I have a customer who wants to get rid of this tired 289 and drop in something powerful. But a street car, with air.. I was thinking about 302 punched out and bored and stroked. 331-347... Or 351 same combo 408
.. Then I got an idea about big blocks. 390 and up.. Need to know what will work the best and what trans to match it up with... Any info or personal preference will be greatly appreciated.. This is a very clean car and money really isn't an issue.. Pretty much a firewall forward resto..
