On-center 153, S2 6-bolt heads are a must. Else is negotiable.

Heads are GN1R. I have whole BGC setup for off-center but new block is on-center. So even only lower intake without everything else will do.

Those are for SII heads according to the Power Source book, I have GN1R heads.

I also need on-center lower intake. I have the whole BGC off-center one with doghouse, rails etc, but switched to on-center and the lower one needs to be swapped. PM if you have anything.

I think I could get a set of Carrillo sd-s locally, but the weight difference is holding me back. There are no balancing shops here, so I need to send it to balancing abroad for that.

Hi, long story short, My SII Off-center block finally gave up and I got a new one witch is SII On-center. Now, can I use the current Off-center Oliver rods in there and if yes, how much HP potential I lose? Thanks.

Okay, the "slap" is actually piston kissing the head in good english;) Anyhow, ordered new head gaskets 0.070" thick instead of 0.045" thick, that should cure the issue. Got the crank back from machining and measured the alignment of the pullies, the cam sprocket is more sinked 1mm(0.040")...

More teardown questions. Is this half-moon shaped thing at the lower-right I see a piston-slap?

I have 5 sleeves. Last sleeving at #1 made the #3 sleeve come loose. Attached some loctite sleeve retainer and in it went. Held up to 900hp and will be tortured 1100+ next year. I have used Melling CCSL136HP sleeves all the time, worked like a charm all the time. Talk to Dan at melling, he has...

The oil slinger is in the wrong end of the timing gear, I need something between the crank and the sprocket, not between the sprocket and the damper nose. But I think I'll drop the crank off to the machinist and tell him to cut a ledge to the #1 main bearing race. That would solve the issues...

Where could I acquire one? or just mill one from a leftover sprocket? It is quite true, I would prefer getting it even closer to the block, since I have the fuel pump pushrod interference issue. Third chain in ~50 passes :) Last year I also broke one but was to newb to notice the pin...

Pic of the crank #1 bearing where the chain pins have made their mark. What can I do about it? grind the #1 race down?

Thanks, that ROL150 was what I had, It looks like the -D option does not have bearing.

I think I'm getting closer to the stiffness issue. The #1 main on the BMS crank has nicks on the side so the chain pins have defiantly contacted crank. But what can I do about it? is there a spacer for the smaller sprocket or should I machine down the #1 main a little? Has anyone had the same...

Firstly, where to get the cam bolt that would have an integral roller bearing on the bolt head. I had this when I aquired the engine but broke it and substituted to a normal one. It is clearly rubbing the front cover and I cant shim it less. I'm using racepumps fuel pump, and the tolerance...
