Contrary to popular belief, the 179 block and the 179HP blocks are the same block. They are not all that rare so if that one is cactus, another should not be that hard to find.

From my days of playing with holden reds, i was to believe the hp had a steel crank and thicker bores.Quote:

All 6's had steel cranks upto around the HR IIRC.Quote:

Thanks Gents. I’ll clean everything up , take a look at the valves and keep an eye out for a runner. Its more about the learning process for me - but not at any cost!
Would the 202 or 186 just drop in or would there be further adapter work involved does anyone know?
cheers,

Straight drop in for the 202 and 186.
BUT 202 and 186 are reputed to not rev as well as a 179 and don't like the revs with LR low gearing at highway speed.
Of course ideal would be a 12 port head engine from a VE? Commodore

how nasty do you want to be making it run?Quote:

Blimey, don't make this harder than it needs to be. Red motors don't usually bend valves from piston contact. Liberally dose the bores with light oil and spin the motor over on the starter. The head can be as easy or as hard as you like. Spray penetrating oil liberally into the ports and tap each valve at the spring end with a medium hammer. If they're slightly stuck just tap away and oil until they're free. Or go the whole hog and dismantle the valves and do a valve grind with some lapping paste. One head gasket set, give the head and block faces a good clean and chuck it back together. Whatever you do don't spend up on outsourced labour, so long as it runs it'll do for your purposes.
So they say, but I've run both a 202 and 186 in series landies and they run and rev fine in this application IMO.Quote:
