GT70 P trim here.

Heavy street car works fine since it's BB, 3200 stall.

Pump gas and alky. only run about 25psi.

No issues at all, better than the TA62 I had on there.

My opinion is to get the use out of the 67 over a 61 you have to have your heads ported and polished. To much obstruction on stock heads and that will just lead to blowing hotter air.

I got a brand new John Craig rebuilt PT54 (224 miles) that I would trade you with some cash, because I'm looking to upgrade.
