Just purchased 340 with drive train

I have been looking for a running 340 for a while now and hope to find decent A body to install it in.
Recently ran across one in an 1982 D150 of all things.I was leary at 1st but checked all he numbers and its a 68 build engine with correct heads. The intake has been changed but other then that it seems to be all the right stuff. Also has built 727 in it.
The truck had been sitting several years but engine wasn't stuck. Did all the pre start stuff and it started right up. Didnt run but a few mins cause carb needs rebuild and gas started running out the top.Sounded great and no smoke. Now in process of rebuding carb so I can get it smoothed out and maybe even run it in the truck for a while till I find decent body.
I found correct intake on ebay and plan to put carter carb back on it ( Holley now)
With all that being said is there better value in trying to keep it stock as far as intake and carb or just get new after market stuff?
Thanks
