I am indexing my bell housing to my new Dart block, I have a world class T5 and cannot find the specs for centering. Does this look ok or will i need offset dowl pins. All are positive numbers the - if only a marker. Will also check the flywheel for run-out, what are the specs for that ?

I don’t have the specs but look up the quick time instructions for the t5 bell or tko bell and I’ll bet it’s in the indexing part

You Halve that 010 which gives you a 005 which is the max on a TKX... The T5 is less picky, as least that is my understanding and why we never indexed them in the past....... Ball bearing VS a tapered roller bearing in the front of the trans?.......

Good video and written explanation on Holley's website here:

How To Align Your Bellhousing For Maximum Transmission And Clutch Life

You should align your bellhousing and transmission when mating them up to make sure that there isn't a bind when you go for that heroic shift. Nobody wants to be the guy who misses a shift, and you don't want to be the person tearing things apart for a damage inspection!
