Index Racing (Engine Build and Tips/Tricks)

@dusterbing the peace
Engine:
I would like to utilize one of the many 318's I have for this car. (They r collecting dust)
I have kb399 dome pistons on 340 bushed rods
I have 302 heads (For a door stop, yes....on your engine, NO)
I have a comp cams 268 grind flat hydraulic cam (224/230 0.477/0.480 lift) I doubt this will be enough??? (No, it won't be enough)

This engine will not get you there @ 3400 lbs. I run a 10.5 index, and like others have said you need to be able to go under the index even in hot humid weather (for example, my car will go 10.3 in 95 degree humid air).

The other thing you need to look at is what kind of tree they will be using (0.500, 0.400, instant green). If you want to be competitive you need to be able to cut a light. My 10.5 index is instant green...which means I need my car to react as fast as possible. I have also run this same index on a 0.500 tree.....VERY different setup (i.e. I will red light on a 0.500 tree with my instant green setup).
