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
Paul
