Subject: Engine Swap Track Results are in. Post your performance predictions by wesmigletz on 2008/11/23 4:51:24 Didn't actually road test the new engine until last night. An assortment of mishaps and defective new parts contributed to the time crunch. Anyway, we made it to the track and back. I'll post the A and B combos, but I will save my driving impressions and track results until we see some of the predictions.
