Default New Motor Recommendations

My brother needs a new motor for his '81 vette (it currently has the base motor...not the L82). The motor is blowing quite a bit of smoke and the car is too slow for his liking, so he has decided to put a new engine in there and crate the original motor.

He asked me what I thought he should put in and I pointed him in this direction...

My cars are original motor cars so I've never been though this before, but I've heard a lot of people say good things about the 383 stroker which is why I was thinking that would be a good choice. But before he buys something I wanted to ask people here who can probably offer him better advice than me. If at all possible he'd like to not have to change too many drivetrain components. I know he recently bought a new carb and is going to need headers, but besides the motor he's hoping to not have to replace too much else.

Thoughts? Thanks in advance.

well to get the real benefit from the 383 you will need a higher rates stall converter in the tranny ..and better gearing will help. a better flowing intake and carb as well as exhaust are also a must or your wasting a lot of potential gains of the bigger stroke.
I also decided to store my original engine in my 74 and found building my own 4 bolt 355 from scratch is actually a LOT easier and cheaper than I ever thought plus there a lot of satisfaction in learning to do it yourself.... The engine is not in the car yet but it should put out roughly 375-390hp and over 400lbs or torque and thanks to ebay,summit and Craigslist it cost me about grand to build

I went with a zz4 GM crate engine in my 71. Has more than enough power for me and has been rock solid dependable.
