Nice numbers on a DD.

 

thanks dude. im going to start putting a gallon of race gas in with each 1/4 or 1/2 tank of 91 i run.

 

ya, thats definately the highest horsepower 3.12 pulley on a stock motor.

congrats!

 

older thread, but this is still on stock injectors? is this the complete vortech kit, fmu , ss box, etc. just with 3.12? and retune? thanks...seems high, and no talk of fuel starvation makes me think i can get away with just a retune with the 3.12 and hold off on injectors til i go with 2.87 down the road

 

I kept my stock injectors until I went with the 2.87 pulley. Some folks have to change due to running out of fuel and then some don't. I was able to get a conservative tune (AFR 10.5 to 11) with the stock injectors. You can give it a shot. A good tuner will listen for detonation and tell you if the 380 cc's are working.
