OOoof!
I started this with good intentions but it didn't occur to me that to some, a sudden windfall of cash may be better spent on bills, food, clothes or alimony.
I actually have plans to sell a car in a few months and expect to have a few extra bucks from it. I like leaving the savings accounts alone...I try to fund my projects with the
money on the side.
When I first built the 440/493 for "Ginger", The rotating assembly came from a shop that told me that it would run fine on pump gas. IT did not.....10.8 to 1 compression with 91 octane gas might work with computer controlled new cars but it didn't work for me. I asked around for advice back in 2011-2014 and got many good suggestions. One was to try using a bigger cam.
The theory behind that was that a bigger cam with a later intake closing would reduce the cylinder pressure enough to eliminate detonation. I tried a wild Lunati that had .556/.578 lift I/E and something like 271* duration. The car ran like a rocket with that cam but knocked
worse.
Later I learned that whatever reduction in detonation that one might see at the low rpms comes back with a vengeance at higher rpms.
I didn't want to pull the engine out so I went with thicker head gaskets. It did eliminate the knocking but I know I'm leaving power on the table by losing compression and quench.
What I should have done is pull the engine and install dished pistons. I have a 11-1969 virgin block that I could use but I'd rather have something dated from July or August. My car is a December build so it would be nice to have what could be a date code correct block. It is silly, I know since there isn't much to my car that is original or correct anyway.
A fresh set of pistons and rings, Those TF 240 heads, keep the compression around 10.5 with good quench and it should be a 600 HP monster!
