Depends : stock cam ? How's the carb ? Headers ? Rear Ratio ? Trans type ? Stock ballpark - 12 mpg. Cam choice is where it will help or kill your wallet . Get a roller cam - hydralic - tell the grinder you want low end torque - how many 6 grand dashes are you in need of - really - . RPM range is better and wider with a roller cam . An eighth mile machine - torque . You could get into the higher teens with that - and an Edlebrock dual plane manifold /carb . Holly has their own tweak custom shop - can set up the carb to match your car specs. That is the way I'm going . You can also go for TBI . Your choice . What engine is in there now ? - brien - On Sat, 18 Aug 2001 23:15:36 -0400 "GremlinAMC" <GremlinAMC@xxxx> writes: > dose anyone know how bad a 401 will suck gas? i'm tempted to put it > in my 1975 gremlin. > thanks to anyone that helps out, > Rich > > > [Non-text portions of this message have been removed] > > > Community email addresses: > Post message: gremlintime@xxxxxxxxxxx > Subscribe: gremlintime-subscribe@xxxxxxxxxxx > Unsubscribe: gremlintime-unsubscribe@xxxxxxxxxxx > List owner: gremlintime-owner@xxxxxxxxxxx > > Shortcut URL to this page: > http://www.onelist.com/community/gremlintime > Gremlintime(Home of the AMC Gremlin on the WWW): > http://www.geocities.com/gremlintime > > Your use of Yahoo!
