1971 Corvette: big block..454 cid 4 spped car..camshaft will interfere

Customer Question

I am building a hig performance engine for my big block 1971 Corvette. It is a 454 CID 4 spped car and will have approximately 650 HP. Because the camshaft will interfere with the vaccuum producing capabilities of the engine, I will need to install a vaccuum pump on the car. Corvettes of the vintage have many systems driven by vaccumm including wiper doors, headlight covers, power brakes booster etc. I am aware of two kinds of vaccuum pumps available; 1) electric, and belt driven. I "think" I would prefer belt driven. I have been told they are superior to electric. I would like an experts opinion on which unit would perform better, and where to buy both kinds. Thanks.

hello;
   I must admit I am not a street rodder kind of tech, but I do know someone who can probably help you out.   He owns a speed shop, restores corvettes, and is a well known builder of competition race engines in our part of the country.
   Try calling Terras Automotive
              (NNN) NNN-NNNN
               (this may be the # XXXXX their auto sales office, but it is in the same building)
They are located in Bloomsburg, Pennsylvania.
   You want to ask for Lou Terra, the owner.   He is much more knowledgable about racing and custom engine questions than most of the guys he has working the counter. I am sure he has run into this problem in the past, and will be able to recommend a solution for you.

   Hope this is helpful.
