2. About how much would a complete motor buildup be with good components?
3. How long does it take to get one?
Every engine build is unique for each customer, so the price is determined by their specific details.
But to give a typical price on a TA alum block build with forged internals, I usually quote ~$10K for parts and labor including roller cam. If billet internals are specified, this increases by $3-4K.
Add the price for TA heads with all needed accesories like roller rockers, valve covers, pushrods, etc., and this will add $3-6K to the short block price above.
Then items like intake, front cover/oil pump, oil pan and other misc. items are still needed.
The time to build is determined by special order parts lead time. For example, all our pistons are custom built for us by CP, and can take from 3-8 weeks depending on piston specs. The time to machine, fit and assemble an engine like this is usually 2 weeks when all parts are in-house.
We built the protype TA alum block years ago, and have done many TA, and other alum blocks, since then.
