That's because they are
What's the part number on the block? Thanks
That's because they are
05-10 3V blocks (same as Aluminator blocks) are the strongest Aluminum block on the market, but it's marginal at best over the Teksid IMO. In terms of cost, it's hard to beat the Teksid.
JM uses the Teksid, but it's far from stock, so you can't really compare that to a street prepped engine.
I spoke to John the other day for 45 min. His block, not sleeved, not filled, stock main caps. He did use larger side bolts with a main girdle.
At what point do you worry about block failure with a Teksid or 05-10 block for that matter?
I'm not worried about my convertible build as it just will be a Vortech V1 Si. My Cobra is a different story with the plan being twin Precision 6062Gen IIs
You won't have to worry, either of those blocks will easily handle the power of those twins (assuming everything else is up to par).
