I too, would want a 455 in that car, BUT my main concern would be to get it on the road asap...which is where I think you stand.
The current condition of the valve seats would tell me whether or not to install new hardened seats. I'm a fan of hardened seats BUT yours might not be that bad.. If you use the 068 cam (Melling SPC7) it is not terribly expensive, you can use stock springs, thats a huge easy happening deal...And its a great cam for many engines, especially a 400. stock rockers will be fine with that, unless you want to step up to stamped 1.65 rockers...

I would put the 400 in, then plan on putting a 455 in eventually.

I just traded off a set of #62 heads last month, but they are easy to find under $500 a pair around here. Its easy to get sucked into chasing the perfect combo, my philosophy is the engineers that designed these didna good job so I’ll jus massage their parts a bit for my needs.

if you want to run 13.0 in the 1/4, with the 455 cid motor, I wonder what everyone thinks about the 744 cam? That one seems to get overlooked. May even need more than that to get to 13??

My 78 Clone, with 455HO block and heads, just a H-O Racing RAIV clone cam Similar to his old HC-03D I believe, TH400, Stock converter, 3.08 rears on 26" street tires was getting 2 sec 60ft times(1.99sec was my best ever), and 12.4@106mph through the lights. Or might have been 12.6@104. Also got 16MPG+ when driven smooth. I even towed a trailer to and from the strip with all our camping gear, tools etc etc with the car, It was my only driver at the time. About 140Mi each way.

My '74 has the # matching 400 stroked to 461 with # match 4x heads, performer intake, numbers matching Q-jet (Cliff), and hooker headers, mild XE268 cam (idles at 600 rpm), 3.23 rear, super T-10. I got the mph to run low 13's, but traction is a major problem with, even with the Nitto 555 255/50/17's. I feel I will break stuff like rear end and tranny if I go to slicks. I vote you stroke it

If I could find a good 455 locally that is the route I'd go, the stroker is a non-starter, $4000 into an engine right off the bat isn't what I want to spend and at that point I could do an LS swap and make more power. I'm keeping my eyes open for a different set of heads to get to 9.1 compression but if I don't have a set when re-ringing the engine starts I'll run the 4x-4 and so a swap later on down the road. The main goal is to get it back on the road and make it reliable. I like everyone's ideas because it give a guy things to think about that I hadn't looked at before.
