Tantrum Finally Ready
Finally have the new motor broken in and tuned on my 96 tantrum. I bought a rebuilt 454 with 0 hours of another OSO member. Motor was built with all Quality parts. No dyne numbers but should be in the low 400's. Spun a 21p rev4 to 5200 rpm's at 62.5 mph. Roughly the same number with a 21 mirage( not plus) I'm thinking a 23 mirage plus will be the best fit. Any thoughts based on my numbers.

Confused.... Tried the 23p mirage and got the same exact reading as 21p rev4 and 21p mirage. Thinking tach may be off so I ordered a new one. What am I missing here they only time I got a different reading was with a 25 mirage. I got 4800 rpm's but got the same top end. Speed is measured with a garmin.
