When i have them dyno with bigger carb, wonder if it would be worth changing cam to 106lsa or 108 to bring peek down, my other 514 peaks at 5500 but cant find that cam card.
Im keeping this boat,  selling southwind some day. Id like to push this one as hard as i can. Limits to delta bottom speed?has port matched victor. ..took me awhile to figure out how to reply.. Lol ...waiting to sell the existing 460 with 5hrs on it before pulling for new

Newbie,  sorry if i have posted in wrong place... My first post/cherry popped ect.. . Ive lurked and read almost every post for months. Butt.. Figured id just join and ask.. I will not be building my own pump- itll be ss but should i shoot for 9.5 and hope to pull 4700 or b/c and hope for 6500
Eliminator, bubble, 18'full stringer, no floor..530 bbf engine was tested exactly like it will be in boat..engine guy thought it was for prop boat .should i have cam changed to shoot for max tq/lower rpm ..solid roller now
carb was only 750,  if cam change ill take dom carb off other boat and test.
Didnt want to call a pro shop yet and get stuck with salesman- not a tech ect
Whew that took me forever to type,  thanks

Do you guys have petcocks in place on your motors? I'm replacing a 454 with a another and the original motor has them installed. I've never had them on previous boats and would appreciate your thoughts.

I live in Mohave Valley, AZ and the boat will be stored inside in a climate controlled environment.

Thanks for your help

Food for thought on ring end gaps....

I was just at SEMA 2018 talking about this exact subject with one of the reps from United Engine Machine (ICON, Kieth Black, etc).  He mentioned he used to work at Perfect Circle so I asked him what he thought about larger ring end gaps as I've always added a few thousandths to the recommended spec for safety and have never had a problem with blowby.  He said PC actually ran tests on end gaps and in a dynmaic running engine they could not measure any difference in blowby from a 0-gap ring on up past .040" gap.  Static leakdown tests will disagree, but in a running dynamic engine there was ZERO measurable blowby difference.  Honing technique (pressure, speed, final finish, etc) has a much greater affect on ring seal and blowby.  The take away for me, and he concurred, was that larger gaps have no performance drawback but will save your motor if it gets hot.  I thought it was interesting the way I was taught by the "old timer" jived with a manufacturer's test.

I've always set pistons a hair on the loose side as well.  When I say hair I mean +.0005" or so.  Same rationale, building durability and a little wiggle room into the clearances.  I probably would be more conservative on a short skirt piston but Speed Pros have a long skirt and are much more forgiving.  I wanna say we put .0055" into my buddy's 429 Ford, but his compression was up over 11:1 and he runs it HARD.

It does help. The rings say to be .004 per one Inch If bore and it’s a 454 bored .30 over. What should I set the ring gap at?
