One step closer to regretting my decisions!!!!

The good news is the black valve covers should fit! That should make it a no brainier!

The car does have ac in it and I’d like to keep it. So it limits the valve covers I can use.

If they are the cast aluminum ones with the angled sides they will fit, mine did with zero modification and could still get them on and off in the car

There is so much WIN in this thread, I can't believe a small block was even mentioned.
There is no replacement for displacement (except for massive boost pressure).

Only issue to contend with is if they’ll clear the roller rockers on the engine.

They cleared mine ( harland sharps at first then switched to Crane) just had to use the short poly locks. Mercruiser also uses roller rockers with those valve covers

Theres old crane golds on it now. Not sure what poly locks it has.

If it has Crane gold rockers on it now with those valve covers it should have the short poly locks. I had no problem with ac box clearance but I guess there is always that chance that every car is slightly different. I'll see if I can find a pic, I have since switched it to heat only

I have Crane Golds on my 498 BBC. I used a 1/2 inch spacer under the stock valve covers with no issues with rockers touching the valve covers. Also, this setup cleared the A/C box. I can still remove the valve covers with no problem.

Big blocks suck, they make all this power and torque and then they look impressive and intimidating when you open the hood, I don't know why anyone would want one in a Gbody. 😉

Haha.

Big blocks mean big money, more torque before 4k rpm's than their little brothers make at 6500, more bragging rights, and.................

more envy from us non big block people.

Someday before I leave this old crappy planet I want to build a stout 496ish aluminum headed Chev and make 1500hp with 12 psi of boost with two giant melon sized turbos on each side that will remind you of Dolly Parton when the hood gets opened. Mild compression 10-11:1 with a mid range cam and run it on E.
