Casting Numbers Question
I'd like to know more about these heads. Casting No. 3991492. It's cast iron with angle plugs. I'd like to know what size valves and combustion chamber volume. I also like to know more about #1110385, a delco-remy dual point dist with no vaccuum advance with tach drive. Is this an original corvette distributor? If so, what year?
Thanks so much in advance:

Re: Casting Numbers Question (bungoo2u)
Neither of my "By the Numbers" books listed them. I seem to remember that these were only sold over the counter (may have been called turbo heads?) and were hipo replacements so would guess at small chambers (64cc) and large valves (2.02/1.60).
Nothing on the distro-looks like it is before a 1965 model-maybe.
Again I don't have anything saying that-just memory from reading stuff...

Re: Casting Numbers Question (bungoo2u)
According to my numbers book, the heads are 1973 350 heads used on camaro and corvette. High performance, angle plug. Probably 2.02/1.60. Sorry but my book doesn't list that casting number for a distributor. The closest numbers to it are #1110847 which was used on 1955 & 56 passenger cars and corvette. The ones on the corvette were without vac advance and #1110855 which was used on the 55 corvette but it had vac advance.

Re: Casting Numbers Question (bungoo2u)
I find heads as:
3991492 1970-73 1.94 / 1.5 or 2.02 / 1.6 so could be either size valve. 64CC over the counter heads, double hump. If they came on a car, it would be an LT-1 with straight plugs.
Don't find the dist #.
