360 into early A, best ex manifolds

I've heard some glowing reports on Dougs & alot of bad on TTI's & yes the 273 logs would suffocate it. I do have some Hooker 5208's but since this 408 is going to be a mild daily driver I will try like Hell to get some magnums to fit. thank guys. RR
If automatic Sanderson dd9 all good.
