Hello out there. Have another question for you all. As I have stated before, I have an 81 vette with a 190hp small block. I would like to inprove the power of the engine, but I am not looking to spend big bucks, then again I am not looking for HUGE POWER. Anyway, here it is. Stock smallblock with 76cc heads and dish pistons comes out to 8.2 CP ratio. Small cam from the factory, about 390 lift and around 190 duration. HAD an electronic q-jet and a electronic advance dist, and a very slow stupid outdated computer.
And to top it of, the rear gears are 2.87...
Anyway, as I said I am on a budget, for 2 reasons, I have other bills, and another, the car isn't worth alot. No sense in dumping alot of cash into something I will never get it out of.But, I do enjoy working on it and don't as it gives me something to do.
So far, I have found a new q-jet and a 650 holley. Have both in my possession. Both are electric choke, and NON computer, as I don't think holley makes a computer controlled carb anyway.
I have an older HEI with a vacume advance, which I can do away with the electronic advance, and computer as well.
Next, I will remove the heads,today. I was considering putting 64cc heads on it, but, once the heads are off I was considering instead just putting a set of dome pistons in it. Pistons are much cheaper, and will boost my compression ratio alot. What do you think? I am aware that head flow ect makes power, but I am not building a race engine, just want it to have about 300hp at the flywheel. The heads I could get are just a set of older iron heads from a friend. I understand the flat tops are the way to go with smaller chambers, but will I get almost the same results with the pistons?? Will I notice any power increase with the higher cp ratio and a cam, say 262dur and 460 lift??
Let me know what you think. Just remember, this is just a toy car that I drive on the street , not a 1/4 mile car..
BASICALLY: If I put a carb, dist, dome pistons and headers and a cam listed above , will I have a noticable increase in power from stock, or am I way off track..
