The coolest things ,about Pontiac ? Everything pre somg was interchangeable. Other than the '66 -'67 valve change angles ( If I remember , correctly...), Engines were designed , to be killer torque monsters. Had a '72 Formula Firebird , that I traded a '69We've all tried to explain to him several times that Pontiac did not make s 307. He ain't gettin it.
Stuff a Well designed 455 in it , reconciliation of turbo designed..will make life FUN. Now ,those pesky smog laws.Had an Indy 500 edition Firechicken in the shop not that long ago, 4.9 Litre Turbo, oddly configured intake ports. All I know is they were a snack for My Buddy's 400 T/A,
around '83 or so, not close. The turbo doesn't look any bigger than a T-type Buick, We had an early T-type Riviera, think it was an '83 I think.......
The Guy with the Catalina spun a rod brg. in the 400, so He dropped a 301 in to run around while he built a 455 for it, talk about ridin' a torque curve rollercoaster!!!
