Pistons

Holy crap!! 1700 CDN? Check with Summit. They sell TS rings under the Summit brand and I can’t say for sure but I’d be surprised if you can’t find that ring for half of that money.

The biggest reason 5/64 rings are still used is the “market” thinks a thick ring seals better (it doesn’t regardless of who thinks they do) and the piston manufacturers aren’t willing to change up the tooling.

They shouldn’t make pistons that take those big assed, clunky rings.
That is the cost of the pistons and rings through Summit. Remember we get hosed for the $ exchange at 1.4 these days and our prime peckerhead spashing money around to appear as a world savior is only getting us deeper in debt which eventually sink our $ more. I already have most of the stuff for the heads, valves, screwin 7/16" rocker arm studs, roller rockers, guide plates and hardened push rods. That is up in the $1200 range alone, and then the guides and machine work will be up there also. So rebuilding my 289 will be close to $5000 CDN by the time I am done. Yup, costs us a fortune. Housing is pretty expensive with having to dig a basement and pour concrete walls to 6 feet in the ground to get below where the frost gets over winter.
