thanks for the write-up.
I got a 273 some took the front off, heads, and intake etc. is there anything I need to know different when I put it back together??? its just a 65 2 bbl 273, going back stock.
I would upgrade the timing chain to a true roller double roller. It's a step above the stock 340 double roller chain and will last a long time. The original chains that they put in the 273 & 318 are single row with plastic coated gears. They stretch easily and I've replaced them as early as 84 k miles, and gotten almost 2 MPG increase. The true roller double rollers can go over 200 k without stretching very badly on a daily driver.
