I dont know about overall E.T, but the A518 will give you a better 60 foot time due to the lower gear ratio in the planetary gear set! I think the A518 has a 2.74 low gear where the 727 is either a 2.45 or 2.54...cant remember!




Old thread....

With the 727 and 4K converter I picked up 5 tenths on my 60 foot times...I easily picked up 8 tenths on my 1/4 mile times, but I was falling flat on my nose. Now with a better cam designed for my heads, a 4bbl M1 and 58mm TB, it's running high 12's, was running low 14's to 13.8.




Was that 5 tenths along with other changes? How much do you think the Caltracs played into that pick up on your 60 ft?

I can see where there is a lot of rotating mass removed , the power goes straight thru the OD section but it does spin all that weight and the slight drag of the OD clutches .




I'd say the 5 tenths was due to the 4k converter and 727. I wish I would have run it a few times with out the Monos and Caltracs. But I never spun with the built 46RE and 2800 converter, so I can't say I picked up any in the traction department.

But....trying to make ths clear, I bet the 727 & 4K stall would have taxed the non monoleaf/caltrac set up I ran with the 46RE.
