The engine wasn't working very hard at that speed. I suspect it had 2.73 or 2.41 gears concidering it was a big block. With 4.11 gears it would be difficult to drive on the highway at all. I had a truck with 4.10 gears and could start out in third gear on a three speed, and it was screaming at 50mph, so I put 33X12.5 tires on the back and could then drive it normally.
I had a 71 chevelle with a 350, headers, 194 heads, mild cam, and street aluminum intake. It got the best mileage between 50 and 60. A small block will work harder in a heavy car than a big block. Yes physics applies, but they apply on paper, and the results will vary according to weather conditions, fuel used, road conditions and altitude. >From: robert luis rabello <[EMAIL PROTECTED]> >Reply-To: biofuel@yahoogroups.com >To: biofuel@yahoogroups.com >Subject: Re: [biofuel] how much do you know >Date: Wed, 18 Jun 2003 21:20:19 -0700 > > > >Brent S wrote: > > > I had a 1975 monte carlo with an LS6 454 engine.
