    Anyone want to take a guess what my 71 would run 1/4 mile at with this motor, th400, 2500 stall, 3:42 rear stock heavy duty suspension, full weight 71 skylark? It was not built for the track but I am curious.

    I input what you had into my Virtual Dyno program. I guessed that you had 2.13/1.85 valves, 202 intake volume (runner + chamber). 3500lb car and 200lb driver. The program gives 454hp@5250rpm and 518trq@3750, darn close to your numbers. It estimates a best 1/4mi of 12.32 @ 109mph. I can re-run if you want me to change some numbers.

    I looking to put on BFGs 275 60 R15's in the rear for some bite and the look. Any thoughts or other suggestions? Just have some cheaper 225 on there now.

    Thanks,

    Well were getting closer with the install.
    I want to see what you guys reccomend for tire rear tire size. I am thinking 275 60 R15 or should I go 275 50 R15? Now with the above mentioned build I will be running a cruise-able 3:23 rear end.
    Maybe I should of poste this question elsewhere but I'll try it hear.

    i would go with the 275/50's (26" tall) with the ratio you have.

    Doesn't matter what tire you use now, it will spin and spin good even with a larger tire. Just get a tire that looks correct but have an extra set of sticky 275 50 15s for the track, it will keep the ratio low for a good launch. Nice combo though, it should grunt with the best of them!

    Congrats on the new power plant!! I'll bet you are smiling like the cheshire cat...

    I have a motor being built at AM&P and I can't wait to replace my all stock, factory 400 (113K miles) with the new bullet. Of course, the numbers matching 400 will be waiting on an engine stand if I ever need to sell her (yeah right).

    Watch your temperature with the added HP!! More HP more TEMP ..simple physics.

    Your reading my mind. I have a new 4 core Radiator for the car and will be ordering a trany cooler. I'm not going with an aluminum radiator since I am hoping the 4 core will be enough
    Any suggestions on nice fair priced trany coolers??
    Thanks,
    Mike

    Any guesses as to what hp will be put to the pavement considering the dyno results? Above all going through a th400 stock drive shaft 3:23 rear.

    Anyone use a custom lighter drive shaft? Worth the expense? any more performance? Maybe over kill but curious.

    Hope to have all done for Englishtown coming up in a few weeks. look forward to meeting some new Buick friends.
