I have used a couple of their engines in customers cars and not had any problems. Their tech support is excellent. I recently bought a big inch small block shortblock but have no experience with their big locks. FWIW

Several good videos on Youtube about Blue Print Engines now... looks like a nice operation.

I'd use one in my car if needed.

I purchased the Blueprint 4001CTC1 engine with Holley EFI for my build. As I have yet to fire it up nothing leads e to believe I'll have any issues.
Good Luck !

I dropped in the Blueprint SBC BP3503CTC1 and the Tremec 5 Speed this fall into my 74
Dyno sheet was 381Hp 406 ft lbs torque
I got my break in miles in before the winter and I'm am very happy with the upgrade in power and also the overdrive
Plenty of power on the highways and I cant say enough about cruising at lower RPM's

Its a different animal all together.,
