- 383 Stroker
This engine has had some work done to it, though I am not 100 percent sure what. I do know it was built as a 383 stroker, and I've added a Performer manifold.
Either way, a V8 that large with a 4 barrel and no emissions should likely outperform a smaller stock motor with a 2 barrel. A coworker used to have an '81 3/4 ton Dodge with an LA 318 and a four speed. He'd leave the shop and lay rubber in all four gears. I'd run the truck out on some back highway, and be at 120 MPH. I figured this thing was built, balls to the wall. One day it quit me at 32nd and Main in Joplin. I opened it up and it was bone stock, emissions and all. Just had a little 2 barrel. It quit because the little brush in the distributor connecting the cap and rotor was so old and crappy it disintegrated.
It seems like everyone is installing the 750 on their 383, but I finally saw some numbers and the difference between it and the 600 is really not a great deal. The consensus among most of the people who have installed the 600 is hair trigger response, which sounds good to me. I'm sick of putting my foot in the throttle and being ten seconds away from the other half of my carb working (which is undoubtedly a carburetor issue).
In other news I cleared off the sticker in the engine compartment. Before the rebuild this may have been an EGR engine, which might explain why the carb is acting a little stupid. If there was a tag on this carb, it's gone.
I'll be ordering a couple of parts for this holley, and probably install it in a couple of weeks. We'll see what it does. have some money coming in soon, and I'll likely go through the ignition. I've had very good results with the MSD 6 series. There's also a set of roller rockers for 1.5 ratio and stock springs on the local craigslist for $100. Those socket style rockers do add a lot of friction to the engine.
As to Bronco vs. Blazer, the apparent lack of 292 six cylinders anywhere answers that question. I am a big fan of the inline six.
