Motor mount adapters - ‘69 428 in ‘70 Trans Am

Yeah, I ran the 428 in my ‘67 from 2002-2013, then I sent that car down to Steve Barr for a full frame-off and put the original 400 HO back in. The 428 has just been under my bench for past few...

The 428 I am going to run has a SuperDamper on it so it requires a 3-bolt crank pulley. I bought one from RamAir Restorations. Very nice billet piece. I did a trial fit with the p/s pump and it...

Found an older thread from HFR and he gave the GM part no. 3899021, and that OER reproduces that. Thanks.

Does anyone have a picture, or at least an accurate length, for the clutch return spring (from clutch fork to small bracket on the frame). That spring went missing with my clutch fork. I bought a...

I noticed that the Z-bar fitting that screws into the block on the ‘69 428 that was in my GTO is longer than the firing that was on my ‘70 400 in my TA. I am assuming that the Z-bars are a little...

Motor mount adapters - ‘69 428 in ‘70 Trans Am

Was able to get the engine in today. By ‘in’ I mean get the bolt through the passenger side mount. Did it with the car on the lift and a friend of mine used a pry bar to pull down on mount while I...

Motor mount adapters - ‘69 428 in ‘70 Trans Am

Another question. On the driver side, the strap iron does not sit flush. The welded nut that the motor mount bolts to hits a casting rib on the block. As a result, the strap is twisted a bit. Am I...
