Default 428 swap update
Well I知 making good progress on my 350 to 428 swap. Tranny should be back from the shop next week. I知 dying to start it!!

I知 worried about clearance for the distributor but we値l see when the tranny is in. If it痴 a big issue I知 put the old points dizzy back in until I get it going.

Had decent clearance in my 69 firebird for the HEI. You might want to pull it out when you install the tranny though. Makes it easier to install those top 2 tranny bolts .
