It'* very possible the parts will hold. However they were designed differently on purpose, maybe it was only overkill. We'll see in enough mileage on these swaps.
I totally agree with BillBoost on this, I guess will all find out.
Did you read my last post???
Take a look on clubgp and look at all the guys running L36 bottom ends in their GTP'*. Hell, just make a post asking who all has an L36 bottom end and what mileage they've had it with their M90 and see what they say. As far as longevity I don't see it being an issue?
I mean really how much weaker would you think the L36 bottom end is compared to the L67? There are L67 bottom ends that have been holding up to consistant 10 second passes for a while now. 11 second L67'* are FAR from unheard of and there are plenty of them on clubgp as peoples daily drivers that have been that way for years wtih no issues. L67 bottoms, for a stock bottom end, are essentially bulletproof (as long as you are being smart about it, not getting KR, etc...). Jamhoney on clubgp has been running 11'* since not too long after he bought the car new. It runs 11.2'* on stock L67 bottom end and its his daily driver. It isn't the original shortblock, however it was put in when the car was running mid 13'* and blew up due to the Intense PCM issues that '04s originally had IIRC.
