Seems a little slow...

I know all about budget and things are all to often "use what ya got", but I believe the 727 is hurting you're et.

A couple of people I know switched from the 727 to the 904 and in the eighth mile they lost 3 tenths. It is noted that a 904 will take up around 25hp to turn as to where a 727 will take close to 50hp to operate. A 727 is good, but these are just observations through trial and error. My friend went to a 727 and it killed the bottom end on his 318. Is the TCI valve body a full reverse manual?

The rest of the combo looks real good IMO.
