RPM Airgap

Hydraulic lifters have a lot of take-up space. since you aren't complaining about lifter pump up, things must be close enough between the min/max of the lifters. It might not be the best idea, but it seems to be working for you.I sure wouldn't lose sleep over it yet.

According to post#24, you are pretty happy with the engine, so why are you fussing with intakes? Just asking..

An easy way I have found to compare pushrod length is to line them up all side by side,on a flat surface, then slide a straight bar up underneath the tips at about 90* to the shafts. Then the other end will tell the story. Sometimes a second straight edge can be helpful.Their average length can be found by measuring between the bars.This method is quick,easy, and allows you to keep them in order.[/QUOTE

I am pretty happy with the engine but I am always looking to make things better and I believe the air gap will be a better intake than the old holly dominator single plane intake.

Now while not knowing the cam size and some other unknown stuff I can't say 100% it will be a better intake but I believe it will.

I am slowly getting things done that will allow me to know all the aspects of my car and engine.

Thanks Don
