Got that out of the way... You WILL beat a stock GEN3 LS1 in your T, a GEN3 with exhaust and intake will be door to door at any speed, standing start or roll on... I know from experience from my best mate who has done this to his (manual) VU SS ute...I beat him, he did exhaust and intake and we were door to door, he got edit and I now lose... badly... Edited LS1 will beat a stock T... I've beaten a kid on his L's on a CBR 250RR in my stock T... he couldn't believe I went with him and beat him... I do because I used to have a 4 stroke 250 and they aren't that fast... I can't wait till I 'go' with a decent sports bike in my T... if it matches the face on the kid with the 250 I'll be a happy camper!!! Nice Jack
