sure would melt in a 20000 lb vee bottom.

could be wrong but isn't there a 30 skater running around with a pair ?

as for the art of keeping bbc's together, no one mastered that for any extended periods like seen in nascar. this is one of main reasons unlimited offshore racing saw a major decrease in laps and true open water racing.

next the day of superchargers/blowers is gone with the Merc 1350.

valvetrain, valvetrain, valvetrain....plus no blower belts.

cant count how many times heard would have been first, would have won...... but lost a belt

better luck trying other forms of ar racing dirt track or other circle. much larger market

Actually my builder has built LSX motors making over 900hp N/A for racing purposes. They've also built N/A Big Block motors making over 1600hp.

This thread isn't about my builder nor my particular build. I was simply implying that new builders coming into the market should take advantage of the LSX type motors and their potential.

im with you on the lsx engines, give them time there coming to the marine industrie.

i agreed johnny, Ive built and raced ford pushrod engines for years and as a pro wrench the gm ls engine platform is a force to be dealt with. I am sure there is a market for light weight high rpm high hp marine engines. I am not a pro engine builder and know chit about building high perf marine power but I feel the ls engine platform will find its place.

Were a fairly small custom engine builder (15-20 engines a year)...and so far this has been our busiest winter in at least 10 years

If you think there is nothing magic about marine engines, offer one of the big boys a pair to test for you:

Hitch a 14,000 lb trailer to your Denali and drive WOT up Pikes Peak 12 hrs a day. It will blow! That is the duty cycle marine motors go through

Well guys GM is betting big on the LS series engines. GM has a booth at the Miami boat show, on the wall over behind Mercury, and they brought cut away's of the Duramax, LSA, LS? 5.3 and a V6 I believe.

You can purchase a LSA marinized from Indmar and Cruisader (I belive, they are directly across from Mercury), and these engines are a fairly good value for a 560 hp engine. Of course these engines have the VVT that GM developed so there is a lot of new technology in these engines.

What would it take to come into the MARINE engine market? Nothing, what would it take to enter the market successfully? A lot. Emissions are coming and coming hard. If you cannot play in that game then best stay small and local as there are rules for the big boys.

Technology: You have to make an engine that is like getting into a new car, and preferably a Mercedes as anything else is a waste of effort. The thing better pur smoother than a fat cat, start faster than a women can get mad, accelerate like a drag car, live like a Toyota Corolla, sip gas like a hybrid, be light as your dream girl and cost less than an ex wife.

Not asking for much but when someone steps it up and lets the results be heard over their mouth then you will have something. Else there is already an engine supplier out there building the everyday ordinary engines wondering how can I enter this market.

what kind of torque does an lSX make? Ryan you forgot one of the oldest builders on your list....

the "G" man???
