Subject: Re: The 421 is alive!! by 88BlackZ51 on 2011/8/20 1:09:43 Update: Car pulls really well and most important is very smooth hence the top notch machining. I only have about 450 miles on the 421, but its fair to say that the rings are seated nicely. I had a bit of a rough start up tune but after TPI421Vette flew in for 5 days to help me out we smoothed out hat tune. I haven't had the car down the 1320 because I still have the 4 plus 3 in the car and the 3.07's, but I will attend the track when the ZF and 3.45's are installed and see where it sits in the 11's (all depends on me). I will be putting the car on the dynojet next month but I will say that it pulls harder then Fords bigdog 2011 GT500. Hope all is well with the Guru crew. I will post the newer start up and idle video soon. The idle has certainly smoothed out and I am pleasantly suprised how good on fuel the car is but I think the small heads help out with that. Later. |
