1998 FF build

[blackmaxonly]

I have a blown front half of a '99 FF blocks if you want that paperweight too

[Merc 2.5]

Well I think my plan for this to be a budget build has gone out the window. I just picked up a 7 petal front half from a 2.5 240 HP Sport jet. Should bolt right on my FF block. The only real difference I see is there is 1 less bleed fitting on the 7 petal front. The way the EFI bleed system is routed, it wont matter if I bypass it. Or I could drill it and install the fitting. Just got to make sure the crankshaft sealing rings don't bind. The 5 petal front has a little more wear then the 7 petal. The guy said there was some damage on it. So I negotiated pretty hard with him. I thought I was going to have to repair it. Didn't realize the damage was already fixed. Not perfect, but good enough to be used the way it is.

I was just talking to my machinist about promax block and it had sealing ring land broke off and tore up , said it could be fixed but will take alot of work ( welding and re cutting etc) just make sure the repair is done right

I obviously misunderstood what the guy was saying about this 7 petal front. I thought it still needed repair. Apparently he meant it was repaired a long time ago. This is not a new repair. it is old. It has been used in a rebuilt motor already. The crankshaft sealing ring fits perfectly.

I spoke to Chris the other day. He said he should be sending my block back to me next week. All the hard parts I sent him will cover 5/6 of the bill. Now that I am using a 7 petal front, I am getting the pistons with thin rings. 1.5mm vs 2mm. I should be able to spin this motor up pretty high without a problem.

I have a front half from a 1996 150 you can have. It has the same casting number as my 1998 FF front half.
