OK, I got you started but I am more in the learning camp than solving remote problems on the 350 which I am learning myself. As I recall the quadrajet was rated at 750 cfm (?) but you have one on there. Folks on this Forum have not been favorable regarding the Autozone engines, although I must confess I almost bought one myself, but the engine apparently runs OK up to a certain rpm AND the 3.73 rear gear ought to be able to permit rapid acceleration. Maybe the HEI is reaching it's rpm limit at about 5000 and then starting to fail, but you say you can shift into 2nd and manually down shift OK, so that leads me to the T350 trans and it's shift points. How old is the HEI? There are inexpensive kits to improve the HEI for about $20 and that might be worth trying, but here is my own limited suggestion: have a trans shop check out the shift points on the T350 and let them set the down shift where they think it needs to be. That's passing the buck until someone else here has a better suggestion. And to think I will have to sort this out soon myself!
