I will pick it out of the car, and you just have to plug it in your engine bay. I went 11.68 @ 114 with radials on a Fri night. Better timing and carb tune will go low 11's, and it runs great on the street, nice and cool. I wasnt going to pull this out for a few weeks but can if needed. Can get a video of it running and picks e-mailed. I have an ls1 for the 74 which is why I am pulling. I also would go solid roller and make some big power. I have approx $6500 into this,asking $4500 obo. Just listing this on here to get the word out. Will take trades, car related, big turbos, LSX parts, 98-02 camaro trans am. etc Thanks
