I am in the process of building a motor and looking for help in determining where I end up.
1) To be period correct, it needs to be an FE. But my budget can't afford a side oiler.
2) I have a 68 360 truck motor, that appears to be bore-able a slight more, maybe to 4.13. I have a good 390 crank for that block. I need to buy rods and pistons.
My options are to build it as a 390, bore it (assuming it will pass sonic) to get to 406. If it will go to 406, I could add a 428 crank to be a 428. Or I could stroke the 390 to come in around 430.
My hang up is the badge on the side of the car says "427" 390 or 406 won't pass this test - it becomes a pride thing. 428 or 430 would at least satisfy that test.
I don't see a lot of guys running 390 strokers so there isn't a lot of "this is how I did it" out there.
Can anyone throw out ideas to help me with the decision? I have a friend who has a Superformance with a 347. His regret is he didn't go to 427. Don't want to finish the car and end up with "builders remorse"
The car will strictly be a cruiser. Only looking for moderate street performance. The 390 would be more than enough power, if that is the wisest move. But I am trying to build it as period accurate as possible.
Dollar wise, each cubic inch = $$. 390 obviously would be the cheapiest. But since I already have to buy rods and pistons and probably grind the crank, the difference to the 428 or the stroker kit isn't that far off.
Comments or suggestions
Thanks

Which way to go - 390 406 428 stroker
