View Full Version : Gen V big block heads on a Mark IV block... RacerRick 06-08-2005, 10:30:00 AM Gen V big block heads on a Mark IV block... Can this be done? Does it require a special gasket? If so, does anyone have a source and part number? rscamaro73 06-08-2005, 12:05:00 PM Id get ahold of one of the GM Performance Parts dealers and ask them. Greenwold ; Scoggins-Dickey ; Pace Just look in the back of a car rag http://www.nastyz28.com/ubb/wink.gif 73454 06-08-2005, 01:36:00 PM I never did get that answer either. pdq67 06-08-2005, 09:40:00 PM I think Scoggin Dickey sells a little copper headgasket washer plug kit to do this if not mistaken??? pdq67 rscamaro73 06-08-2005, 11:31:00 PM I know one of the Gen 5/6 blocks you can't use Mk IV heads on....I think its 5....and the 6 you can, but with a special head gasket. It was in a car rag a LONG time ago I believe. I can go visit my local machine shop tomorrow (if I remember) and ask them.... sinner4 06-10-2005, 01:03:00 AM What is a V gen BBC?? 2000 something unit?. Mark IV is the normal BBC? 366 Truck (Tall Deck), 396, 402 427, 427 Truck(Tall Deck), 454 Stroked 427, 454, 496, 502 Board out 454, 510 Stroked 454 all should be the same. rscamaro73 06-10-2005, 10:00:00 AM The actual block design is different. Gen 5 blocks have no mach fuel pump Gen 6 starts back up with it and is made for roller cams. The MkIV is 'old school BBC' as we mostly know http://www.nastyz28.com/ubb/wink.gif ------------------ 73 LT 454 http://www.cardomain.com/id/rscamaro73 http://community.webshots.com/user/rscamaro73 |
