Ok where to start....i'm looking for advice on a combination that someone is using that works with 2.56:1 diff gears. My 69fb just doesnt move ike it should. No neck snapper off the line (2.56:1 see's to that) but from 50mph on , she flys. Perfect for our 110kph (about 65-70 mph speed limit)
I currently have a 400, TH350 and peg leg 10 bolt (2.56:1).The 400 has mild work done to it (big valve #16 heads, Comp XE268H 51-232-3 cam (old grind) and valve train, Edelbrock RPM, Hooker long brach headers 650dp Holley and HEI. The tranny is a new stock TH350 with stock converter.
I realise i could change my diff ratio to work better with my cam but the 'long legs' really work for me. ( i travel about 70 miles on the hiway daily ).... ( no im not buying a Hyundai as the wife keeps begging me to do)
Should i change cams (would rather not) , buy a stall converter ( ??? stall speed) or search for a diff with maybe 3.08's
Id appreciate any advice and welcome input from anyone running a similar combination or doing big miles frequently.
