 327 ???.. stroker bla bla
Thanx for any help anyone hear can give. thanx
I am using it as a playtoy to burn tires and maybe drag race once and a
while (not 12 seconds or anything, just for fun) Hoping for a 14 second
Don't use the 305 heads on a 350 motor. The valves are smaller which
will hurt more than help. Look up GM fast burn heads and see if you
can get a set of those cheap. Put the cam, (I think it will fit, call
Competition cams for comfirmation), intake, and carbeurator on the 350
as a base application making sure to put the lifters back in the same
spot they came out of and see how it runs. Changing the metering
(rods?) on the carb may be necessary because of the larger
displacement of the engine.

As RSCamaro said don't use the 305 heads. You can't bore the 305 enough
to get much extra displacement and their small bore and resulting small
in the heads, small ports, etc. is what holds them back. You already have an
Edelbrock carb and intake, I'd get their Performer RPM cam IF you plan on
getting your heads reworked or replacing them with a set of fastburns or
similar. You could also try one of the newer grinds like the Lunati Voodoo
cams or Crane Z-cams, but with their higher lift numbers for a given
you'll have to pick conservatively with your stock heads as they won't work
with lift numbers past about .480 without pulling your press-in studs out.
to mention once you go much past that number you start needing to consider
a higher stall speed convertor and lower gears, depending on what you're
putting it in. I don't follow this group much anymore so I don't know what
the specs are on your vehicle.
If you're on a serious budget there's not much more to do without getting
into the cylinder heads, raising your compression, etc.
You could also say screw it and put your intake and carb on the 350,
slide in a Crane #100172 camshaft (with a 106 lobe sep it rumbles like
a massive cam but with 274 duration and .450 lift it pulls good down low),
and sell it to someone else, then buy a GM crate motor. Used, they're
getting cheap enough that it's almost not worth the hassle to rebuild an
older engine for a regular street application. Hell, even new some of them
are a steal...
Just some things to consider... If you do just want to throw a couple parts
on that old 350 to wake it up that Crane cam is a sweet piece and it's cheap
because it's an older grind. Typically it's about $130 for a cam and lifter
and on sale it's more like $100. Whether or not you'll get 14s depends on
several other factors that I can't help you with without knowing your
If you have the cubic dollars, any timeslip is available.
