Another "which engine to buy"-question

[Alex396ss]

Hi!

Need some help with which engine to buy for my ´67 Chevelle project.

https://lateral-g.net/forums/showthread.php4?t=6709

I´d really like a fuelinjected bigblock, like the 502 or a 572 and I´m going for some kind of 6-speed.
But I don´t want to mess up the car´s handling because of the weightissues.
I´m thinking of spending 10.000-15.000$$ on the engine and I´d like to have around 600+ horses.
It won´t be a daily driver, but I´d also like to use it in heavy traffic and on longer trips, so it has to be reliable.

Any suggestions and thoughts would be appreciated!
