Thanks for the interest in BluePrint Engines. I'm the Products Manager of the company. Happy to help.
1. how are stroker motors for "regular" driving on the street? can you drive these like a OEM motor without any real tuning/reliability issues?
All of our engines are pump gas, streetable, extremely reliable, offerings. All BluePrint Engines come with a 30 month warranty, as well as fully dyno tested.
2. is your 408 10.5 compression so it runs on pump gas?
We have several versions. All pump gas friendly. Please see link at bottom of page
3. are there different "sizes" of 340 strokers?
340 blocks are very hard to come by. Starting with a 360, we build our 408 stroker.
4. are 360 blocks better to do a stroker with instead of a 340?
In my opinion yes, because the blocks we use are roller cam ready. I love our aluminum head, roller cam version. Which is what the OP has.
5. Pricing and options are in the link below. Things to consider with any performance engine, is that the rest of the car also needs ready for the HP (mainly trans and Torque converter).
You may even be a good contender for our complete 408/727 complete package. Assuming your trans may be bone stock.
