I'm kinda mad at myself for not trying my TW on the 390December 3 2017 at 10:11 AM

Response to How much motor do you need to effectively use a Tunnel Wedge?
I had the 390 apart last winter and considered trying the TW but it's nicely bolted on to a 428 I have sitting here as a spare motor and I was too lazy to take it off. MY TW is a Dove with a bit of work done and the 390 has a Stock BT MR 2x4 so it likely would have gained a little. Maybe not enough to justify the gaskets though. I'd run either on a street engine just for looks.
