gears give the feeling of ALOT more horsepower - so yeah, they were worth mentioning.

btw crane > msd every time, hands down.

 

Definitely add headers and nice exhause like flowmaster or dynomax - that's probably good for at least 20hp for just a few hundred bucks.

The right heads and cam combination can make a tremendous difference. You said you have a .500 lift cam... That's pretty decent, could stand to go a little more in a 347 if you can fit it, like a .530-.540 that would be classed as a street/strip cam. Do you have any other cam specs ie. duration? What heads are you running? If they're stock, they gotta go...

 

yah there stock lol.... i want to get them but i dont know where i can get them installed cuss idk how...

 

How much $$ are you looking (willing) to spend? This is important factor when selecting parts to make a "package"...
