Re: 81 Olds Cutlass 3.8/350c to 72 Buick 350 & complete rest
Thanks for all the compliments. No i did not port the exhaust. I would like to study and learn how to do.
Maybe I will look at when I return from my business trip
dogshit said:Looks great. I like how the red block, distributor, and wires, tie in together. There is also enough contrast with the clean cast and the black brackets & pulleys add in a nice touch of chrome with the valve covers & intake and whole package looks great. Lots of guys paint everything one color and it rarely looks as good as it could. The distributor being up front is nice. Crane makes a good adjustable vacuum advance put with an advance curve kit and you will be ready to tune it for power.
Did you port out the opening of the exhaust manifold? If you can use 2.5" 2.75" or even 3" out of the exhaust manifold it will not lose as much HP & especially torque to the exhaust system. Even if you use smaller pipe downstream such as the tailpipes. The stock drag racers do this. A simple H pipe about 2' in front of the muffs also saves a few and eliminates any possible drone. You might also consider upgrading to some good salvage yard electric fans to eliminate power loss from the clutch fan. Mark 8 fans are highly regarded as are any mini van fans that have rear air as are some others. Most who do that also upgrade to a newer style alternator as electric fans draw some juice. My GN came with electric fans and I upgraded to dual electric pullers to the cool the 509 down in the Cutlass and it worked great. Did you run a 160 or 180 degree thermostat?
