On my build I have a stock 2005 shortblock I have a stock set of 2009 Eagle heads. I use the eagle injectors and. intake. I got .075 head. Gaskets with proper push rods. All these parts I got off ebay and know nothing about.... completely stock stuff. I am using an HHP phase 3 naturally aspirated camshaft I have an aftermarket 85 mm throttle body and I am using a mega squirt from EFI source professionally tuned. I am fairly certain the valve springs and lifters are s*** during Drag Week I ran 12.11@ hi 112 mph in the quarter mile I was getting about 17 mpg all of this in my 3100 pound and my 1968 Barracuda I have a 373 gear and a 27 inch tall drag radial full exhaust the converter stalls at 3100 rpm I think the lifters and valve springs are holding it back for now it revs really weak. I am still playing with timing and shift rpms I'm really not happy with this performance so far
