Re: Project Lex

Picked up some basic BC Single Springs w/ Ti Retainers from a guy who decided to go a different route. Brand new but for about $100 less than from a vendor, so that makes me . General consensus is these should be good for 8k RPM, even on the stock shim over bucket arrangement. So that's my plan for the head. And compared to stock redline of 6500 on my car, and I'm revving my current setup to 7300, so this is pretty much the best bang for the buck arrangement I came up with, which is the goal of this build to be quality while also spending wisely without overspending, and I'm plenty happy with 8k, doubt i'll even go that high and probably stay just slightly under that just to be conservative.


Next I got the motor stripped down mostly here. Dan said that's good enough, so I'll hopefully be bringing this to him within maybe a month or so to start work on the block.


Next, I got the issue figured out with the engine not turning over. Long story short, the flywheel bolts were just a tish too long. So I torqued the flywheel down, but the bottoms of the bolts must also have bottomed out on the main cap on the other said of the crank flange, preventing the motor from turning. I was able to stack a few washers under the bolt head to get it to clear, but I will be ordering 35mm bolts so I have the correct size. The stock flexplate arrangement, I measured has about 12.8mm of thread protruding. You can see the pic of 17mm protruding which did not work. But with washers, the 14.8mm protrusion works fine. Once I order the 35mm bolts, it should have roughly 13.8mm protruding, which is about 1mm more than stock, but also about 1mm less than the 14.8 that I know works, so should work out good.

Stock Flexplate w/ spacers and stock bolt (12.8mm protruding)


40mm with 2 washers, does not work and bottoms out on main cap (17.0mm protruding)


40mm with 3 washers, works/clears (14.8mm protruding)


Oh and last thing, it's alive.
