Stroker Performance Review

Have you actually checked the flash stall on the converter? I'd think it would 60' better than 1.71 even with the converter that's in it. Do you have a fuel pressure gauge that you can see while going down track? I'm guessing you have the secondary PV plugged? My engine pulls around 3" of vacuum at idle and IIRC there is a 6" PV on the primary side with the secondary plugged.

My current engine and the one before it was happier with 21-22° initial timing than 15-18°. Do you know anyone with a 850 or 950 that you can borrow to see how the car reacts? Don't be afraid to try different shift points, it'll let you know where it's happiest. Try leaving at idle and see if the converter works better.

Keep after at it, you'll get it tuned up. :BangHead:
