11.50@117 crosses at 55-5600,94 mph at 1/8th, 3.89 gear, 29" tire,It's either fuel related or more than likely too much slippage from the convertor

This isn't a rule or anything, but when comparing time slips with a few others, mine being the slowest at 13.3, the quickest running low 11's, the mph averaged a 23%-26% increase from the 1/8th to the 1/4th. Your's is around 18%. Definitely looks like there should be more mph in the 1/4 to me.

Good luck to the new owner of the Ventura II! Sold the car after 13+ years. Look for it on the Hot Rod Power Tour in the future as it's currently being re-configured as a Pro-Touring ride!
