Hey guys. Recently was able to play with te boat with a gps. 272 sr1 with twin sbc. Not sure of internals as I bought the boat this way. Definitely edelbrock and Holley dual feed carbs. Just was able to clock 54 knots. 54.2 to be exact. Max speed after playing in different directions and trim. Should be in the 64 mph range based on knots to mph conversion. Curious what you guys think.

Also I have not confirmed the props but was told they are 24's

88242LS

I think the stock numbers on the twin SBC are around 58/59, I'd say your doing well

formula 382 sr-1

Our old 272 (1987) with 350 mag's run 55 to 57 mph on gps. With the 383's 425 hp it ran 69.9 on gps @ 5600 rpm.

Like I said unsure of internals. Don't know if they are beefed up as far as cam or heads. Just sure of edelbrock intakes and Holley carbs. I was pleased with those numbers.
