were they 308H Blocks from the 1969/1970 HT-HG Monaro, as some of them 308H Blocks were ment to have steel-cranks
Any one know what type of Block that the F5000 Repco 308 V8 used ?????

i wasent sure, as the 308H Engine was Holden's first 308 V8, I thought Repco might of used them blocks

you would think the L34 Block would be close to the F5000 Repco V8 Block, due to Repco playing apart with the L34 Engine, did the L34 Engine use the F5000 Flat Top Pistons ??

Alan, the 308H blocks were mainly in HT and HG Brougham, and they are not really any different to HQ blocks. Apart from the timing chain cover mounted oil filler, sump/pickup and heads they are just about identical. The early blocks (almost exclusively HT Brougham) had HP cast into the side. Some of these made their way into Belmont, Kingswood, Monaro, Monaro GTS and Premier once 307's ran out but not long after the castings changed to 308 on one side just like they stayed until around VK introduction. The reason some forged crankshafts have turned up will be because these engines were under development prior to GMH's new nodular iron foundry opening in 1967, so naturally some of the early cranks will be forged just like all red motor cranks were prior to around 4/67. As GMH were a business they never wasted anything, so any development stuff left laying around that was good to use went into production engines. The fact that the early 253's are blank on the side and 308's had HP gives you a timeframe as to when these castings were finalised. Just look at the EH-HD era engines: 149 were blank and 179 had HP until it was replaced with 179 at some stage. Later 161's in HR were also blank afaik. Just remember that 308 was only available in Brougham from release until late in 1969 so it was a low volume engine until it was made available across the HT series range. This possibly explains the apparant protracted changeover period from HP to 308 as new castings were introduced to cope with the increased demand for the 308 engine.

As far as I am aware the F5000 blocks were just early versions of the re-designed HJ block. The ones I have known of were cast early in 1973 (like 3/73 or 5/73 or thereabouts). Most of these appear to have an X on them. The same design was used in L34. They were GMH cast blocks, at least they were GMH castings afaik.

So all the blocks upto and including HQ would have been neo seal/crank and HJ and on, including L34 and 5000 blocks would have been rope seal and crank.
