Re: 91 Vette Doctors 368 Rebuild
Primary ports are small....33.25 to 33.5
 the secondary ports are ported and the secondaries are in the car....they secondary TB no longer seal as they are ported . Also on set did not open all the way....the linkage no longer had a c clip, they replaced with an acorn nut that bound the 2ndrys up..

Re: 91 Vette Doctors 368 Rebuild

Re: 91 Vette Doctors 368 Rebuild
this is why the original owner started pulling the motor....fear over cam failure:

I had good results with removing mine from the car then letting it set for couple hours filled with brake cleaner. Sloshed around good before draining then repeated. For final flush hooked it up to the solvent tank pump outlet with new solvent let it run until the return was clear. Then blew it out with the shop air hose. I was surprised at the amount of effort it took for just having 20k miles of use and frequent oil changes.
