Lead additive
Thinking of going to a lead additive for the gas of my 70' vette with a 350 ci, 370 hp, 11:1 compression ratio engine to help boost the performance. What do think? Which product? From where? Thanks, Paul

Re: Lead additive (1970LT1)
Lead additives DO NOT boost performance. They inhibit knocking/pinging. If your motor is running fine as-is, adding lead or increasing octane rating will do zip. :cheers:

Re: Lead additive (Mike Ward)
:iagree: But even so, since you're running 11:1 compression, you can probably use the octane. Do a google search for TEL or Tetra Ethyl Lead & you'll find plenty of different brands of additives. I doubt there's much difference between them since the TEL is the active ingredient in them all. Here's one to get you started: http://www.kemcooil.com/products.php?cId=4

Jack Podell the Fuel Injection expert has real TEL listed in his ads. My stock 70 LT-1 ran better with a 20-30% mix of leaded Unocal 76 110 octane but, I guess NASCAR went to Sunoco this year. I think Unocal still makes race gas, check your phone book or local engine shops for sources. One last fact, it is illegal to put a lead additve into a street driven vehicle nowadays. I sold the LT-1 because it made me sick to my stomach to drive a 54K mile survivor on the road, in Californina, I thought at any minute a "new citizen" without a drivers license would "blow" a stop sign and hit me (I kinda funny that way, my 72 LT-1 has been repainted but is still a good car, just not totally original, a Vette can only be that once.)
