which toploader with FE??
Hi Guys, can anyone tell me the general difference between toploaders. not the gears or splines. I am wondering the difference between big block and small block. also why are truck toploaders so cheap. Can they be used in a 428 cobra? can a small block loader be used with the 428?

AZ, The main external diff between BB and SB toploaders is the size of the input/output splines; along with internal changes, the BB toploaders have a higher torque capacity. The cases may be the same or very similar. Check with David Kee.
I was told that the truck toploaders have a low-low first gear (grandma). They could no doubt be used behind a 428, but you might want to add a drawbar so you could plow or pull stumps with it (:LOL: :MECOOL: :LOL: ). The small toploader can/has been used behind 428s, and would do okay for mild street use, as long as the tires didn't hook up. Comments, guys? |
Toploaders
All toploaders - same case, same major internals except whats listed below (not counting gear ratios for wide/close ratio and length differences / tailshaft housing)
Small block and 390 FE toploaders - Small input and output shaft, but like I said above, gear sets are same as 427/428, other than in/out shaft (390 is same as small block box but slightly shorter input for FE, small block can be cut) 427/428 - Bigger input and output shaft, same case, same gear sets Truck toploader - Think 3 speed with overdrive. Limited shifter options, wider ratio step. I havent messed with these but no-one is using them, that must be an indication In a light Cobra, under 450 horse, I'd say the small block or 390 is plenty. If you are running slicks, go with a big input/output Bottom line, aside from in/out shafts and overall lengths, all toploaders are the same, so there are no "internal differences" that make them stronger, just the input and output |
Call David Kee.The truck toploaderhas different gear ratios.
I have a NASCAR Toploader from David.He changed it to a wide-ratio so it works perfect with my 3.27 gears.:D |
