I have a small block chevy iam trying to find the year cubic inch and horsepower it would probably be in the 60s the numbers on the passengers side front block are T0107HCR and the numbers on the block on the drivers side are 985880 and what we be the best plug for this engine thanks
Best I can find is this for the engine code: HCR 1966 327 275 4 powerglide, Rochester Carb
That block number doesn't appear correct though, I check
that sounds about right that was what the seller said it was in the 60s
327 but didnt know the horse power thanksMotorsForum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
