88 suburban 350 rebuild questions.

Going off my previous thread. I did further digging into the build in my burb. Not much but what I could with the heads off. So the stroke was done to 3.562 with .040 oversize flat top pistons with valve reliefs. The heads are the stock 810 with oversized intake and exhaust valves. Making the engine a 365 ci. Only thing I’ve found is these builds are typically circle track motors or old school stroker. What would you do if it was your motor?

Without any other infor in this thread, it would depend on what I wanted my Suburban to do. I am an old school guy; I rebuild them as they originally were with better breathing heads and maybe a little hair on the cam and send it. I'd sell the dirt track block and put the money into another one.
I'm betting that isn't you.

What is your goal for the engine ( what will you use the Suburban for), and what is your budget?

Most significant weakness of the Gen 1 SBC is the smog-era heads. They have poor flow and low compression for high HP build. Very fixable, but starting out with a purchase of new heads can jack up the budget quickly.

my idea was not anything crazy just a good cruiser that does some off road sometimes. I like the torque don’t care for high revving motor especially in a 2500 suburban. Don’t really have a market on a remote island for engine swaps. want a reliable motor that can run on regular pump gas. Heads and cam are probably the reality. I was just looking for ideas or if there’s been similar builds out there. Thanks all.

One thing to consider is putting a leg in it. There's no substitute for CI. Scat parts are decent even made in China.

First thing would find out of the heads are usable. If not, that decision is already made. In reality if the heads need a lot of work [money] buy an aftermarket set. Wish I would have done that on my last 350 but it was during the Covid lockdowns, nothing was available. Both heads were cracked, cores I found needed a lot of work. Motor runs ok but not exactly a head snapper.
