Hi guys!
I have a 1984 stinger 260 with twin 350-275 hp engine, running roughly 58 mp/h.
Any body runs 454? or 502's?
What speed are you guys getting, with how much HP???
I may go bigger engine but don't know how big I should go!

Hi Jeff,
I'm not sure how fast that hull was designed to go, but I'll bet not faster than 70.
I have twin SBCs (stockish 260hps) I have Cobra drives and 23P Rapture props. (1987 Stinger 260)
I see 52 or 53 on my GPS in "good" (slight chop, no big waves) water with a half tank or less.
Glassdave has fresh 350s on a 85 Scorpion with Alphas and I think he sees the high fifties. Maybe 60.

yep, i have twin smallblocks warmed up just a bit. they are probably around 3oohp and the best i have seen is 60.9 on gps. i have alphas spinning 23p quicksilvers. thinking about switching to vortech heads and airgap manifolds. right now im over proped and only see about 4500rpm wot. with just a bit more HP i think i can make better use of my props. ![Cool](/forums/images/smilies/cool.gif)

Consider putting 383 strokers in it, I own a stinger 260 with facotry 260s but I looked at one with 383 strokers & Alpha SS drives that radared at 84 mph. 26P props. I should have bought it but I was a little worried about having to replace the drives too soon but the Bravo 1s would hold up.

I think he is being a little optimistic.
Maybe his motors have been "warmed up" and he has the perfect props.

hate to say it but i would be surprised if it went 62. maybe on pitot speedo but not actual gps numbers. i would guess 57/58. thats still pretty good though. for whats its worth my boat isn't what i would call fast but i love it. plenty of room for long weekends, performance i can live with and it doesn't eat me alive with broken parts. if you are interested in something like this i am hoping to move into a 31 sonic later this year and mine will be for sale. fresh paint/interior/engines would like to get in the 14/15k range out of it.
