Chevrolet

I have a Chevy Nova wagon with a 4 speed and a 194 6 cylinder. I have added headers and dual exhaust. I will be adding a 2bbl soon. Rear gears are 3:36 tires are 14/70s. The car gets driven daily and I want more grunt out of it.
The two cams I'm looking at are Comp Cams's 252H and 260H.
The manufacturer suggests I go with the 260H. My only concern is a large drop in gas mileage. The cam I have now is stock. Granted the valves will be held open for higher and longer times, but for the times I'm driving "normal" will this be an issue? Thanks.

I have a 4.8L in a silverado. I am wondering if I can put parts on it from a 5.3 or a 5.7L. If I buy a C5 intake or a LS1 throttle body, will they fit on my 4.8? I want to make sure before I go buying things.

If not... what will fit on my 4.8 from other engine blocks?

I own a 1891 Caprice and I had a bad misfire under load only I posted 5 questions to try to figure out the problem asking the Chevrolet experts here on this sight what could be wrong with the car.I received many answers ranging from a bad TPS sensor, o2 sensor , MAP sensor, distributer ignition module, cap , rotor, coil, main ECM computer, fuel pump, ignition switch, all wiring harnesses from the collem to the ignition system also the wiring harness for the fuel pump, Mass air flow sensor, and just about all the components that the car has excluding the engine and transmission itself. I replaced it all as I knew the experts that answered my question had years of experience! The cost of all these components exceeded $2300.00 and yet the problem didnt go away in fact, it became much worse! Anyway, yesterday a 16 year old guy from my neighborhood came over to my house and fixed the car with his first try! how did he do this? He replaced the spark plug wires! The cost was $17.55. Thanks

I took my car in to Tunex today, although it seems that all they did was charge me $90 to change my spark plugs, I would like to verify they timed it correctly. I have a timing light (induction) and I have marked the guage to see it. My question is where do I disable the advance (EST bypass) Stupid haynes manual just states I should follow the tag under the hood, and the tag says to put the EST in bypass mode..... How would I do this. I tried disconnecting each (seperately) the plugs on the distributor, but it wouldnt start. It has 2 for the module, and one lower (dont know what that is, but it ran the same without it) Right now, it is idling at about 12 deg. BTDC, but the tag states it should be 0 (TDC)

Im looking into buying a 1986 Tuned Port Injected IROC Camaro and i was told it Had a 350 small block in it. But i checked the Vin number and it said it was a 305. I dnt know if they had the engine changed out or told me a lie, but i was wondering if there is things I can look for to tell the difference.

It seems to be loudest at about 30mph, and vanish when brakes are applied. It gets quieter on accel, but not gone. Any ideas?
