I'll be interested to hear your tale of the install. By the way, if you're running a 904, you can use the Mopar mini starter according to TTI. The Powermaster starter is only required if you have a 727 or a 4 speed with a 130 tooth flywheel.
Not sure if you're right about that Lee. The 340 has a different flywheel than a stock 273 with a 904. That was the motor they used to mock up the headers. 318/340/360/408 requires the powermaster.
SB 66 Valiant....I have some pictures of my tti's mocked up on my 340 on my resto page with the lakewood bellhousing. The tube on the driver's side does hit the thicker/taller valve covers. I have the mopar performance aluminum valve covers and it hits. You can use an extra gasket or trim the valve cover which is what I eventually did. Good luck with the install. With all the extra hand get some good pics for us. :thumbup:
