My truck is a 76 chevrolet with a 350. It has a race cam in it for some reason. It sound cool but it don't tow worth a **** and my milage is **** also. I figured it out to 6 miles per gallon. I would like to get closer to 15. Is there a cam out there that will increase both low end torque and help my gas mileage? It has a edelbrock dual plane intake, quadrajet carb, headers. Not sure on the heads or compression.

Good luck I get 5-6.5 at 65-70 mph with my 1993 ford crew cab dually towing.

8-10 unloaded around town.

dang istock.... i thought our new dodge we had last year was bad, 11 in town and 8 with the car on the trailer...
when we picked up my chassis over the winter, me and a friend took his new 2004 silverado with the 5.7 in it, we got 16 with the trailer, and 15 with the car on the trailer... not bad, pulled great too

first of all extreme, an 04 chevy would be a 5.3 or a 6.0. they quit putting 5.7 in trucks in 1999.yes gould a smaller cam will perform better and get better milage. i would look into one of comp cams extreme cams. i dont know about 15 mpg though. it can be done but the whole motor would need to built around fuel milage. plus a well tuned carb.

i have a 2000 z71 with a 5.3(327 cid). it pulls excellent and gets bout 17 mpg in town.
not quite as good as a diesel but about 5 grand cheaper in price.

I pull my car with my 2002 Silverado with a 4.8, has plenty of power to pull my 3500lb+ car, 1500lb trailer, and the bed full of tires and tools.

I put a comp cams xtreme 4x4 cam in my bread truck I haul with. I put on a set of vortec heads so I had to go with the small one, I think it has .432"/.453" lift but it makes lots of low end power. I have no idea what it gets for mileage hauling the trailer but it pulls my 30' tag trailer pretty darn good. I'm pretty sure its the fastest Grumman east of the Mississippi.

just curious, with the vortec heads (and flat tops) can you still run 87 octane?

Thats what it is... the 5.3
we've been using a ford powerstroke diesel lately, and it has no problem pulling...
