Not really but that kind of diminishes the value to a certain extent being bored almost 70 over. When I bought my 421 it was standard bore, and still needed to go 4.135” to make up for some dummy who...

Absolutely not 421 pistons. The valve reliefs are completely different on a 421.

The valve reliefs and dish shown are what forged 428 replacement TRW/Sealed Power 12cc pistons all look like.

Standard bore size is 4.09375” for the 421.

4.120” is standard bore for the 428.

4.160” is +.040” for the 428 pistons so you’re poking that 421 .06625” over which seems excessive unless the...

I once tried to switch from 10x28” slicks to 9x29” (15x8.5” wheels) on my ‘64 GTO bracket car. A total no-go, just way too tall.

The crossmember will be tilted rearward at a very slight angle when you slide it back if you retain the stock rubber insulators and clamp mounting. This presents zero issues.

Short shaft like the A-body cars.

The ‘69 GP sits on what’s essentially an A-body chassis stretched 6” ahead of the engine.

Former ‘69 GP owner here so I’m not guessing. ;)
