i have the 408 base, I very pleased with the einge about 3500 miles on it now.

2 problems i had with it was they didn't index the intermediate shaft correctly but no big deal.

Then the dipstick hit the crank but that might of been my fault b/c i removed the tub and stick and bent it a little when i reinstalled it.

For the money imo you get get alot better parts then the turn key offers.
