Serious 340 build into 361 HiRPM Screamer

It was a Crower SFT.

I don’t recall the specs exactly(built it close to 30 years ago), but something like 263/265-108, .575/.585.

It was in the catalog on a 105 or 106, and I had them do it on the 108.


How much head work? Also what intake and headers? Oh yeah, how much compression?
