1952 OLDS engine & trans swap

[postalguy]

Greetings, I'm interested in upgrading the original 303 V-8 & original trans, any suggestions as to what yr. & brand of engine and trans would require the minimum modifications and cost? The 303 currently in the super 88 has cracks in both heads and I'm having no luck locating replacement heads, so maybe an upgrade is the best way to go? Thanks for any advice...George

Where are you located as I know of a bunch in some local junkyards. Jeff

too bad you weren't handier-got a pair of '55 heads that I'll probably never use-lots of heads around-saw some '56's on ebay not too long ago-they don't go for real big $ mostly cuz of cost to ship...pete

Thanks, Jeff and Pete, in response to Jeff; I'm in Los Angeles, Ca..

Response to Pete; I've seen some heads for 55-59 olds on E-bay, however, when I contact the sellers they advise me that those heads are not compatible with my 303 eng. Estimates I've gotten so far for a complete long block rebuild (including welding repair for the heads) runs from 2600 - 3100. Thus my reason for considering an engine upgrade.

Thanks for your input guys, not in a hurry so I'll keep looking...George

If you don't know it, 303 engine was basically the same from 1949 through 1953.

If you are intent on installing another type of engine, I suspect Chevy

small block V8 would be easy swap. But, you would have upgrade voltage

12 volt if you haven't already.
