Small block info needed

[Robert]

Looking at a fitech efi. It comes with the 350 motor it's set up for. If I want it. The block number is 10066038.  92 ish 4 bolt main, made in mexico. Don't know much about motors . Can I use parts from the 350 I have now.  Original  70 010 block late model heads. Has comp cam and roller rockers ( needs bottom end rebuilt ). Yes I know its a no brainer. Efi and motor delivered for cost of the efi.  Thanks

Yes, you can use the older parts on it. The small block didn't change till the lt1s of the 90s I believe. The ones with no distributor and the optispark with the wires by the water pump. Only some parts will interchange with those.
