Back to the topic, I find it funny that people are suggesting Ilmors, and new LSX motors. I could not see putting $50,000 dollars worth of engines in a $15,000 boat. kind of reckless suggestions.

Seriously, like I and many others have said. There is a reason why we all have BBC's in our boats. Big boats need a lot of torque to plain off. The engines also build more power in the lower RPM range with huge torque numbers. I have a 489 stroker engine, you make that with a 454 .030 over and 4.25 crank. If you do not have the money for a custom roller get a flat tappet cam with similar specs to the 420 mercs. You can easilly build somthing in the 450HP range and run 5400 RPM.

Thanks, that means a lot. With all the badazz boats out there you looked at mine and it helped you make your decision.

I might be a little bit wrong on how I worded "wreckless suggestions" but I see simple topics such as BBC vs SBC and see people suggesting putting $80,000 in engnes in $20,000 boats. Which you (UD) did not, you only spoke of your good results with your SBC's
I just read a thread the other day when some guy asked a simple question, if he should add an innercoolers or jump up to the next size blower for his 525sc's (454's). This was a really nice '80's boat. There was someone who said "if you can swing it, I'd go with these" and there was a link to $56,000 Teague blower motors. WTF
Sorry if I offended anyone

yes,you can make a lot of power with a small block,but it comes at a price.dollar for dollar,the bbc makes the most sence.as already stated,bbc parts are everywhere,and reasonably priced,as eddie and ray said,go with the bbc,these guys doo this for a living,and they know what they are talking about.you can find fair deals right now on oso classified,on good used takeout engines.if you decide to go with the small blocks,it will cost you more to go the same speed .good luck with your project.

No worries- and thanks for the reply.
I didnt see that quote...although that would be nice..... I totally agree
... thats a far cry from the posters questions and not really a practical answer.
Buying from Merc, Teague, Eddie, Gellner, Ray/Larry, Ilmor is like an insurance policy. No one ever went wrong cutting checks to these guys. Anybody with dough can do that.
I think we see lots of "non advice" and "of course" suggestions because guys in our hobby are eager to share what works with fellow boaters, and then..... the other type of guy thats trolling and feels compelled to chime in about s%!t they know nothing about- these are the guys that irk me.

the 30 Panther has an 8' beam , so big blocks would be a PITA to work in between just to change plugs. My boat has 8' beam
and I can barely squeeze between the engines to do so , but doable.I can manage to do a starter change or work on the cool fuel system as well. Couldn't be done with BB's without some dismantling .6.2 [ 377 cu] takeouts and 383 engines can be found !
