I have a chance to purchase a freshly-built 383 stroker engine to replace my
350 small block
in a '68 Camaro. I would love the extra power, especially in a car that
looks bone stock,
but does anyone have any advice about any drawbacks or problems I might have
adapting this to a '68 Camaro?
With premium gas at over $2 per gallon, I'm also a little worried about gas
If your'e worried about the fuel cost of the larger engine then maybe
you should think about changing the tranny out for a 700R4 or a T-56
when you make the switch. The engine will bolt right in.

I was thinking about going with a manual transmission, after all, that's the
time to do it,
when the engine is out of the car...tell me more about those trannys you
is it better to go with one of those, or a muncie 4 speeed? Thanks for the
I started with an '87 IROC, 305-5speed.
After getting beat by a '91 350 Z28, I upped that IROC to a 400+ hp TPI 383
that was an absolute torque monster. I backed it up with a T-56, Centerforce
Dual Friction clutch and 373 gears.
On the open road between Houston and Austin, it ticked along at about 1750
RPM's at 65-to-70 mph in sixth gear. In your application, imagine the Muncie
4-speed with two overdrives: 5th +/- 0.7:1; and 6th 0.63:1. I also ran P255
BFG's on the back. Perfect for high-speed strafing runs, and you can
actually PASS a gas station!
I could drive from north Houston (Spring) to central Austin (+/- 140 miles)
on a little less than a quarter tank, plus the notorious Camaro "top heavy"
fuel guage that didn't register below 'full' for about 30 miles.
In a nutshell: do the conversion and go to some deeper gears to help your
launches. It is worth the work, and the conversion isn't *that difficult.
There is also tons of conversion kits to make it easier.

I was only pushing 9.7:1 compression, but spent a truckload on my heads. I
could get real stupid, real quick. That engine is now in my youngest
brother's '84 dually Chevy, running around Houston. It'll light up all four
Granted, bigger is always better, and a big block will *always* develop more
power, but they are, obviously, a much larger, heavier package. Well built
strokers are torque monsters, with all the benefits of the 350 package.
Trust me when I say you won't be disappointed. Once you go Stroker, you
never go back....unless someone has an LT5 laying around.

I decided to go with the 383 stroker in this Camaro, so I'm buying the
engine today. I'll drive it for a while,
and either keep it, or if it's just too much power, I should be able to sell
it for more
than it's worth now with a garden variety 350 in it.
I just got my Camaro back from the shop with the 383 installed. I think it
was a 350 block bored out to a 383.
I'm not sure about the rod length. Has a mild cam, aluminum intake,
Edelbrock carb. It would be real interesting
to go to fuel injection, that might be a good winter project. The engine
only has about 50 miles on it, so it has to
be broken in a little, it runs smooth but it's still real tight.
If anyone has any suggestions about maximizing performance with this setup,
let me know- Thanks, Terry
383s aren't made by just boring the block, a longer
stroke crank is installed. If you aren't changing the
internals and it's a pretty mild build all you can really
do is make sure there aren't any restrictions on the
intake or exhaust side of things, set the timing right,
and tune the carb a bit. 383s are good torque motors,
just don't expect to rev the thing to seven grand.
Ya a 383 is a 350 block, cylinders bored to 4.030" with a 3.76" stroke. If
the crank wasn't replaced, you don't have a 383. You can have a number of
different rod lengths. Ther is no reason a 383 balanced and blueprinted with
forged rotating assembly cannot live in the higher rpm range with doubled
Sure, spin that mild cam that stops making power
around 5500 to 7000. It'll do it for awhile, there's
just no reason to do so. It's pointless. More noise,
no more power, and excess wear.
