but still, compared to stock, shaving the head will improve squish correct? But you run into the limits of how thick the head gasket is and thus need to deck the block to make up for it... Makes sense now that I think a little more about it =D. And actually, i was just reading, and still am, about someone on TB building up a b21ft for higher compression and good squish and crap. So my understanding of it's growing. I was also thinking about my 74 engine, and it's future buildup... And got to thinking something along the lines of the engine you're describing, the 2036. I'm not sure if I should worry about going .040 over rather than .030 because what if i need to rebuild the engine again and i'd need to oversize it that much more because over a .040 boring costs more and is rarer, unless I go with b21 pistons, which is actually what I've always wanted to do, but might not end up doing. So yeah, i guess if the engine's done well, i shouldn't worry about going .040 over rather than .030.
That clearance of .030 sounds pretty darn low... How low exactly are you talking about for his rpm range? I don't really know how much stretch really comes into play, but yeah, that number's a bit lower than what i've seen elsewhere, and your .032 sounds lowish almost too, but i guess it's alright. How high have you spun your MPPE up to? What rpm did you figure was high enough? I want something that'll run up to 7k, use HIF6 carbs to their max, and be good. As in, possibly something hotter than V-performance's regular street performance kit, but still with SUs. And of course a properly modified head. Along with M rods and blah blah. Possibly a custom ground cam as well... I was actually just looking at KGTrimming's catologs and saw that they're street performance head comes with 37mm exhaust valves where as JP uses 36mm, and stock is 35... But this is going to be a big topic and one i shouldn't really get myself involved in because this won't be happening for two years at the least...
=D I love this stuff! If only school wasn't a factor, i'd be doing it this coming summer. And probably drive up to Canada to do it all with Rhys or something. Oh well.
EDIT: Anywho, also, what camshafts are you using on your MPPE and what are you planning to use on the 2036? Are your rockers modified at all?
