Fit my 454 Big Block
This was exactly what I needed for my 1974ish, Block SN#3999289, 454 Big Block chevy. I am rebuilding an old 60's car and have installed a 454 big block. I try to order parts on line and many times the parts do not fit. This part fit the this application. Includes the bolts and rubber seal too. You also need to order a thermostat. I bought this one https://www.amazon.com/dp/B000C5CE0W?ref=ppx_yo2ov_dt_b_fed_asin_titleCheers
