Re: 242LS 65mph - how to get there?
 

Chuck, sorry to hear about your engine, I did order an engine from the place you posted and I have 120 hours on it and runs great 454/350 hp. I know it`s not a high HP engine but it runs every weekend :drink:

Re: 242LS 65mph - how to get there?
 

Well it turns out the "420HP" motor they advertise is made out of unobtanium....they are not available. The guy I spoke with said that they only sell 454 long blocks with oval ports...where as I have square ports...so their only option is a 502 "435" hp.

From what I understand, runing a 502 would require:
long block
electric fuel pump
flywheel
oil filter relocation kit (not sure why)

Plus I need manifolds/risers because mine are toast.
I was told that I can use my existing intake manifold and carb...but is a 750 cfm carb enough for a 502?

Guess I'll start a thread on the tech board to see what other options I might have.

My buddys 509 cu in 535 hp made LESS with an 850 carb. He's running a 750 to get the 535 hp

Interesting. By the way, what exhaust is your buddy running?

Re: 242LS 65mph - how to get there?
 

Gil Offshore

Probably because my buddy (who knows and uses my OSO password) has one!! :p

Re: 242LS 65mph - how to get there?
 

Very cool. Hate to ask a million questions...but were there any fitting issues with the exhaust? I'm trying to decide between "standard" exhaust and performance exhaust.

The easiest way is on the trailer!!!! :evilb: :evilb: :evilb: :drink: :drink:

Re: 242LS 65mph - how to get there?
 

The only "fitting" issues involved was the fact that the Gil tail pipes were wider (center to center) than the holes in the transom :( . Each one was about and inch "outside" the transom hole. This was easily corrected by elongating the holes in the flange that bolts to the manifold. 1/8 inch on each and the pipes moved closer(center to center) by almost 2 inches at the far end. This was a problem because of the length of the Gil tail pipes and only and 8 inch piece of rubber hose on the end and that was a lot of offset to make up for in and 8 inch space.
