JohnZ Jun 22nd, 08, 04:39 PM '68-'69 are the same, '67 was different. :thumbsup: Unreal Jun 23rd, 08, 03:38 PM John, A guy on Yenkos.net said that he found the big block heater box to be about 1/4" wider than the small block one. Seems crazy that GM would have two, so similar, but I don't know. Can you shed some light? stamatisg1977 Jun 23rd, 08, 04:31 PM do you need one? i have a 69 heater box with floor vent in excellent condition. i recently smoothed my firewall. i had it on ebay nut no bites. Codi Jun 23rd, 08, 04:54 PM I rebuilt my 69 heater box and converted from a SB to a BB. The only diff i could see was the heater core. 400bird Jun 23rd, 08, 08:05 PM John, A guy on Yenkos.net said that he found the big block heater box to be about 1/4" wider than the small block one.

I think the main difference is that on a BB the heater hose connections go right through the middle of the cover (so there are 2 large holes), SB they are outside the box on the engine side. |
