A 1" spacer will increase the length of your intake runners which will promote more low end torque but will lower the rpm at which peak hp is achieved.

Since you don't have a cam your hp will peak somewhat low anyway, so it may work well. But if you ever add a cam you might want to consider a smaller spacer.

You might want to consider switching to mass air. Speed density cars are very picky when it comes to increasing air flow, you may have some surging problems even without the cam, definelty with the cam. A custom chip may be needed to fix driveablity problems. You may also not see the increase in power you expect, due to the computer not compensating for the extra airflow like a mass airflow setup.

I am going to try and tune my speed density set-up by bumping the fuel pressure to compensate for the added air flow.

I have seen people on this board running 11's and 12's with speed density. If I cant run mid 13's with speed density then I will switch to mass air but I will avoid it if possible.

I think that I am going to try the ngk plugs, I also need to find a fan shroud so I can put my flex fan back on, the electric fan that I have now pulls too much of an electrical load load.

I have ford motorsport valve covers to go with the 1.7 roller rockers
